Skylake - let's wait and pray for it together

Here is finally some testing on overclocking: http://www.computerbase.de/2015-06/intel-core-i7-5775c-test/5/

5775C can do 4.1 Ghz at stock voltages, but that's about it and it was unstable at 4.3 Ghz with 1.35 volt. So that's it, since Broadwell at 4.1 is slower than Haswell at 4.4, there is no reason to get this CPU for a desktop PC.

Also they write that Intel told them that Broadwell CPUs are NOT targeted towards overclocking and nothing more than 4.2 ghz should be expected.

 

It took them 1.2v to get to 4.1GHz. Stock voltage for that chip appears to be around 1.0v. It's all in the screenshots if I'm interpreting them correctly.

Maybe the voltage was set to some kind of "auto" setting. If so, then the auto voltage was probably higher than it needed to be. Maybe those kinds of settings have improved in the past few years, but I always thought that auto voltage settings were unnecessarily conservative.

 

The first screenshot is when they undervolted. Learn2deutsch.

 

There's no way in hell 1.2v is stock for a 14nm chip. How are they even doing that?



I thought ~1.1v was roughly the stock load core voltage for most 22nm desktop CPUs. There's no way in hell that they are moving backwards with 14nm.

 

Skylake K will be presented between 6th and 9th of august.

A little over two weeks to go for the release, are you excited children? I am.

Just look at this nice overclock:

 

From FanlessTech: "EXCLUSIVE: The Skylake boost."

Skylake improvements compared to Broadwell:

• Y-series: up to 17% faster CPU, up to 41% faster GPU, up to 1.4 hours more battery life
• U-series: up to 10% faster CPU, up to 34% faster GPU, up to 1.4 hours more battery life
• H-series: up to 11% faster CPU, up to 16% faster GPU, up to 80% lower silicon power usage
• S-series: up to 11% faster CPU, up to 28% faster GPU, TDP decrease from 84 W to 65 W

 

Yeah we will see how this works out, the desktop chips would be the S series and they get plus 10% over Broadwell, which would mean +15% over Haswell. I can't be that optimistic anymore.

But I will get an unlocked chip no matter what on the 5th of august. The only question is i5 or i7, paying 120€ more for hyper-threading does not seem worth it.

Stay here iMac, stay in this thread forever, you won't leave me too like Spartacus, will you?

 

So if you want your Skylake CPUs, you better order them right when they get released on the 5th or else you might wait some weeks for more stock:

Sounds like I'll be investing in my storage and GPU this month (or perhaps I should stockpile?)

 

I will get an i5 6600k once I know that I can get a proper z170 board without weird gamer shit on them. I just want a board with not too many phases, intel LAN, Realtek audio, 1x PCIe 3.0 16x, 2x PCIe 4x and normal sata or sas ports. Only saw gimmiky gaming shit get announced so far. I want reliable shits.

 

So no hyperthreading for you mate? I see, I see. What DDR4 RAM will you get, just the cheapest that is available? ASUS will sell a standard Z170-A board soon, that should fit for you.

 

Kingston HyperX Fury DIMM Kit 16GB, DDR4-2133, CL14-14-14 (HX421C14FBK2/16)

Asrock has their first 4 boards listed on geizhals since yesterday, but I hate Asrock (and XFX and GALAX and ...) but those give not quite the choices I want. It at least gives a hint where prices will be.

I assume the 6700k will be around 410 EUR, so the 6600k should be ~ 320 EUR. Still complete guesswork, looking at the horrendous pricing for high end Haswell-refresh CPUs in germany.

 

Wait wait, 200€ for the motherboard and 400€ for the chip? That better not be true, I'm expecting same prices as for the 4790K. (100€ + ~320€) But I love how cheap DDR4 finally got, gonna make the jump from DDR2 straight to DDR4. Not going for something fancy probably, since there shouldn't be any notable performance difference.

For general education:

Intel CPU prices are heavily tied to the exchange rate and importers deals for bulk amounts (10 thousand CPUs vs 200 thousand CPUs).

Have a look how pricing for the 4790k went so far:
http://geizhals.de/?phist=1119923&age=9999

Concerning RAM, I just want proper throughput. So a slightly lower CL and slightly higher bandwidth should be fine. Those sticks with insane OC bandwith are generally shit and overpriced. There was some in dept article on Toms Hardware a while back (cba to search it now).

EDIT: the former listed Asrock boards are now gone from the site and the dealers

EDIT2: Other people are also guessing prices. 375 EUR for the 6700k and 261 EUR for the 6600k could be reality.

 

Yeah, that's the reason I didn't buy a Haswell chip, can't be bothered to pay more for an even older technology. But I have seen new 4790Ks for 300€ at eBay, if it's 375€ vs 300 only to get 5% more performance and some energy savings then I don't see the point in Skylake.

 

Dat design:




Comes without cooler:

 

OMG, prices are out and they are the same as for Haswell!



http://benchlife.info/wp-content/uploads/2015/08/skylake-price-1.jpg

They should cost 1.1 times the dollar price in euros (with tax). So ~340€ for the i7-6700K and 240€ for the i5-6600K.

 

-Aida64 has updated to support Z170 and Skylake. (Old Chili Keygen still works)

-the K CPUs ship without a cooler: Keep 6 year old Megahalems (with old O-rings) and get an adapter kit or change to a less fiddly cooler?

Wishlist to keep track of my upgrade: http://geizhals.eu/?cat=WL-567551&wlkey=a27936fe761514f8fa175a653ba95cdd
