AMD Radeon RX 9070 Series Linux GPU Compute Performance
To some surprise, the Radeon RX 9070 series outperformed the GeForce RTX 5070 competition with the IndigoBench OpenCL renderer... But there wasn't much uplift from the RX 9070 to RX 9070 XT and these RDNA4 graphics cards remained slower than the previous generation Radeon RX 7900 XT. The performance is also a bit odd with the RX 7900 GRE trailing behind the RX 7800 XT, for example. On a performance-per-Watt basis with IndigoBench, the Radeon RX 9070 was best positioned on the AMD side but trailing behind the NVIDIA RTX 40 / RTX 50 graphics cards in power efficiency.
It was nice seeing OpenCL working at least on the Radeon RX 9070 series with really not knowing what to expect given the lack of ROCm information pre-launch.
With some OpenCL benchmarks, the NVIDIA performance remains much better than the equivalent AMD Radeon graphics cards. In the S3D benchmark,. the Radeon RX 9070 XT was only matching the RX 7900 GRE.
When looking at the global memory bandwidth performance, the RTX 5070 with its GDDR7 video memory came out well ahead of the RX 9070 series with its GDDR6 video memory.
There were also some oddities such as the RX 9070 series single-precision compute performance within clpeak performing very poorly on the Radeon RX 9070 series.
