AMD Radeon RX 7900 XTX OpenCL & Vulkan Benchmarks Leak Out

AMD Radeon RX 7900 XTX graphics card benchmarks have been leaked within Geekbench 5’s OpenCL & Vulkan performance tests.

AMD Radeon RX 7900 XTX Geekbench 5 OpenCL & Vulkan Benchmarks Leaked, Requires Optimized Drivers

The performance benchmarks were leaked within the Geekbench 5 benchmark and showcase the OpenCL & Vulkan performance of the upcoming graphics card. Based on the benchmark numbers, we can see that the AMD Radeon RX 7900 XTX graphics card isn’t using optimized drivers since the performance is slower than the RX 6900 XT (RDNA 2). The RDNA 3 graphics card is said to be up to 60-70% faster than the Radeon RX 6950 XT so one should expect much better performance when the final drivers drop.

Finally, we have the Vulkan benchmarks where the NVIDIA GeForce RTX 4080 graphics card ends up being only 5.5% faster than the RTX 3090 Ti, 20% faster than the RTX 3080, and 45% slower than the RTX 4090.

AMD Radeon RX 7900 XTX 24 GB Graphics Card “Official” Specifications

The AMD Radeon RX 7900 XTX graphics card utilizes the full Navi 31 XTX GPU which features a total of 48 WGPs, 96 CUs, and 6144 cores. The core clock for the graphics card is maintained at 2.3 GHz base clock and 2.5 GHz boost clock, delivering up to 61 TFLOPs of compute performance at a 355W TBP.

AMD Navi 31 XTX: 6144 Cores, 384-bit Bus, 192 MB Infinity Cache, 308mm2 GPU Die @5nm
