AMD Radeon vs. Intel Arc Graphics With Linux 6.2 + Mesa 23.0

When running the demanding GravityMark cross-platform, cross-API benchmark, the Arc Graphics A770 at 1080p with Vulkan was coming right between the RX 6600 and RX 6600 XT. The Arc Graphics A750 was coming up just shy of the RX 6600.

The AMD RDNA2 graphics cards were delivering better performance-per-Watt under Linux with the Arc Graphics cards having similar power use to the RX 6700 XT.

For GravityMark at 1440p with Vulkan, both the Arc Graphics cards were running between the RX 6600 and RX 6600 XT... But when it came to the power efficiency, they were trailing the AMD Radeon RX 6000 series.

The Unigine Heaven OpenGL results show that the Intel Arc Graphics A750/A770 can actually perform admirably well when the driver is operating in an optimal manner. With Unigine Heaven these Intel graphics were performing between the RX 6600 XT and RX 6700 XT graphics cards.

But the A750/A770 cards were also consuming the most power during these benchmarks.
