[Benchlife] Intel Kaby Lake Mainstream Quad Core Landing in December This Year - Page 4

post #31 of 106
Is there a comparison between i7 quad cores (i7 920, 2600k, 3770k, 4770k, i7 6700k) where they're all tested at the same clockspeed?
It sounds like something that would have been done before but I haven't seen anything like that so far..

I would say getting a cpu now wouldnt make a different if you wait...



I really dont wish to pin any hope on this new cpu.



1) No guarantee it will go 5GHz 24/7 stable

2) No guarantee it will be out this year for K model.

3) No guarantee there will be any IPC improvement.

Until AMD gives Intel competition, it will still be quad.

Kaby Lake IPC would not increase over Skylake at all, would it? This is "optimization" which is neither a process shrink nor a microarchitecture change. We already saw this when Haswell Refresh was introduced - just a minor clock rate bump.

When Intel talks of xx% performance increase at the same TDP, then that's the keyword, "same TDP". Meaning that improved energy efficiency allowed them to squeeze a bit more performance out of the same power envelope. Presumably due to 14 nm process becoming more mature and refined.

That likely works only for ultra-low TDPs anyway, and does not translate into the same performance gains for desktop parts.

Very small comparison similar to what you are looking for

Just ignore him. I went on an ignore spree recently and these forums are way more enjoyable. Shame that you still get to read people on your ignore list through quoting.

I simply refuse to purchase another quad core cpu from intel, its way overpriced and they keep giving us the same crap each year. 6 core needs to be the standard or bust.

But Haswell 22nm to Devil's Canyon 22nm increased the TDP in order to get more clocks ( and thermal paste ) whereas Skylake 14nm to Kabylake 14nm increased the clocks at equal TDP
