4.0 GHz base 4.2 GHz Turbo? Only other CPU that does is FX-8350.
Intel copying AMD again. D:

Is the additional TDP wasted on the iGPU?
Preliminary Geekbench results seem to indicate there's no significant IPC increase.Or the CPU cores are beefier and have significantly higher IPC, requiring more joules per cycle.
So...could you point us in the direction of pointed speculation?See? Pointless speculation.
Stop it! You're hurting my eyes! :biggrin:Preliminary Geekbench results seem to indicate there's no significant IPC increase.
Intel Core i5-6600K (Skylake, 14 nm): 3.5/3.9 GHz, 95 W TDP
Intel Core i5-3570K (Ivy Bridge, 22 nm): 3.4/3.8 GHz, 77 W TDP
Whoever said Intel is prioritizing lower power consumption over performance/frequency increase on desktop these days?
I'm seeing nearly no frequency increase, so that part is true. But I'm also seeing 95/77=1.23 => 23% TDP increase. Soooo.... lower power consumption?? Not so much, in fact the opposite...

Skylake 14nm goes from 84W to 65W.
I'm not sure where you got that from, and what "platform" means.We dont have the TDP, hence the note at the TDP. Its platform TDP.

My guess is that the voltage/frequency curve is steeper for 14nm than it is for 22nm- giving significant power reductions at lower frequencies, but at top end frequencies it is actually detrimental. (Similar to what AMD did with Carrizo: http://cdn.wccftech.com/wp-content/uploads/2015/02/AMD-Carrizo-APU_Excavator-Core-Architecture.jpg )
20% IPC increase over HW likely?
1 or 0.
I think we should be happy if its even 10%.
Arh ye sorry. I was thinking from Broadwell. You are right in 10-15% then.
Serious computing power, yes, enough to justify a switch from Haswell 4770 certainly not, at least not for me:thumbsup:
So, assuming our thinking is right, if SKL brings >= 10% perf/clock, then a 4GHz 6700K should deliver at least the same performance as a 4.4GHz stock 4790K.
That's some serious computing power.

How much would it take you?yes, enough to justify a switch from Haswell 4770 certainly not, at least not for me
