[WCCF] Intel Skylake 2015 Platform Details Revealed

[CHADBOGA]

Intel is moving the K line to the best IGP. The cynic in me suggests that this is an attempt to justify raising the price. Broadwell-K will be 4+3e, Skylake-K will be 4+4e, etc.

Would have thought that the more expensive the CPU, the less you care about IGP, on the desktop.

Maybe for Apple? Anyway, it might make for a nice SFF light gaming PC. Will be interesting to see what the e-dram versions can do with a full desktop TDP. The problem, as you say will be the cost. If they sold Broadwell K with the edram at the same price as Haswell K that would be a deal, but doesnt seem likely.

Overall though, I dont really understand. I would bet nearly every one of the K processors will be used with a dgpu.

The extra compute power and the edram would be nice at least.

Nope. Us old farts don't game that much. I'm using 2 i7's with built-in graphics that are finally Good Enough: i7 4770k and i7 4790k.

BTW, I still think there is going to be a 'Skylake Refresh' type part in 2016 and you won't see much (or any) 10 nm Core until 2017. Even if it's just clock speed tweaks and the return of the FIVR.

Cannonlake won't have FIVR. That's Icelake, the one after.

So, what was so wrong with FIVR they are ditching it with Skylake and what's going to be so great that they are putting it back with Icelake?

Politics, apparently. The Haifa team had some issues with it. Icelake is back to Hillsboro, so FIVR comes back with it.

Wish I could find the link that tells the story a bit better.

Why they removed FIVR...

FIVR is like HT.

Came in P4, vanish in Core 2, back in Nehalem for good. Not sure why they do it that way. Must be some kind of field trials.

Well Core 2 was the successor to Core. It would have showed up, at least in mobile, even if Intel had stuck with P4.

Thanks for the responses, guys. Knowledge is power :thumbsup:

EDIT: Does that mean, that in lower/idle power states, Skylake might be not as efficient? I see my 4770K sometimes consuming very close to 0 mv.

What is the original source of that slide though? Although it looks like an intel slide, I cant imagine them making a statement which basically implies Haswell and Broadwell dont scale well to higher power configurations.

It would be nice though if Intel is in fact devoting a generation on two toward increasing performance more in the higher power configurations.

User mikk posted it. He says he removed the source's name/watermark to avoid getting said source in trouble.

I believe that these slides are legit.

I keep reading that there is new stuff for this arch. Is this a complete new redesign or refinement on Broadwell like the previous gens?

Haven't seen any credible information. Probably the latter, though.

It's a Tock, so there will be lots of CPU and GPU architectural changes to provide new functionality, features, power and performance improvements, but that doesn't tell anything about how those changes will affect benchmarks, though.

I do think eDRAM will become a bit more mainstream with Skylake.

 

[jaydee]

No it doesn't mean that. There are three TDP ranges for the 4+2 SKL-S according to Roadmaps: 35W, 65W and 95W. Keep in mind TDP could differ.

Could you expand on this? 'S' has meant lower wattage/clockspeed (but not as low as 'T') LGA. Are these roadmaps official or leaked?

It actually makes business sense to "gimp" Skylake by limiting it's TDP, thus pushing enthusiasts towards Broadwell. I would suspect them both to have similar CPU performance anyway. Most enthusiasts a) don't care about GPU or b) will buy a discrete card.

 

[ShintaiDK]

Skylake-S got nothing to do as such with the S/T models on SKUs.

Skylake-S=Xeon/Desktop. (LGA1151)
Skylake-H=High performance laptop. (BGA)
Skylake-U=Laptop. (BGA)
Skylake-Y=Come M type ultra mobile/tablet. (BGA)

 

[mikk]

Exactly. Skylake-S refers to the package. And we have Skylake-S 4+2 Roadmaps with TDP of 35W, 65W, 95W.

You're saying those codenames have nothing to do with the following CPU models:

i5-4440S 65W TDP desktop
i5-4200H 47W TDP High perf laptop
i5-4200U / i5-5200U ~18W TDP Low voltage laptop
i5-4210Y / 5Y70 ~5-11.5W TDP ultra-mobile/tablet

Haswell 'K' is unlocked CPU, and so we have i5-4690K CPU
Broadwell-K is coming, and we expect those to be unlocked as well

What am I not getting?

You also forgot the T and M SKUs. And HQ and MQ for that matter.

There is no link between the Skylake-S codename and S model SKU beside that S models actually comes from the Skylake-S series.

Skylake is just ~3-4 months away if we're to believe the latest info, and still nearly no details are known about it. No uarch or iGPU details from Intel at all. Not even any leaks about SKUs. What's up with that?

Broadwell was the same. AMD and Intel have both kept quiet up until their product launches.
