AMD Radeon RX 7900 XTX Geekbench 5 OpenCL & Vulkan Benchmarks Leaked, Up To 20% Faster Than RTX 4080
Update: New benchmarks have now been published within Geekbench 5 which showcase far better performance numbers. The RX 7900 XTX sits 8% below the RTX 4080 in OpenCL & 20% faster than the 4080 in Vulkan tests.
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 AMD Radeon RX 7900 XTX ends up 20% faster than the RTX 4080 and 57% faster than the Radeon RX 6900 XT graphics card. We can also see the card boosting up to 2270 MHz which is far below its peak boost clock of 2.5 GHz.
