Blender 3.4 HIP Performance With Radeon RX 7900 Series + RDNA3 OpenCL Compute Benchmarks

Lastly is a look at various SHOC OpenCL benchmarks for the NVIDIA and AMD graphics cards tested. For a number of the tests the RX 7900 series OpenCL performance was coming in short of expectations while a follow-up article will look further at this to see if it's the Radeon OpenCL driver or if using alternatives like the in-development Mesa Rusticl OpenCL implementation can help further along the RDNA3 compute potential. Basically whether it's a software or hardware bottleneck currently being encountered... But on a positive note, at least there is this working HIP and OpenCL support for RDNA3 on launch day.

As one positive point, across all of the OpenCL compute benchmarking, the Radeon RX 7900 series did tend to lead in the best power efficiency and overall the power consumption of these new RX 7900 XT and RX 7900 XTX graphics cards was lower than even the GeForce RTX 3080/3090 series.
