New AMD RDNA 2 graphics chip is spotted in the wild in the hands of engineers and custom cooling AIB (Add-In Board) partners. Upcoming Sony PS5 and Microsoft’s Xbox Series X/S also support RDNA 2.0 architecture with Ray Tracing enabled graphics. According to prominent tech enthusiast _rogame from twitter, the latest leaked chip performing at AOTS (Ashes of the Singularity) benchmark belongs to Navi 22 GPU and not Navi 21 which majority tech enthusiasts claim it’s a RX 6900 XT.
Surprisingly, average frame rate performance of possible RX 6700 XT matches RTX 2080 Super GPU from Nvidia. Whopping 63.9 fps produced by Navi 22 chip at crazy presets with 4K resolution and successfully beating old RTX 2080 vanilla edition by 20%. Potential ultimate performance of RX 6700 XT is not identified yet since optimizations are still ongoing. However, the naming scheme of RX 6700 XT is rightly guessed by twitter user MMilf3 due to 30% superior performance metrics over RX 5700 XT suggest that new AMD card must be 25-30% according last year’s AMD presentation slides. As you see, Radeon RX 5700 XT is 25-30% faster than old GCN architecture based Vega 64 GPU in latest games.
Great part of RX 6000 GPUs is PCIe 4.0 native support for wider bandwidth to eliminate memory and CPU connection bottlenecks. For some unknown reason i9-9900K is used for testing with limited PCIe 3.0. For sure, it could bottleneck Navi 22 GPU by using narrow bandwidth. Latest RTX 3000 series lineup are supporting PCie 4.0 too. Definitely, you can squeeze out of RX 6700 XT some little bit of performance in 4K resolution using Ryzen 9 CPUs.
