AMD Radeon RX 6400 benchmark results leaks: 30% slower than the RX 6500 XT
AMD released the Radeon RX 6500 XT/RX 6400 at CES 2022. The new graphics card is based on the Navi 24 core, manufactured using a 6nm process, and equipped with 16MB of unlimited cache. Radeon RX 6500 XT will be configured with 16 CUs and have 1024 stream processors, while Radeon RX 6400 has only 12 CUs and 768 stream processors. Both graphics cards will be equipped with 4GB of GDDR6 memory with a 64-bit memory width. The Radeon RX 6500 XT is already on sale, and according to AMD, the Radeon RX 6400 should be limited to the OEM market.
The Radeon RX 6400 has recently appeared on Geekbench and was tested with the Windows 11 operating system on a platform based on AMD Ryzen 5 5600X, ASRock X570 Taichi, and 32GB DDR4 memory. ASRock had previously submitted a product called RX6400 CLI 4G to the Eurasian Economic Commission (EEC), which may be its retail version.
From the benchmark results, the Radeon RX 6400’s Vulkan score is only 7% lower than the Radeon RX 6500 XT, but the OpenCL score is nearly 30% lower. The PCIe 4.0 interface of the Radeon RX 6400 is also only four-lane, plus it does not support 4K H.264/H.265 encoding and AV1 decoding, I believe it is still very attractive for users of old platforms using PCIe 3.0.
