AMD launches three Radeon 6000 graphics cards with ray tracing and RTX beat performance•Eurogamer.net



It’s time Big navigationAMD has introduced their new Radeon graphics cards: the RX 6800 for $579, the RX 6800 XT for $649 and the RX 6900 XT for $999. AMD claims that these graphics cards should be able to match or beat Nvidia’s flagship RTX 30 series graphics cards, all the way to the $1499 RTX 3090, which is usually cheaper and consumes less power. The 6000 series cards are also the first desktop AMD GPUs to support real-time ray tracing, variable rate shadows and other DirectX 12 Ultimate features. All in all, this is an exciting package for AMD fans-and Nvidia users who may be frustrated by the poor availability of the RTX 30 series.

The performance here is what most people want, so let̵

7;s get started. In AMD’s slides, they showed the 300W RX 6800 XT vs. 320W RTX 3080 under 4K. The sales of AMD cards in Battlefield 5, Call of Duty Modern Warfare and Forza Motorsport: Horizon 4 are very small. The losses in Partition 2 are small, Evil 3 and the young blood of the German headquarters. In other places, such as “Destruction Forever”, “Borderlands 3”, “Gear 5” and “Tomb Raider”, these two cards are almost equal. The same is true for 1440p. AMD graphics cards remain competitive in every title displayed.

At the same time, RX 6800 looks to be competing with RTX 2080 Ti and RTX 3070. AMD’s marketing materials show that the 6800 fully beats the 2080 Ti at 4K and 1440p, usually competing by 10% or higher, although the slide points out that this is a feature that enables smart memory access, which requires Ryzen 5000 processing Device (more on that later).

The situation of the flagship product RX 6900 XT is similar. Although the price is 500 US dollars cheaper, it can still match or beat the RTX 3090 at a pretty good price-but again, this is a card that enables smart access to memory and overclocking, so it It will be interesting to see how these cards compare in stock speed and when using Intel processors.

<p>So, how does AMD bring such amazing progress from a (small) Navi GPU like the RX 5700 XT? The company’s Infinity Cache system is an architectural change. The system is based on Ryzen’s Zen L3 cache and allows Big Navi’s 256-bit memory bus to use less power while reaching 2.17 times the bandwidth of the traditional 384-bit memory bus. While using the same 7nm process, the graphics card clock frequency has also increased by 30%. Combined with improving the efficiency of the computing unit itself-AMD pointed out “universal fine-grained clock gating, aggressive pipeline rebalancing and redesigned data paths”-and you have a higher performance GPU.</p>

RX 6000 specifications CU Boost clock Virtual RAM Unlimited cache Technology Development Plan price
RX 6900 XT 80 2250 MHz 16GB GDDR6 128MB 300 watts $999
RX 6800 XT 72 2250 MHz 16GB GDDR6 128MB 300 watts $649
RX 6800 60 2105 MHz 16GB GDDR6 128MB 250 watts $ 579

Let’s take a look at the specifications starting from the RX 6800 XT. The card uses 72 CUs (computing units), 2250MHz enhanced clock, 128MB infinite cache and 16GB of GDDR6 memory. 6800XT can also perform power management with lower power consumption (300W and 320W) than RTX 3080. At the same time, the RX 6800 has 60 CUs and a 2105MHz boost clock, but has the same infinite buffer and VRAM distribution. Its TDP is 250W. RX 6900 XT was a timely “one thing” at the end of the show. It is a fully functional 80 CU version of RX 6800 XT, with the same clock speed, memory configuration and 300W TDP.

<p>Although the hardware shown is impressive, it has two performance-enhancing features. Berserk mode is a one-click GPU overclocking button that should be able to safely maximize performance from the graphics card, and a feature called AMD Smart Access Memory allows the Ryzen 5000 processor to easily access Radeon 6000 GPU memory to enhance frame performance. Rate further. When this feature is enabled in the BIOS and used in conjunction with “Furious Mode”, AMD’s gaming performance has increased from 2% to 13%-although single-digit improvements are more common in AMD’s marketing materials. In addition to increasing the frame rate, AMD also updated Anti Lag and Radeon Boost to reduce input lag in GPU bound scenes. </p>
<p>As mentioned above, the RX 6000 series will be the first AMD GPUs to support DXR ray tracing and other DirectX 12 Ultimate features, but we don’t have a very good idea about the ray tracing performance of the new card, so we hope it will be soon detailed.  AMD has not announced the DLSS feature of its true competitor, Nvidia, which can significantly increase the frame rate of supported games to help offset RT costs, so we will have to see if a similar situation will occur later. </p>

But how about ray tracing performance? ?

In order to verify these claims, we must use the Radeon 6000 to conduct our own tests, but in general, this is a very impressive discovery for a company that cannot reach the highest level of Nvidia graphics cards with its previous generation products. RX 6800 and 6800 XT will be released on November 18th, and RX 6900 XT will be released on December 8th, so we don’t have much time to wait!
