With the varying state of OpenCL across vendor drivers, it's with clpeak where the ROCm OpenCL was working out fine but in turn the NVIDIA driver was failing to run clpeak. When looking at the global memory bandwidth measured by clpeak, the Arc Graphics A750/A770 was delivering 1.27x the bandwidth of the RX 6700 XT.

For clpeak's single precision compute measurement, the Arc Graphics A770 was 14% faster than the Radeon RX 6700 XT while the Arc Graphics A750 was matching the RX 6700 XT.

On a performance-per-dollar basis, the Arc Graphics A750/A770 compete very well against AMD's lower-end RDNA2 parts.

The Arc Graphics hardware with this latest Intel Compute Runtime was also performing very well against the Radeon competition when it came to integer compute performance.
