Tag: AMD Radeon RX 6900 XT

The AMD Radeon RX 6900 XT is here! This is the company’s new flagship graphics card, targeted at maxed out gaming at 4K UHD resolution with raytracing enabled. The Radeon RX 6900 XT was announced alongside the RX 6800 XT and RX 6800 back in October—today is the launch. The new RX 6900 XT is based on the same 7 nm “Navi 21” silicon, but maxes it out with all its shaders enabled, the highest clock speeds among the three cards, and the highest possible overclocking headroom. AMD in its October announcement for the RX 6000 series stunned the gaming community by announcing that its latest cards offer competitive performance with NVIDIA—the RX 6800 XT is in the same performance league as the RTX 3080, and the RX 6900 XT gets close to the RTX 3090 while beating the RTX 3080.

For the most part, the RX 6800 XT and RX 6800 lived up to their hype, with the RX 6800 beating the RTX 3070 and the RX 6800 XT trading blows with the RTX 3080, but only in the majority of our game tests that lack real-time raytracing. With raytracing enabled, the RX 6800 series cards perform closer to previous-generation high-end “Turing” models, such as the RTX 2080 and RTX 2080 Ti. Still, there’s enough for AMD to claim a return to the high-end graphics segment after many years. The new RX 6900 XT being launched today offers the very best from this generation and is targeted at enthusiasts or gamers who want the best AMD has to offer for 4K gaming.

The Radeon RX 6900 XT is being launched at an SEP price of $999, which lets it sit in the vast pricing gorge between the $700 RTX 3080 and $1,500 RTX 3090. If AMD is claiming that the card trades blows with the RTX 3090, it must beat the RTX 3080 to justify the $300 higher price and get close enough to the RTX 3090 to lure in buyers with the $500 lower price.

The RX 6900 XT is based on AMD’s new RDNA2 graphics architecture, which debuted earlier this year with the GPU that powers the PlayStation 5 and Xbox Series X/S. This is important for AMD’s RX 6000 series, as game developers build their game engines around consoles first since that’s where the money is, and it minimizes effort for them to optimize their games for the RDNA2 architecture on the PC. The biggest feature addition with RDNA2 is full DirectX 12 Ultimate API support, which includes real-time raytracing using the DXR API, Mesh Shaders, Variable Rate Shading (both tier-1 and tier-2), and Sampler Feedback. AMD has also bolstered the card’s feature set with an updated Radeon Anti-Lag, support for DirectStorage API, and resizable BAR (Smart Access Memory).

In this review, we take a very close look at the AMD Radeon RX 6900 XT. In its launch presentation, AMD claimed that the RX 6900 XT performs in the same league as NVIDIA’s RTX 3090, but this claim came with a big asterisk—the Smart Access Memory and Radeon Rage mode overclocking features were enabled. In this review, we test the RX 6900 XT out of the box, at stock settings and on our regular VGA test bed, as well as add a data point measured on a Ryzen 9 5900X-powered machine with SAM enabled to show if the RX 6900 XT is capable of competing with the RTX 3090.

AMD Radeon RX 6900 XT graphics card ‘flagship Big Navi GPU’ benchmark was spotted within the Ashes of The Singularity database by TUM_APISAK. The graphics card which launches two days from now will feature the full-fat Big Navi GPU configuration & compete against NVIDIA’s GeForce RTX 3090 for $500 US less.

AMD Radeon RX 6900 XT Flagship Big Navi GPU Benchmark Leaks Out Again, Almost As Fast As The GeForce RTX 3090 For $500 US Less

The AMD Radeon RX 6900 XT is the fastest GPU that the red team will have ever produced. It aims for the ultra-enthusiast segment and is directly competing against NVIDIA’s flagship GeForce RTX 3090. The main difference between both cards aside from their vastly different specs is that the RX 6900 XT features a price of $999 US whereas the GeForce RTX 3090 features a price tag of $1499 US.

These are official MSRPs and given all the supply issues affecting AMD and NVIDIA GPUs, it will be hard to find the cards at those prices and that is even if you can find a graphics card. But AMD does have the price advantage over the RTX 3090 so it should all come down to performance.

The Ashes of The Singularity benchmark was tested with the AMD Radeon RX 6900 XT with a Core i7-8700K CPU and 32 GB of DDR4 memory. The Crazy preset was selected and a 1080p resolution was used. This in no way should tax the GPU but regardless, the RX 6900 XT scored 102.1 FPS. The RTX 3090 scored a slightly higher 105.4 FPS. This shows that the RTX 3090 is 3.33% faster than the RX 6900 XT. The RX 6800 XT is also shown to offer the same performance at 102.0 FPS which could mean that the benchmark is underutilizing these cards at 1080p. Only cards of a lower-tier such as the RX 6800 and RTX 3070 show a bigger difference here.

With all said, both the RTX 3090 and RX 6900 XT do have their own advantages. To name a few, the RX 6900 XT should offer higher efficiency, better rasterization performance, and comes with Infinity Cache and SAM support which helps deliver higher frame rates. NVIDIA’s GeForce RTX 3090 on the other hand offers insane content creation performance, 24 GB of GDDR6X memory (8 GB more vs RX 6900 XT’s 16 GB), and features faster and better-looking ray-tracing effects.

