There's no denying that Intel's Core i9-14900K is a power hog. This article examines the power, performance and thermals effects of limiting its power consumption, with very interesting results. Additionally, we investigate undervolting to determine if efficiency can be optimized even further.
U and T chips rule this chart https://www.cpubenchmark.net/power_performance.html and that’s what this test shows too: the 35W version obliterates everything on the desktop efficiency wise. Ironically, it’s even more efficient than the E core only N100.
It’s quite interesting to see this in light of https://benchmark.chaos.com/v5/vray?index=1&ordering=desc&by=median&my-scores-only=false – on server platforms AMD is way more performant. Perhaps Intel’s core doesn’t scale as well up as it does down?
