Kaby Lake i7-7700K power efficiency...

[Raja]

KBL is very power efficient. Small FFT load of the latest Prime with AVX, using ~1.35Vcore and 5GHz CPU freq with DDR4-4000 on the memory...









Sub 150W. SKL pulls more current than this at 4.7GHz.

Give it a week or two and it will be on sale.

I like when you post squiggly yellow lines Raja...always interesting...there are too few

🙂

Thanks, Arne.

How is it possible?? Technically, the architecture of SKylake and Kabylake is the same in CPU part...same 14nm process, same P-states etc. Maybe it can be based also at leakage of chip (remember this only from 32nm Vishera chips, there were 50W diffrence with same settings in 20 tested pieces)?

It's called process enhancements which lead to lower leakage at equivalent voltage and frequency. If there were no advances, Kaby Lake wouldnt clock any higher than Skylake, when, in fact, it does. The base TDP for both architectures is the same, yet KBL has a higher boost clock. That tells you right there it's more efficient. It's worth having a think about what you're posting about before you post, Michal. Or, at least bring your own measurements to the table before making these posts (citing AMD's process issues doesn't count). 😉

You right man, sometimes Im too much quickly in writing than in thinking 🙂 Thank you.
