Just How Good Is Animal AF on the New Canon EOS R5 and R6 Cameras?

The Canon EOS R5 and R6 cameras have generated a lot of buzz in the past few weeks, but one feature that has not gotten as much attention is their Animal AF capabilities. This great video takes a look at their performance and what you can expect from them in practice. 

Coming to you from Tony and Chelsea Northrup, this great video takes a look at the Animal AF on the new Canon EOS R5 and R6 cameras. Eye AF has been a real boon for lots of photographers in recent years, and the next step has been Animal AF, which can be huge for people like wildlife and pet photographers. It is especially impressive to see how well Canon’s implementation does, often picking out the eye of an animal that is fairly well camouflaged by its surroundings before it can even be noticed in the viewfinder. It is not perfect yet, though; as you will see in the video, there are still sometimes issues with tracking and precision. Nonetheless, it is very impressive technology that is sure to please lots of users, and it will only improve as time goes on. Check out the video above for the Northrups’ full thoughts. 

Razer Opus Review

Even with the number of options out there – and believe us, there’s A LOT – it’s astonishingly hard to find quality Bluetooth headphones in the mainstream sector. There are, of course, the usual shoo-in brands like Bose, Sony, and Beats that most people go for. And, there are those that sit right on the cusp of the audiophile market like Sennheiser, Audio-Technica, and Shure. The rest are either not worth your money or, at best, a hit-or-miss.That means that if you want something other than what these brands offer – in terms of aesthetics, perhaps, or price – then you’re kind of limited. If you’re looking for great quality sound, that is. Razer Opus

That’s why, when I tested Razer’s latest attempt at non-gaming over-ear headphones, I was mildly and pleasantly surprised. This set of cans rivals the likes of Beats Solo Pro and Bose QuietComfort 35 in terms of quality and features, minus the high price tag and perhaps with a brighter sound. I’m absolutely here for them.
Design and Features

If the Razer Opus Wireless ANC Headset has one weakness as a pair of consumer Bluetooth headphones, it’s probably the aesthetic. Not that the headphones aren’t great looking – on the contrary, they have a smart, no-nonsense, minimalist design that will appeal to almost anyone. Razer trims that with its name on both ends of the band, as well as the THX logo on both ear caps, in silver engraving, then wraps it all up in a rare midnight blue coating. (The black shade to follow.)

It’s a clean look, but overall a bit homogeneous and just a tad too familiar. I’ve actually seen this similar clunky style on a pair of Sony headsets or a cheaper Sennheiser long before I’ve ever laid eyes on the Razer. This is, of course, hardly a deal-breaker, but if you’re typically drawn to more unique-looking headphones like I am, you probably won’t get excited about this one.

Looks aside, there’s plenty to love about the Razer Opus’s design, especially in terms of comfort. The top of the adjustable headband is padded with luxurious memory foam that’s almost half an inch thick and wrapped with soft leatherette that’s nice to the touch. As are the ear cups, which are also angled so that they fit around your ears better and sit on your head beautifully. And, while the headphones are tight enough to stay on even when you’re moving your head around, they’re not too tight that they feel like they might be crushing your skull after you’ve had them on for a while.

I tend to have a problem with Bluetooth over-ear/on-ear headphones – even after only a few minutes of wear, my ears and the sides of my skull start to feel the pressure. This hasn’t been a problem with the Razer Opus.

The ear cups also swivel about 90-degrees towards the back, a feature you won’t always find in Bluetooth headphones, but comes in handy when you have it, as it helps in both packing flat in your backpack and accommodating different head shapes. I love swiveling ear cups as I prefer to move one cup off my ear when someone’s talking to me or listening to PA announcements at airports. Although that doesn’t work as well with the Razer Opus due to the larger, angled cups, it’s still a nice feature to have.

There are five buttons here – the essentials: volume up, volume down, play/pause and power, and the ANC/Ambient button that turns the Razer Opus’s Hybrid Active Noise Cancellation function on and off. What this button does, essentially, is it lets you turn off the ANC and pick up a bit of ambient noise around you so you can hear what’s around you without needing to take the headphones off.

The “hybrid” in the name refers to the two-mic system these headphones use for its ANC. It’s got both a feedforward mic, which is designed to cancel low to mid frequencies, and a feedback mic, which is designed to cancel out lower pitch noise. The two work together to deliver a pretty effective noise cancellation.

