It is a little funny. People have been complaining for
years about both AMD and Intel (along with motherboard vendors) pushing their silicon to the ragged edge out of the box and sacrificing both efficiency and thermals to squeeze out every last point from launch day benchmark results. Yet we're seeing today exactly why that's been the case. Any talk about power efficiency and much-improved thermals is buried under an avalanche of relatively underwhelming performance benchmarks. I doubt AMD (or Intel) will make this mistake again.
That Anandtech test is using the 7700 non-X, not the 7700X. The former is a 65W part with a lower power cap. The 7700X is a lot more power-hungry out of the box.
