It's basically a ceiling.

- pier25 4y agoYeah very poorly phrased on my part, sorry. Since you mentioned "up to 74% more efficient at 65W" what I meant is if the perf per watt (and hence the temp) doesn't scale linearly with the amount of work. The 7700X has about double the TDP of the 3700X but about a 50% increase in perf.
- neogodless 4y agoThat is correct. I think it's always been the case that as clock speeds increase, power draw and heat generation accelerate (diminishing returns). When you're comparing 7700X to 3700X, are you talking about performance at the same TDP limits, the same clock speed, or maximum performance?
- pier25 4y agoI'm comparing max perf and TDP.