What I appreciate more here, however, is the nifty Ambient Awareness or Quick Attention mode, which is activated when you hold down the ANC/Ambient button. This function essentially stops the audio and lets you clearly hear your surroundings.

So, instead of you scrambling to hit the pause button, turn ANC off, and push one ear cup aside just to hear airport announcements or have a short conversation with someone, you simply hold this button down. It’s pretty effective too – it’s almost as if a veil has been lifted, and you can clearly hear everything around you even with your headphones still on.

Another Razer Opus feature worth mentioning here is the ability to auto pause when you take the headphones off and auto play when you put them back on. It’s a really handy feature, though I did find it to be app-specific. That is, while it works well with Apple Music, Spotify, iTunes, and YouTube, it hasn’t worked once with Amazon Music, and often has trouble with Netflix.

Of course, it’s also worth noting that although I did have a production model as my review unit, I tested the headphones a week before their official release. A simple update should fix this limitation right up.

Together, these features clearly point to the Razer Opus being marketed towards not just mainstream consumers, but specifically mainstream consumers who are always on the go. These headphones are designed to be used when you’re walking to work, working at cafes, commuting on trains, and flying to your next destination. They even come with their own airline headphone adapter to prove it.
Software

At this point, not much can be said about the Razer Opus app. Available for both iOS and Android, it’s a pretty straightforward app, with just an EQ that’s only customizable with the five available presets Razer has preconfigured for specific situations. Unfortunately, at least for now, you cannot control the EQ yourself.

Besides the EQ presets, you can use this app to set the headphones’ auto shutoff – after up to 1 hour of downtime – and to toggle the Auto Pause/Play feature. It’ll also display how much juice you have left on the headphones, although it doesn’t give you exact numbers, just a battery icon.

What’s most impressive here, however, is that it doesn’t matter which device the headphones are currently connected to. You can control your Razer Opus headphones via the app on your phone, regardless of whether it’s paired with a laptop or a Nintendo Switch Lite or anything else. As long as the headphones have been previously paired and set-up on the app, you’ll be able to switch presets to get the most ideal sound.
Performance

What I’m blown away with here is that although the Razer Opus has a consumer-level price tag, these headphones do sit in the prosumer category when it comes to sound quality. Testing them on a whole lot of songs, as well as several games (Far Cry 5, Red Dead Redemption 2 and Animal Crossing) and a couple of movies (Inception, Spiderman: Into The Spiderverse), I found them to produce a slightly warm sound.

They deliver a mid-low boost, with a very controlled low end that can be had in spades without being overwhelming. Kendrick Lamar, for example, sounded amazing on these cans.

To see how these headphones fare with movies, I chose to watch Inception, as Nolan likes to put a lot of rumble in his movies and a lot of really quiet speaking parts. While it’s not the same as watching the movie on a home theater unit with a sub, the headphones still had plenty of rumble. Even better, the voices were clear and articulate despite all the action and the score that’s playing.

The high-end is also very controlled, although there is some very high end sizzle that gives some songs a bit of harshness (as well as pushes sibilance and cymbal sounds forward a little). This seems to be a Razer signature sound, however. Both the controlled low end and the very high end sizzle are tonal qualities I’ve experienced in other Razer products like the Nommo Pro and the Razer Hammerhead Duo.

The Razer Opus also has a wide soundstage, great enough that you’ll feel immersed in the media you’re listening to, especially music. You could hear individual instruments coming out of different directions, almost as if you’re on stage with the musicians. They’re also excellent for movies – in that one scene in Inception where the whole street starts blowing up, you can hear the different placements of explosions as they appear across the screen.

Sadly, for gaming, while the headphones work well, they don’t really offer virtual surround sound or other tricks of the trade that gaming headsets often tout for a more immersive experience. They’re still plenty immersive though, and should get you through your gaming needs when you’re away from your actual gaming rig at home. Using them while playing Far Cry 5, for example, you could hear characters move from one side to another or yell out from far away.

There are two ways to connect these headphones to devices and handheld gaming consoles – via Bluetooth (4.2) and with the 3.5mm cable included, which gives you a couple of options. Unfortunately, when you take the analog route, you’re also taking away a couple of features: the ANC and the EQ presets. As a result, you’re not only hearing all that noise around you, but you’re also getting sound that’s muddier, hazier and less articulate with mediocre spatial separation.

