Amd 6800 xt9/23/2023 ![]() But a lot of the underlying changes don't show up as an easily digestible number.įor example, AMD says it reworked much of the architecture to focus on a high speed design. There are other tweaks to the architecture, like support for 8K AV1 decode and 8K HEVC encode. ![]() Support for ray tracing is probably the most visible new feature, but RDNA2 also supports Variable Rate Shading (VRS), mesh shaders, and everything else that's part of the DirectX 12 Ultimate spec. Memory capacity has doubled, ROPs have doubled, TFLOPS has more than doubled, and the die size is also more than double. ![]() Clock speeds are also higher, and - spoiler alert! - the 6800 series cards actually exceed the Game Clock and can even go past the Boost Clock in some cases. AMD has just about doubled down on every important aspect of its architecture, plus adding in a huge amount of 元 cache and Ray Accelerators to handle ray tracing ray/triangle intersection calculations. When AMD fans started talking about "Big Navi" as far back as last year, this is pretty much what they hoped to see. With the arrival of Ryzen 5000, running AMD GPUs with AMD CPUs finally means no compromises. We've added more benchmarks on both Core i9-10900K and Ryzen 9 5900X. We've got our standard testbed using an 'ancient' Core i9-9900K CPU, but we wanted something a bit more for the fastest graphics cards on the planet. If you're just here for the benchmarks, skip down a few screens because, hell yeah, do we have some benchmarks. If you want to know more about the finer details of RDNA2, we'll cover that as well. Now, it's time to take all the theoretical aspects and lay some rubber on the track. We've previously discussed many aspects of today's launch, including details of the RDNA2 architecture, the GPU specifications, features, and more. ![]() How do AMD's latest GPUs stack up to the competition, and could this be AMD's GPU equivalent of the Ryzen debut of 2017? That's what we're here to find out. AMD also finally joins the ray tracing fray, both with its PC desktop graphics cards and the next-gen PlayStation 5 and Xbox Series X consoles. Big Navi, aka Navi 21, aka RDNA2, has arrived, bringing some impressive performance gains. ![]()