As such, the AMD Radeon RX 6900 XT could end up sitting comfortably ahead of the RTX 3090 at higher resolutions and this is just one title. With the RX 6800 XT, we saw that the card gave the RTX 3080 a hard time and even came close to the RTX 3090. The RX 6900 XT with its higher number of cores and a maximum clock limit of 3 GHz should surpass the RX 6800 XT with ease.

The AMD Radeon RX 6900 XT will come packed with the Navi 21 XTX GPU which is the fully enabled die featuring 80 Compute Units or 5120 SPs. The card will also feature 16 GB of GDDR6 memory across a 256-bit bus interface, a 512 GB/s total bandwidth, and clock speeds of 2015 MHz base and 2250 MHz boost at reference specs. There are also 80 Ray accelerators for ray-tracing enablement on the graphics cards (one RA per Compute Unit). The graphics card will feature a TBP of 300W.

In addition to the standard memory, the Radeon RX 6900 XT graphics card will also feature 128 MB of Infinity Cache on the GPU die. The cache will help boost bandwidth for higher performance at resolutions beyond 1080p HD. The 128 MB Infinity Cache boosts the standard 512 GB/s bandwidth by 3.25x, delivering an effective bandwidth of up to 1.664 TB/s across all Big Navi GPU based graphics cards.

Overall, it will be good competition from AMD, and overclocking-wise, the RX 6900 XT is going to knock the pants off the RTX 3090 but expect the card to be sold out within minutes of launch since its a very niche and high-end product with limited quantities as we have heard from our sources.

AMD’s Radeon RX 6900 XT, the flagship Big Navi GPU based graphics card, launches next month & is expected to compete against the GeForce RTX 3090. Twitter fellow, Patrick Schur, managed to get access to the BIOS of the reference AMD Radeon RX 6900 XT which reveals a higher max frequency than the RX 6800 XT.

AMD Radeon RX 6900 XT Max Clocks Rated at 3.0 GHz, 200 MHz Higher Than The Radeon RX 6800 XT

The BIOS was accessed and its specifics were listed within the MorePowerTool which lists down various parameters such as clocks, the power limit, and fan speeds. The AMD Radeon RX 6900 XT seems to feature the same fan profiles and power limits as the RX 6800 XT however, the minimum power limit is raised from 6% to 10%.

The most interesting thing is that the AMD Radeon RX 6900 XT reference model should come with a maximum graphics clock of 3000 MHz or 3.0 GHz. That’s 200 MHz higher than the 2800 MHz or 2.8 GHz max clock of the Radeon RX 6800 XT. Using LN2 cooling, overclockers were able to achieve the 2.8 GHz maximum clock speed of the RX 6800 XT and able to break the single-GPU 3DMark world-record.

Now having a wall around the limits of the max clock overclocker’s ability to push these graphics cards further since they are hitting the wall easily when running the card on LN2. The RX 6900 XT should allow overclockers slightly higher headroom which is a first for any high-end GPU (to hit 3.0 GHz) but at the same time, overclocking it further would be a no-go unless they can bypass the limit with a custom BIOS.

The AMD Radeon RX 6900 XT features more than just higher clocks. It has more cores and a faster-binned GPU which should allow for faster and more stable clocks. It looks like the Radeon RX 6900 XT will be breaking some big world records when it launches. The card is expected to launch first in reference flavors only but users shouldn’t give up hopes on getting custom models in the future or at least when the RX 6000 series supply gets better.

The AMD Radeon RX 6900 XT graphics cards will be available starting the 8th of December. The AMD Radeon RX 6900 XT is said to carry a price tag of $999 US and is expected to be a reference only model for this year unless AMD gives its AIB partners a greenlight for custom variants which may be in the plans.

I’m knee deep in reviewing NVIDIA’s new GeForce RTX 3080 graphics cards, and now the RTX 3090 to have a day one review, but the world hasn’t stopped.

We now have some new rumored specs on the AMD’s next-gen Radeon RX 6900 XT graphics card, where Rogame tweets it will be powered by the Navi 21 GPU and have 16GB of GDDR6 memory. The 16GB of GDDR6 memory is coming from Samsung, and will reportedly be on a 256-bit memory bus.

Not only that, but there is also the Navi 22 GPU that should power a slightly slower card that should materialize into the Radeon RX 6800 XT, or possibly the Radeon RX 6700 XT. This card will reportedly have 12GB of GDDR6 on a 192-bit memory bus.

There are others that think AMD will use 16GB of faster HBM2 memory on its Radeon RX 6900 XT, and then GDDR6 on the replacements for the Radeon RX 5700 XT, RX 5600 XT, and RX 5500 XT. This also makes sense, as it would make the new Big Navi / Radeon RX 6900 XT more like a “TITAN” series graphics card — a competitor for the GeForce RTX 3090 with its ultra-insane 24GB of ultra-fast GDDR6X memory.

NVIDIA’s new GeForce RTX 3090 drops on September 24.
