AMD Radeon RX 6600 Linux Performance

Across the span of all the Linux graphics/gaming benchmarks conducted, the Radeon RX 6600 used for testing had an average power draw of 78 Watts and a peak of 137 Watts, aligned roughly with the 132 Watts board power specification. Meanwhile the GeForce RTX 3060 as the closest competition on the NVIDIA side had a 110 Watt average and a 160 Watt peak power consumption reported. The Radeon RX 6600 power consumption was very reasonable throughout the testing and similar to that of the GeForce GTX 1060 and not much higher than the RX 5500 XT.

While the GPU thermals are highly contingent upon the particular graphics card / AIB design in use, with this Gigabyte Radeon RX 6000 EAGLE 8G graphics card, it had a 55 degree average operating temperature across the span of all the benchmarks conducted and a peak of just 60 degrees. The EVGA GeForce RTX 3060 meanwhile also had a 55 degree average with a peak of 63 degrees.

When taking the geometric mean of all the performance benchmark results, the Radeon RX 6600 with this latest open-source driver stack came out to being 6% faster than the GeForce RTX 3060 with NVIDIA's latest proprietary driver stack. The Radeon RX 6600 also came out slightly faster than the Radeon RX Vega 56 and about 15% faster than the prior generation Radeon RX 5600 XT. The Radeon RX 6600 offered nearly double the performance of the aging but popular GeForce GTX 1060.

Overall the Radeon RX 6600 is a strong contender for those looking at a modest RDNA2 GPU that if all goes well can be found today for around $329 USD. The Radeon RX 6600 on the fully open-source and upstream driver stack showed it can take on the NVIDIA GeForce RTX 3060 and has been performing well and without any driver issues in the nearly two weeks of testing thus far. Stay tuned to Phoronix for further Linux driver testing with the RX 6600. With the "Dimgrey Cavefish" code having been upstreamed for a while now, it's largely smooth sailing on modern distributions if you are able to find this card in stock and at a good price.
