AMD nowadays introduced the Radeon RX RX 6000 collection of gaming graphics cards. Developed on the new 7nm RDNA 2 architecture, these cards supply up to 2x advancement in general performance around the earlier generation AMD flagship when also such as assist for the new Microsoft DirectX 12 Final API and will be offered commencing November.
The most important card in this sequence will likely be the $649 Radeon RX 6800 XT. It features 72 compute models and 16GB of 16Gbps GDDR6 memory on a 256-little bit huge memory bus. The 6800 XT can clock up to 2015MHz under load (or Video game Clock as AMD likes to simply call it) and can from time to time strike peaks of 2250MHz for brief durations beneath great conditions (Improve Clock). AMD promises a whole board electrical power of 300W for this card.
The 6800 XT also has 128MB of what AMD phone calls the Infinity Cache. This is superior-density, higher-velocity cache primarily based on the Zen L3 cache. It is developed to limit DRAM bottlenecks, latency, and ability use and is specially successful at 4K and 1440p resolutions. Put together with the VRAM, AMD promises the Infinity Cache presents 2.17x the efficient bandwidth of a 384-little bit large GDDR6 memory.
AMD also had some charts to exhibit evaluating the effectiveness of the 6800 XT to the $699 RTX 3080. We typically acquire these with a grain of salt but in the absence of any reputable third-occasion critiques, these can be taken as a tough steerage.
Upcoming is the $579 Radeon RX 6800. Regardless of staying cheaper, the 6800 would not shed out on significantly in contrast to the 6800 XT. The significant change is to the number of compute models, which has dropped from 72 to 60 because of to a person of the shader engines getting disabled. The “Activity Clock” has also been dropped down to 1815MHz with the Raise Clock down to 2105MHz.
Even with that, the Radeon RX 6800 will however have the whole 16GB 16Gbps GDDR6 memory and 128MB Infinity Cache. And since it’s a bit slower, the board electrical power has also dropped down to 250W rather.
The 6800 will primarily contend with the $499 RTX 3070, even even though it can be a lot more high-priced. AMD claims in its charts that the 6800 is speedier than the RTX 2080 Ti, which has related concentrations of performance as the RTX 3070. Nevertheless, we would just take this chart with an even greater pinch of salt as it can make use of a function named Smart Entry Memory, which we will focus on shortly.
And lastly, there is the flagship Radeon RX 6900 XT. This $999 graphics card will come with the entire enhance of 80 compute models along with the exact match and improve clock speeds as the 6800 XT. The relaxation of the technical specs are equivalent as effectively.
AMD determined to get a swipe at the lofty $1499 RTX 3090 with the 6900 XT in its comparison charts. This time, nonetheless, we would advise a smaller teaspoon of salt as these results are taken with Intelligent Accessibility Memory and one thing called “Rage Method” enabled.
So what is this comically named Rage Manner? AMD phone calls it a 1 click overclocking remedy. According to Gamers Nexus, Rage Manner unlocks the ability targets on these cards so they can clock bigger. It would not essentially overclock the card by itself, just gets rid of some of the electricity constraints that could avert it from clocking higher in some cases. For manual overclockers, this is practically nothing new but those who are both new or uncomfortable with overclocking can just click on this just one button and hope it does something.
As for the aforementioned Good Accessibility Memory, this one’s a little bit far more interesting. For this to function, you need to have a Radeon RX 6000 sequence GPU, a Ryzen RX 5000 series desktop CPU and a 500-sequence chipset motherboard. As soon as you have this trifecta and help an alternative in BIOS, it lets the CPU obtain to the comprehensive 16GB VRAM on the graphics card, which supposedly decreases memory fragmentation on the VRAM and enhances effectiveness.
Within AMD’s exam samples, they say anywhere from solitary digit to small double digit gains in efficiency with Rage Mode and Good Obtain Memory enabled on the 6800 XT.
RDNA 2 also features assistance for Microsoft’s DirectX 12 Best API. This permits assistance for features like components-accelerated ray tracing, variable rate shading, mesh shaders, and sampler feedback, functions that were being beforehand only obtainable on choose NVIDIA GPU.
Ray tracing will probable be the a single most ended up hunting forward to. AMD announced a handful of titles that will be available shortly that guidance ray tracing on AMD cards, despite the fact that technically almost nothing really stops the present titles this sort of as Regulate, Metro Exodus, Battlefield V, and so forth. from doing the job on RDNA 2 hardware because they are all centered on Microsoft’s DXR implementation. It will be up to AMD to permit aid for them in its drivers. At some point, all DXR based mostly titles should really perform on all RTX, Radeon RX 6000, and Xbox Collection X|S components.
AMD is also supporting the Microsoft DirectStorage API, which aims to boost load moments and boost texture good quality. Along with that, the organization will go on to aid its personal technologies, these types of as AMD FidelityFX, Radeon Anti-Lag, and Radeon Strengthen.
What’s lacking from AMD’s arsenal for now is an alternative to NVIDIA’s DLSS or deep discovering tremendous sampling. This enabled AI-assisted upsampling of recreation property applying scans of high resolution property, which effects in close to native resolution picture excellent but with a reduce rendering spending budget.
AMD has promised a technology known as Super Resolution, which would seem related to DLSS but delivered no even further facts that would enable us know how very well it would perform. The characteristic is also even now in advancement and will not likely be offered for some time soon after the launch of these cards. That must place a critical dent in AMD’s ray tracing effectiveness compared to NVIDIA’s DLSS, which is most likely why AMD hasn’t introduced help for current DXR titles as most of them have some kind of DLSS.
Now for availability. The RX 6800 and 6800 XT will be accessible setting up November 18 for the aforementioned rates of $579 and $649 on AMD.com. The RX 6900 XT will be accessible starting December 8 for $999. Playing cards will also be accessible from the common board associates, these types of as ASRock, ASUS, Gigabyte, MSI, PowerColor, SAPPHIRE, and XFX in November.
