7700K vs. 6700K - much hotter, barely faster

Intel's next-gen Core i7-7700K gets benchmarked against 6700K

Intel's next-generation Kaby Lake architecture is nearly here, and we're finally getting some real benchmark numbers from Tom's Hardware, showing that the new Kaby Lake architecture is slightly faster, and uses slightly more power, too.


The new 7700K was tested against the 6700K in a few different benchmarks, but we'll start with power consumption. The new 7700K uses 6% more power than the 6700K at stock clocks, while it uses 4.7% more than the 6700K when overclocked (with the 6700K overclocked, too).


The only game benchmarks that Tom's Hardware ran were Ashes of the Singularity, F1 2015, Metro: Last Light Redux, and The Talos Principle - all at 1080p. The 7700K beats the 6700K in every test, but if you were playing the games in a 7700K vs. 6700K blind test, I doubt you'd tell the difference between the processors with only a few FPS difference.


But the temperatures of Intel's new Kaby Lake architecture are worrying, with Tom's Hardware noting that the new 7700K was hitting 54C under gaming loads, while the 6700K runs relatively cool in comparison at just 34C. When overclocked, we're looking at 61C for the 7700K while the 6700K hits just 48C.


Overall, the new 7700K is faster than the 6700K - but is it worth it? Tom's Hardware wraps it up with a nice bow, showing the overall performance (comparative %) against the 6700K with not-so-surprising results.

Now my question is, how much of a difference will Zen be against the current-gen chips from AMD - as that is a much stronger marketing point (generation over generation) versus the slightly higher performance, but much higher temperatures of the 7700K over the 6700K.