In short, the sound quality goes down a bit when you go analog – enough that I’d stick to Bluetooth whenever possible. With no notable latency, even in gaming, you can count on that connection to give you the best experience possible.

As far as the noise cancellation feature, there’s a lot to love here. I appreciate the fact that you can turn the ANC on/off, and I love that Ambient Awareness feature that essentially lets outside noise pass through just by holding down a button. Having said that, the noise cancellation may not be quite as good as Bose or Sony’s, both of which have such impressive noise cancellation that they can drown out loud airplane engines.

However, not many headphones can beat those two companies’ noise cancellation technology. The fact that the Razer Opus’s comes pretty close is a feat in and of itself, so we’re not complaining.

When it comes to battery life, the Razer Opus is no slouch. Many headphones offer up to 20 hours of battery life, and the Razer Opus promises up to 25 hours. Even after about 15 hours of use on a single full charge, the headphones still had around 20% battery life left. While 25 hours on a single charge may be a little optimistic, these will at least perform favorably next to other Bluetooth headphones out there.

The Razer Opus Wireless ANC Headset retails for $199.99, and is available in the US, Canada, and Europe as well as China and the Asia-Pacific. It comes in midnight blue and black.

Verdict

If you want impressive sound and a great feature set, there aren’t a lot of consumer-level over-ear headphones out there to choose from outside of what Bose, Sony and Beats roll out, and even fewer under $300. But, Razer didn’t just create another nameless alternative here. The Razer Opus Wireless ANC Headset actually gives the best of them a good run for their money, with its warm, well-balanced sound, wide soundstage, great noise-cancellation, a few bells and whistles, and very minor flaws. And at only $199.99, it might just be the best value noise-cancelling headphones right now.

Surface Pro X begins testing new July firmware update for Insiders

Surface Pro X owners can snag a firmware update for their 2-in-1 device if it’s on an Insider build of Windows 10. We saw the update on a device in the Beta ring, but there’s a chance that the update is avaialble on other Insider rings as well.

We can confirm that the update, dated July 24th, updates the UEFI from 3.510.140.0 to the newer 3.517.140.0.

The firmware update doesn’t have a changelog at this point, but that’s normal for firmware updates for devices on Insider builds. A full changelog should become available once the firmware update becomes generally avaialble. While not set in stone, updates like this generally roll out a few weeks after they hit the Beta Insider ring.

Firmware updates don’t usually include new features, so it’s likely just a stability and performance update, though there’s a chance that it’s related to the new AI feature for eye contact during video calls.

A Photographer’s Review: The Dell XPS 15 Laptop

I’ve lived with the Dell XPS 15 laptop as my main computer for all my photo and video editing for the past year. Should you buy it for your photo editing? Here’s my full review of what it’s like as a creative content maker, warts and all.

As a creative professional that’s always on the go, I wanted to invest in a decent laptop in order to edit my content from wherever I am, whether taking shelter in the car from a snowstorm that blows over Iceland, in a coffee shop in downtown London, or simply sitting at home on the couch. I also wanted the biggest bang for my buck, so that’s why last year, I settled on the Dell XPS 15 9570 laptop.

Why didn’t I just go for a MacBook Pro? Well, mostly because I wanted to get the highest spec laptop for the least amount of money. And before you ask, it doesn’t really have anything to do with the operating system, because I know both intimately and am happy using them interchangeably. So, let’s start my review by looking at the specs I went with, and then I’ll detail how I feel about it now that I’ve lived with it as my main computer over the past year.

Full Specification

CPU: 8th Generation Intel Core i9-8950HK Processor (12 MB Cache, up to 4.8 GHz, 6 cores)

RAM: 32 GB 2x16GB DDR4-2666MHz

Graphics card: NVIDIA GeForce GTX 1050Ti with 4 GB GDDR5

Storage: 1 TB M.2 2280 PCIe Solid State Drive

Screen: 15.6″ 4K Ultra HD (3,840 x 2,160) InfinityEdge Anti-Reflective Touch IPS 100% AdobeRGB 400 Nits display

Operating System: Windows 10 Pro, 64-bit

It’s Still Fast

After a few tweaks in Lightroom this past month, the laptop is still running faster than ever. Thanks to the powerful Intel i9 CPU and the speedy SSD, image buffering and recall are quick. It doesn’t slow down when editing big video projects in Adobe Premiere Pro, either. I run CCleaner every now and again to do a bit of cleanup here and there, tidying the registry as I install and uninstall software, but once you’ve swapped from an old HDD to an SSD, you’ll know that this doesn’t make a huge difference anyway.

