Stability was fine, power use was slightly higher than the 6650 XT card I tested (both are third-party designs so they can vary a bit). I do need to get the full review out the door at some point!
Let's see...
Sapphire RX 6700:
194.1W FurMark, 192.4W Metro Exodus
36.8 dB(A) noise at 10cm, so nearly silent, 58.1 dB(A) at 75% fan speed setting.
So yeah, it's very much a "slightly better than 6650 XT, ~10% worse than 6700 XT" sort of thing. I'm going to retest everything on the 13900K test system in the coming weeks, which may change the results slightly. Basically, the 6650 XT numbers are slightly old and may or may not reflect current performance. Also, several games have had patches that altered performance quite a bit, and I don't know precisely which versions were run on which GPUs. Stay tuned for GPU benchmarks hierarchy, 2023 edition!
