Kaby Lake i7-7700K power efficiency...

[Raja@ASUS]

Hah, yeah I mean CPU + Mobo, total typo. I think it's no mystery that the Kabylake is more efficient, but by how much is still a mystery. (I'm not getting a Skylake now, I don't get paid by Intel or Asus

But the point is in scientific experiments, you should compare apples to apples wherever possible. This is not about anybody getting personal or ego's, it's just reality.

Cheers.

Interesting back-peddle, I mean typo, er I mean motherboard, no, I mean GPU, or maybe Z170/Z270.

Yeah, even the "motherboard" isn't really part of it; it's just the VRM efficiency. Motherboard implies "a lot" of power circuits. The rail distribution is the same across boards (only the main power rails for CPU power connected to EPS12V). Now, if I was measuring stuff like most other people do (wall power etc), more variables would be in the equation, and I'd be inclined to go further. See no need to go that far here, though, even if it doesn't jive for you.


I'm usually very scientific, just in this case, I dont mind putting my name against this without going that far - seen enough to know and that's enough for my peace of mind. However, if it's disturbing yours, well, you know what you can do about it. I always encourage people to learn for themselves.

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.