Trackpad Repairs Were Needed

I had an issue with my trackpad, in which the cursor kept skipping and jumping all over the page. Occasionally, the cursor would grab onto something and drag it across the screen, which is a real pain in the neck. Luckily it was under warranty, and I had a Dell-approved service repair center fix it for me. There’s a small rubber notch that sits under the trackpad, and if installed incorrectly, the pad clicks and feels odd to the touch. But it took the engineers three separate visits before it was working properly again.

In the end, the service operator had to replace the whole trackpad and the keyboard as well. I was not impressed. I requested an extension of my warranty (which was due to end in just a couple of weeks’ time at that point), but Dell didn’t want to do that. It screamed “planned obsolescence” to me, something that I abhor, but has been okay in the few months since.

It’s Easy to Repair and Upgrade

After the service operator took it apart in my home right in front of me, (this was pre-COVID), I was impressed with how easy every component was to access. A few screws and a couple of clip-on cables looms and most things popped out of the case quite easily. It’s definitely something I’d be happy doing if parts needed repairing or upgrading in the future; there’s plenty of space inside, so it makes things easy to fiddle with. I can’t say the same for MacBook Pros I’ve repaired in the past; they’re a lot trickier in my experience.

Great Battery Life

The battery life in the Dell XPS 15 is great. Even with the larger 15.6″ 4K touchscreen, the battery (6-Cell 97 WHr integrated) lasts several hours happily when out on location editing. When I know I’ll be out shooting and editing all day, or running through airports, I’ll also take my Dell Power Companion (18,000 mAh)-PW7015L, which provides another big charge to see me through another few hours of editing.

The Fans Can Get Loud

If you want to edit big batches of files in peace, then get some music on the go or wear headphones. The Dell XPS 15 isn’t actually all that loud when compared with a new version of the MacBook Pro, but you can certainly tell it has fans when things get going. That’s actually pretty good, because you want a cool laptop so components don’t fry, but pair that with the placement of the vents (on the bottom, towards the back), and you can easily burn your legs if you don’t use a tray when not at a desk. 

Biometric Login Drivers Fail

I’ve repeatedly reinstalled the biometric fingerprint drivers on this laptop, and the issue persists, even after BIOS, OS, and other drivers were updated. I’m not sure why this is, and to be honest, it ruins the otherwise speedy boot time when it goes wrong. That said, there are two other options for signing in, including a PIN and password. But this is more of a Windows 10 feature than a Dell thing. The fingerprint reader feels sturdy though and also doubles as the power button. 

Phenomenal Screen

To be fair, I have the highest spec XPS 15 you can get with the 4K Ultra HQ screen. The full-screen spec is 15.6″ 4K Ultra HD (3840 x 2160) InfinityEdge Anti-Reflective Touch IPS 100% AdobeRGB 400-Nits display, and I can tell you from using it the past year that the touchscreen still works great, and it makes editing images accurately a doddle. It’s the best editing screen I’ve ever used, and I’m so glad it’s in something portable. It’s definitely the best laptop screen I’ve ever seen.

The touchscreen isn’t just a gimmick either. It’s gotten me out of tight spaces when the trackpad wasn’t working and makes certain operations much quicker, as I don’t have to search for the cursor and waggle my finger around on the trackpad or an external mouse.

Should You Buy It?

If you’re happy working on Windows 10 and aren’t bothered with the label on the front, then yes. It outperforms the MacBook Pro at the same price range, and it’s easier to upgrade or repair when needed. It looks great with its metal exterior, has a brilliant screen (we’re photographers/videographers after all), and does it all in a small, neat package.

Also, it plays games well too if you’re into that kinda thing. I’ve got Forza Horizon 4 up on high settings quite comfortably. I would probably say it’s worth dropping to the i7 version if you want to save a boatload of cash or if it’s not your main computer, as you likely won’t need the extra power or a touchscreen.

What is the run time of Kenwood battery?

Kenwood batteries have two main ratings on them: Volts and Amperes. Because size and weight of batteries is limited when compared to larger batteries such as car batteries, most companies show their ratings with Volts and Milliamperes. One thousand Milliamperes equals 1 Ampere. When buying a battery, select batteries with the most Milliamperes (or mAh). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by multiplying the Volts and the Amperes together. For example:

  • 14.4 Volts, 4000mAh (Note: 4000mAh is equal to 4.0 Amperes).
  • 14.4 x 4.0 = 57.60 Watt-Hours

Watt-Hours signifies the energy needed to power one watt for one hour.

