AMD Radeon RX 7900 XTX OpenCL & Vulkan Benchmarks Leaked

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

AMD Radeon RX 7900 XTX Geekbench 5 OpenCL and Vulkan benchmarks leaked, require improved drivers

Geekbench 5 benchmarks leaked showing 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 does not use optimized drivers because 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 being slower with a score below the 100K barrier. That’s 20% slower than the AMD Radeon RX 6900 XT graphics card and again, we’ll blame the early drivers or no (at all) drivers for this result. We can also see the card boost up to 2270MHz which is well below the peak boost clock of 2.5GHz.
