Skylake Clockspeeds and benchmarks!

Some 4790k chips pull around 1.3v at stock clocks. 4ghz is quite high for a stock speed and turbo.

edit:

I guess 14nm should be pulling a lot less than 22nm.

The chips in the review being compared you have a 4790k at 1.1v at, a 5775c at 1.2v at only 3.5Ghz and the 6700k needing 1.3v to do that clock speed.

In general review samples have always been a bit cherry picked by Intel and I have no problem with that. But if you have three cherry picked chips to the same guy giving maybe the best(lowest) voltage chips around to make a comparison then I wouldn't be surprised if the average Skylake comes in at 0.15-0.2v higher voltage requirements.

They delays and issues with Broadwell have been known about(to varying increasing degrees) over the past 2 years because it was about 2 years ago they were officially pushing back Broadwell by a quarter(then did it again and again) and same with 14nm. Before then there was a lot of talk it wasn't going great but I don't think much talk it was going really badly(for Intel a year delay on desktop parts is considered extremely bad for supposedly the best process company in the business).

The voltage on all the previous 14nm products has been surprisingly high and with bad clock speeds to go along with them so this doesn't come as a huge surprise. However you would hope that Broadwell was effectively canned so they could move on to a 'fixed' Skylake where high voltage/temps wasn't an issue and higher clock speeds would be possible.

Thanks! I think I will just go for the 3770K and overclock it. I have never ever overclocked in my life!

My cooler is "SUPER QUIET 22dBA TRIPLE COPPER HEATPIPE CPU COOLER"

Will this be enough?

I'm guessing it is a custom pre-built PC? It depends what that actually is.

But that would be worrying if the cherry picked Skylake has 1.3v at stock? I'd hope that it is just one of the higher voltage chips.
 
That would be the point, yes. If it's a cherry picked sample then it's likely most are higher voltage. Trouble is basically everything done on 14nm so far has been higher voltage than the previous node at a given clock speed, quite a bit higher really.

Yes it was a custom PC I specced myself. Not really sure what kinda cooler it is... how much would a good one cost to pair with a 3770K?

Coolermaster Hyper 212 Evo sets you back around £25 and it's arguably the most commonly used, aftermarket CPU cooler there is.

Well, looks like the 5820k may well be my next upgrade going by that first review.

This.

The 5820k really does seem like it could be the better long term purchase for a lot of people.

Regardless of the benchmarks turn out like skylake will be a big hit for people want a powerful cpu for small cased gaming setups.

Personally looking forward to seeing how the mobile skylake cpu's perform.

Yup same. Similar price for processor, £50-£100 extra for the mobo depending on what bells and whistles you want, similar price for the RAM.

For that you get slightly worse single core performance, 150% of the cores and 150% of the threads. Win win for longevity in my opinion.
 
The cinebench score of 930 at stock are promising - I don't trust those gaming results though, waiting for the Anandtech review tomorrow for those :)

All I can say is that I'm glad DDR4 is dropping a considerable amount.

It's actually going back up due to Samsung winding back production to artificially control the price. ****s.

So not only will we be expected to buy a new socket with less performance but also get rinsed on RAM. Nice.
 
Early bios issue perhaps regarding the high voltage? At release, devils canyon chips were suffering from very high voltage (1.300+ being pretty much the norm) due to bios issues on boards. Average voltage for most 4790k's after a bios update was about 1.2v.

Spot on. Anyone on a CPU 2500k onwards is just wasting money buying one of these for gaming. The difference won't even be noticeable, AGAIN! Really need some competition in the CPU sector. People say nVidia milk their customers but at least you can see a decent performance increase every generation, Intel are the real kings of milking.
 
forgive me for being stupid whats the difference between skylake and skylake-s? im too lazy to look it up

theres no real point in upgrading but its always nice to have new tech

Skylake is a family name for Skylake-S/H/U/Y.
From these the Skylake-S is the one we're waiting for, since it's the upcoming K-series CPUs.