What is the run time of Kenwood battery?

Kenwood batteries have two main ratings on them: Volts and Amperes. Because size and weight of batteries is limited when compared to larger batteries such as car batteries, most companies show their ratings with Volts and Milliamperes. One thousand Milliamperes equals 1 Ampere. When buying a battery, select batteries with the most Milliamperes (or mAh). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by multiplying the Volts and the Amperes together. For example:

  • 14.4 Volts, 4000mAh (Note: 4000mAh is equal to 4.0 Amperes).
  • 14.4 x 4.0 = 57.60 Watt-Hours

Watt-Hours signifies the energy needed to power one watt for one hour.

Samsung Galaxy Z Fold 2 leaks in the flesh, showing hole-punch display and name

Ahead of its launch next week, Samsung’s upcoming Galaxy Fold sequel has remained mostly in the dark so far. Tonight, a fresh image of the Galaxy Z Fold 2 has hit the web, showing off the internal display and confirming the new name.

Leaked on Naver (via Max Weinbach), an in-the-flesh image of the Galaxy Z Fold 2 confirms a couple of key details about the upcoming foldable. For one, it confirms Samsung’s new naming scheme. As previously reported, the device is named Galaxy Z Fold 2, following the new series branding introduced with the Galaxy Z Flip earlier this year.

Further, this image confirms the hole-punch on the internal display of the Galaxy Z Fold 2. It’s a bit tough to see given the glare from the logo on screen, but it’s clear the camera has moved and, just like previous reports claimed, it looks to be a hole-punch. Given there are no images of the screen completely on, there’s no proof of whether or not there is a bigger cutout, but it’s certainly exciting to think the notch from the original Galaxy Fold has been done away with.

Hopefully, more images of the Galaxy Z Fold 2 will come from this same user and, if so, we’ll update this article accordingly.

Supermicro SuperServer E302-9D Review: A Fanless 10G pfSense Powerhouse

Intel launched the Xeon D-2100 SoCs in early 2018, with a feature set making them a fit for several verticals including edge servers, networking, and storage. One of the key advancements made in the Xeon D-2100 compared to the first-generation Xeon D-1500 series was the inbuilt support for two additional 10G network interfaces. With TDPs starting at 60W, the Xeon D-2100 SoCs lends itself to some interesting and unique server and edge procesing products. One such system is Supermicro’s passively-cooled SuperServer E302-9D sporting the Xeon D-2123IT SoC.

As part of the evaluation efforts of different technologies and products, AnandTech editors are regularly tasked with the building or identification of suitable testbed systems. The requirements for these systems often mirror the requirements of software developers and homelab enthusiasts. The increasing adoption of 10G across various networking / network-attached storage product lines meant that we were on the lookout for a low-power system with multiple 10G ports to act as testbeds. We reached out to Supermicro after spotting their X11SDV-4C-TP8F-01 FlexATX board. Supermicro graciously agreed to loan us two SuperServers based on the board to take for a testdrive – the E302-9D in a passively-cooled desktop form factor (that we are taking a detailed look at today), and the 5019D-4C-FN8TP 1U rackmount version.

Introduction

Intel’s Xeon D product line targets servers used in power- and size-constrained scenarios (including edge compute). This includes applications across multiple domains such as storage, networking, and communication. The product line integrates server-class CPU cores along with the platform controller hub (PCH) in a single package. The first-generation Xeon D (1500 series) was based on Broadwell-DE cores along with the C220 server PCH. Our launch coverage of the Xeon D-2100 series brought out the details of the updated server core (Skylake-DE) and PCH (Lewisburg C600-series). The relatively power-hungry PCH update and the addition of AVX512 capabilities in the Skylake cores meant that the minimum TDP went up from 20W in the D-1500 family to 60W in the D-2100. However, the updates also brought in welcome connectivity updates.

The Supermicro SuperServer E302-9D / X11SDV-4C-TP8F-01 we are looking at in this review utilizes the Xeon D-2123IT with a 4C/8T configuration. It has the least TDP of all members in the D-2100 family, yet comes with support for up to four 10G ports. The 60W TDP of the SoC allows Supermicro to utilize it in a passively-cooled system. To the best of our knowledge, this is the only off-the-shelf x86 system that provides consumers with four 10G Ethernet ports in a fanless configuration.

