The 5600x -> 7600x generation went backwards, dramatically, in power consumption though. The way that I look at, in two generations, we got an 82.9% increase in performance with essentially no power consumption change. That's incredible.
There are also substantial gains in areas that are not AVX accelerated - looking at Python performance, database performance, etc.
- zamadatix 2y agoThe 7600X did average 19 W higher in Phoronix's benchmark but that's certainly not the explanation for the 45% performance gain and benchmarks matching the 9x00X parts to the wattage levels of the 7x00X parts don't show perf/watt improvements, though it is nice to see saner default limits rather than eking that last 5% of perf instead. 82.9% in two generations/4 years is decent but few are disappointed with the performance gains of getting off Zen 3, they're disappointed with the performance gains of Zen 5 itself.
- eightysixfour 2y agoThe 7600x used 28% more energy than the 5600x to get those big gains. That’s not a small amount - it kept me from upgrading my SFF. My guess is that if you power limited the 7600x, the generational gains would look more linear.
