Hold your horses, Core i7 6700K @ 5.2GHz (1.35V) on air cooling! 🙂

A good first preview. It's probably a cherry-picked chip like the i7-5775C they showed @ 4.8, but even if that is the case, 5 GHz @ 1.35v is better than 4.8 GHz @ 1.42v, at least until you take eDRAM into account. Then maybe it isn't.

Fugger had to push 1.55v to reach 4.8 GHz with his 5775C ES, so the 6700k will more-realistically require maybe 1.45v-1.50v for 5 GHz. Fact is, the clockspeed wall can be breached with some voltage, which is good. We'll see how long those chips last with that kind of voltage if people start nuking their lurvely i7s.

Looks like 5.2 Ghz to me.

Cherry picked or not, 5.2GHz @ 1.35V is indeed better than Broadwell-K's 4.8GHz @ 1.42V. Should be a fun chip to play with and a worthy Haswell successor.

I do think Core i5 5675C is a great option for those keeping their LGA1150 boards and DDR3 kits though, what Intel needs to do is improve retail availability.

i5-6400T in this leak scores 16-18% higher in both GPU tests.

So the slowest 35W TDP Skylake-S (ES) most likely running non-final drivers outperforms 84W TDP Haswell. Nice.

More critical is the voltage. You know, even with the improved version of the grease 22nm Haswell Core i7-4790K, was trying to 5.1-5.2GHz need 1.5-1.52V high pressure. I believe that if at this voltage, i7-6700K can run more violent!

For what it's worth, John Lam's comment @ HKEPC's Forums (poor translation):

I measured, 5.2GHz Max, 5.0GHz Super Pi 32M about 1.32v, 5.1GHz to 1.38v

If that's true, then I am hopeful for Skylake-E clocking well also. Around 5ghz with a hex core Skylake? That would be so legit.

While I'll fully agree that expecting any i7-6700k to hit 5.2 GHz would be overly optimistic... SKL overclocking being markedly better than anything since SNB wouldn't be surprising in the least. For one thing, recall that SKL is a Tock from Intel's Haifa design team just like SNB, whereas HSW was done by their Oregon design team. That's not saying that one team is better or worse than the other on the whole, rather a mere suspicion that the Haifa team may well design in more margin on the timings which would result in better overclocking capability.

Cool info. I've always been a sucker for this stuff. I used to really follow which team was on which core, I assume the Haifa team is the Israel one? I remember the Oregon team being in charge of the big stuff like Nehalem and then the Israel team always followed suit with more efficient stuff.
I personally always thought that it mattered what team was working on the chip, and that one was possibly not better overall, but better in certain areas than the other one and vice versa.

Like when the Israel design team dropped banias (Pentium-M), it basically set the precedent for the future Intel design goals. It was the 1st generation of the Centrino laptop ecosystem the seed for Conroe, and more efficient chips then netburst in general.

Those were the good ol'days~ Here's hoping skylake brings some innovation~

Exactly. I'd say the best way to put it is that they each have their own design goals. The saga of the FIVR is a good example of such - the Oregon team went that route because of its numerous advantages in the pursuit of power efficiency, whereas the Haifa team took another route to improving efficiency.

This could be a really ignorant question, but is there someone above them (i'm sure there is) that these teams need approval from? Or is there someone guiding them or giving them design goals to achieve? The FIVR saga makes me wonder that because it seems like they can make these decisions for themselves?

Like is there someone going "hey we don't want you doing that, we want this instead" "or thats too far down that path, come back this way a little more"

Marketing/OEM feedback.

I could see it now:

Intel: So we are removing the FIVR in Skylake.
OEMs: zzzzzzz... What was that again?
Intel: Also we are encouraging wireless charging in the laptops.
OEMs: YAY!

And later..
OEMs: Why the Laptop industry died and why there are way more tablets than before?

Reviewers getting their hands on Z170 LGA1151 motherboards and Skylake-K (Core i7 6700K & Core i5 6600K). Expect reviews around Gamescon in early August.

Do you guys think the yield problems Intel is experiencing with Broadwell will force them to delay Skylake?

No.

That's kind of irrelevant. The point is they claimed 9 hours battery in the beginning but later they lowered it to 7.2 hours. And guess what? They were very quiet about the 7.2 hours. The article is merely proof of that.

Not better than HD 4600 in 3DMark11 though. Its about equal.

Remember the world overclock records for 4790K and they made it sound like it can reach 5GHz pretty much? Well the actual samples fell little short of expectations.

Then there's the "4.8GHz Broadwell ES = 4.2GHz real Broadwell".

I think that the big improvement is at very low power, explicitely within 4-4.5W TDP.
Click to expand...

Not even. 4-4.5W TDP is probably double the clock of what 14nm benefits from.

The most optimistic of Skylake I've heard was that Core M version will be 30% faster than the Core M in Yoga 3 Pro, which means if its true it'll merely be living up to the fanciful expectations hyped by the Broadwell Core M slides and reference machines.

If that's because Skylake allows much better sustained Turbo clocks, that doesn't bode much for 6700K since there's no real room for Turbo neither it has higher clocks than 4790K.

When will it be possible to buy them. Will the Skylake launch be like the Broadwell launch or will they actually on or around August 5? Reviews on Broadwell have been trickling out for over a month and a half now and not a single CPU to be had at retail in most of the world.

The point is, that there were much better implementations of core M.
