I have some water cooled Xeon Gold (6100 series) chips. Generally they never throttle, unless running a code well known for heavy use of AVX 512.
So despite running many codes that use all cores 100%, using AVX512 is the only way I've seen them throttle.
- janwas 4y agoThanks for the data point. Water cooled, impressive. But what is the problem here? Power is work per time. More power can be a good thing, especially if the work is useful. This is more likely in the SIMD case, which has much lower OoO cost than scalar code in terms of total work accomplished. At some point, the chip hits a limit and throttles. This means less speedup than otherwise might have been the case, but it's still a useful speedup relative to scalar, right?
