Intel Developer Forum 2014

I agree, meloz, but Intel really needs a Skylake 2+3 SKU.

IntelUser2000, let's wait for benchmarks instead of wasting time questioning speculations. Don't forget that Intel will also launch a GT4e SKU.

@witeken - i thought the GT4e sku was only for skylake

Desktop will skip Broadwell, except for the unlocked CPUs.

I found this video on Youtube about Skylake, just a few seconds unfortunately: https://www.youtube.com/watch?v=-z2MrKx8iBs

 

[liahos1]

they claimed "substantial improvements" in performance and battery life with skylake.

 

[Fjodor2001]

BK was asked about BDW being 6 months late (holiday season vs spring). It's because of yields and they need partners to launch all the products (their schedule = holiday season).

Hmmm... is it yields or not? If the partners would have liked to launch earlier, could Intel provide that? In that case, is Intel intentionally delaying the release to suit their partner's launch schedule? Which one is it?

Desktop will skip Broadwell, except for the unlocked CPUs.

Just wondering, have they clarified the justification of that at IDF yet? I.e. why not make Skylake unlocked at release, and skip Broadwell on desktop completely?

Both, but yields are of course the main reason of the delay. I thought BK explained it quite well, but the video of the keynote disappeared.

No, they just did some demos with Skylake running 4k and saying it's very healthy and will bring a "gigantic leap in performance and power", and its 2H'15 launch schedule.

Everything else are rumors.

IDF — At its developer forum today in San Francisco, Intel confirmed that its 14-nm Broadwell chips will be shipping not just as Core M, but also as Core i3, i5, and i7 processors early next year.

Interestingly, the firm then revealed that its next-generation CPU architecture, code-named Skylake, will be going into production in the second half of the same calendar year [2015].

Skylake will enter production in 2015H2 - So Skylake will be a 2016 launch after all? What happened to the Skylake 2015Q2 launch that some said would happen?

Can't be both I think... Are you saying that if the partner's would have liked an earlier launch, Intel could have provided Broadwell earlier? If not, it's a pure yield issue I'd say.

It is clearly 2015: https://www.youtube.com/watch?v=-z2MrKx8iBs

An important redesign in Skylake will be that the fully integrated voltage regulator (FIVR), which was introduced with Haswell processors, will be abandoned and no longer included on the die.[4]

So it's confirmed, FIVR will be abandoned. I wonder what the reason is?

 

[Fjodor2001]

N/A

 

[liahos1]

It only says that Skylake will be available to SW developers in 2015Q1 (i.e. prototypes). I could not find anything about an actual public availability date?

Kirk Skaugen's portion of the keynote said skylake for consumer availability in 2h15 on his part of the keynote

 

[Fjodor2001]

It is clearly 2015: https://www.youtube.com/watch?v=-z2MrKx8iBs

Ok, so not 2015Q2 anymore at least? They say prototypes will be available in 2015Q1, so I guess we're looking at holiday season 2015 or so for actual availability now then?

Who knows when Skylake "desktop" will actually be released. It might only be Skylake for <5W TDP tablet/netbooks that will be 2H2015, desktop CPUs not until 2016?

Desktop Skylake likely comes first this time, as it will replace 2-year-old (by then) locked mutiplier Haswell parts. There were earlier roadmaps indicating it could be launched as soon as Q2-2015 (now it's H2/2015).

 

[IntelUser2000]

But that's not what they are doing. IMO they will clock the Broadwell K high enough that regardless of Skylake's improvements in perf/clock it won't catch up to the Broadwell K. And the Broadwell also is unlocked. GT2 Skylake won't be anywhere near GT3e Broadwell either.

Like I said before, its akin to what they did back in the Nehalem/Westmere days. They didn't want to delay node introductions artificially, so they pulled some parts in. Back with Nehalem, the 45nm dual core mainstream parts were seriously delayed, so they canned that and pulled in 32nm which was close enough.

Who knows when Skylake "desktop" will actually be released. It might only be Skylake for <5W TDP tablet/netbooks that will be 2H2015, desktop CPUs not until 2016?

Skylake Desktop parts are few months earlier than the super low power parts. It's in the leaked roadmaps. I am guessing Desktop in July/August and low power parts in October-December.

So it's confirmed, FIVR will be abandoned. I wonder what the reason is?

Supposedly certain variants of the <5W Y parts are going to retain some form of that.

Don't forget that Intel will also launch a GT4e SKU.

Yea ok, but they are like mid-2016. AMD and Nvidia will significantly improve then. IMO, "impressive" is all relative. If Nvidia is doing 2x and Intel does 1.4x, then Intel is not impressive.

You're just trying to create drama. Skylake was always meant to be a 2H2015 release. 2H could mean anywhere between July or December. Intel reserved some buffer for flexibility rather than nailing down the launch to a specific quarter.

There is no delay for Skylake, but Broadwell will surely have one of the shortest lifespan of recent CPU launches.

It probably won't be too far off from this roadmap: http://www.kitguru.net/wp-content/uploads/2014/07/intel_broadwell_skylake1.png

There is no delay for Skylake, but Broadwell will surely have one of the shortest lifespan of recent CPU launches.

Considering that whatever Broadwell is available won't be in a Skylake version until a year later, I doubt it.

Intel hasn't announcing anything about Skylake, so nothing is confirmed. Still a rumor, I don't know how credible it is since Broadwell already got a 2nd gen FIVR.

 

[Sweepr]

New desktop platform coming.

Intel's Kirk Skaugen told the crowd that Skylake will bring "significant" increases in performance, battery life, and power efficiency over Broadwell. Unlike Broadwell, Skylake products will be broadly targeted across Intel's traditional PC markets, including high-performance desktops.

 

[witeken]

Poll: Hyped for Skylake?

• Yes, Skylake will be a huge improvement
• No, it will disappoint, <12% IPC
• Mainly excited for graphics (Gen9-GT4e)
• Skylake mobile: iPad Pro with Intel Inside
• HYPE

Yep. And most likely a July release.

The evidence is virtually incontrovertible, though.