The Xeon D-2100 series offers support for up to 20 PCIe 3.0 lanes, 14 SATA 3.0 lanes, and 4 USB 3.0 ports. The D-2123IT can be equipped with up to 256GB of DDR-2400 ECC memory. In creating the X11SDV-4C-TP8F-01 board used in the E302-9D, Supermicro has worked around these features to create a compact board / system that appeals to developers and home-lab enthusiasts working on cutting-edge networking applications.

The SuperServer E302-9D is marketed as an embedded system comprising of the CSE-E302iL chassis and the X11SDV-4C-TP8F-01 board. The power supply is an external 150W adapter. The chassis sports a power button and status LED in the front panel, with all the I/O ports in the rear. The chassis supports a low-profile PCIe card mounted horizontally. The dimensions come in a 205mm x 295.2mm x 73mm. The gallery below takes us around the external design of the system.

In the rest of this review, we first look at the detailed specifications of the board along with a look at the internals of the system. This is followed by some of our setup and usage impressions. In particular, we look at pfSense installation on the system along with some basic benchmarks. Finally, we take a look at the power consumption and temperature profiles before offering some concluding remarks.

CHUWI COREBOOK PRO PERFORMANCE TESTED, GREAT FOR PRODUCTIVITY WHILE STAYING COMPACT

The recently launched Chuwi CoreBook Pro is a 13 inch full-screen laptop which specializes itself in mobile productivity. A great timing as due to the pandemic many of us have been forced to work from home and transform our personal space in a productive place. The laptop also packs some very interesting features such as the light and thin body for a 13 inch laptop, a 3:2 aspect ratio and much more.

CHUWI COREBOOK PRO PERFORMANCE TESTED, GREAT FOR PRODUCTIVITY WHILE STAYING COMPACT

But what about performance? Well, coming with an Intel Core i3 processor, Iris 550 graphics card, 8GB of RAM and 256GB high-speed SSD storage, the laptop is able to go through most tasks without issues. Today the brand decided to prove that with some additional testing.

Before we get into then numbers though, let’s quickly recap the main specs on the CoreBook Pro:

Intel Core i3-6157U processor

Iris Graphics 550 core graphics card

8GB DDR4 dual-channel memory

256GB high-speed SSD storage

Intel WireLess-AC 7265 wireless module

Full-featured USB Type-C

Support M.2 PCIE SSD expansion

CHUWI COREBOOK PRO RUNNING POINTS TEST

The laptop was tested with several mainstream benchmark software such as CPU-Z, Geekbench 4, Cinebench for CoreBook Pro. The running points can be a reference, though they don’t represent the final experience.

First of all, we have CPU-Z to see the details of the i3 processor clocked at 2.4GHz and dual-core four threads. Its final result is Single Thread:240.0;Multi Thread:671.5.

Then the laptop went through the benchmark software GeekBench 4 which can test the overall performance of the processor. And its final result is Single Core:3009;Multi Core:6240;OpenCL:47790.

The result of the Cinebench R15 is CPU:237cb;OpenGL:56.64fps. You can find that due to the excellent performance of the built-in Iris 550 graphics card, the performance of OpenGL is relatively good. There’s also a better experience when hard decoding 4K video or editing and rendering materials.

Next, AS SSD Benchmark was used for the last test. The SSD is one of the hardware parts that most affects daily use. When you open or use some software, both read and write data depend on SSD speeds. The write and read speed of SSD is many times better compared to the traditional HDD. In the case of CoreBook Pro, the reading speed is 518.75 MB/s and 458.88 MB/s for the writing speed. Such read and write speeds are very fast and will bring a great user experience most daily applications.

SUMMARY OF RESULTS

In conclusion, the performance of CoreBook Pro is pretty good. There is no problem in dealing with many scenarios such as office use and entertainment. Even running design software or light video editing should be quite smooth.

POWERFUL PERFORMANCE FOR PRODUCTIVITY

As a productivity laptop, Chuwi CoreBook Pro has many advantages such as the 3:2 aspect ratio for comfortable reading and typing experience. It’s also lightweight, thus very portable and it has a full-size keyboard for a better work flow.

Besides, as we just saw in the performance tests above, the laptop brings more than enough power for productivity purposes.
