Eh, there are plenty of different models for software engineering compute resources. For any serious work though using shared server resources reign supreme as then you don't have to provide an 8+ core workstation for every engineer which is going to sit idle how much of the time? Instead you just give your engineers 'light' client machines, typically laptops, which provide the additional advantage of enabling them to work outside the office with basically the same capabilities.

Of course, I still prefer to have an actual workstation-class (aka quad core) laptop because the dual core alternatives don't handle all the non-work stuff anywhere near so well

The cost of proper desktop PCs for the developers is nothing compared to the increased productivity you gain.

Also, often you need to check the build output and have the SW build output locally anyway, e.g. when debugging in MS Visual Studio, Trace32 / Lauterbach, gdb, or whatever you use.

And having build run on greater than 8 core servers rather than desktop workstation equivalents represents a further gain in productivity. I'm not disagreeing with that in the least, just saying that a local workstation isn't the absolute best option out there.

3x battery life, 2.5x performance, 30x graphics performance. Really? No wonder they need the disclaimer footnotes.


"Amazing experiences", "Stunning visual performance", "Ready for Business". The marketeers sure have gone overboard with meaningless buzzwords...

Also, "Intel's best processors ever". Well, what else should we expect? If they weren't any better than the old ones, why bother releasing them?

Sorry, I couldn't help myself. But this was simply too much marketing BS for me!

Sure, if you have really heavy builds, it might be worth assigning them to a build server even when developing (i.e. not just for continuous integration and similar). But often I find it's not worth the extra hassle of using a build server for that, having to pull the build output to your PC from the build server when you need to test and debug it etc. In addition developers often do incremental re-builds (i.e. do not compile everything from scratch each time), which usually do not take that long if you have a good workstation PC.

Fair enough, all depends on the environment at that point. When all of that 'hassle' is completely automated then it's all upside - faster turnaround time than possible even for a high-end desktop workstation, lower operating costs per user that improves with the number of users, and you just need to be on the network to access that power rather than remote connect directly to your desktop workstation.

Of course for small/medium software companies such a deployment likely doesn't make sense as there's a cost associated with setting up that type of environment. It's far simpler to just give them a desktop workstation as you say. Or take the next step up and give them a laptop which they can use to remote desktop into a properly managed workstation/server.

So Core m7 6Y75 is 40% faster than Core M-5Y71 @ 3DMark Sky Diver Overall.
This test is 5+ minutes long and Broadwell-Y can only run it at ~600-700MHz. If true this suggests Skylake-Y can sustain higher clocks.

AnandTech said:
3DMark Sky Diver and Cloud Gate: 3DMark is a staple of our reviews. Both run through several graphics and physics tests which work both the CPU and GPU. Sky Diver is the more difficult of the tests. Sky Diver is about five minutes, and Cloud Gate is about three minutes.

Looks like skylake Pentiums will be 2C/2T afterall. But the good news is the TDP will not be 65w and instead be 47w.

When will these chips start being buyable/available? I'm guessing end of the month?

Good news in that case! But where did you find the 6Y75 benchmarks to compare with the Broadwell benchmarks above?

We have Intel's word that it performs 40% better than the fastest Broadwell-Y in a 5-minute long benchmark. Oh, if you don't trust them, then the huge amount of Carrizo marketing slides and reference platform results don't count either I guess. Don't worry, I will be the first to post independent reviews from NBC and others.

Do we have Zen benchmarks? You seem convinced that it will smack any Intel quad-core and I don't see any of them.

There is no way it could score anywhere close to 40% better without higher sustained clocks.

Yea, maybe they pilfered AMD's marketeers.

If Skylake went through 2 "revolutions" you can only imagine what changes have been made to Cannonlake, let alone anything past Cannonlake.

Full lineup unveiled:

Desktop - Skylake-S











http://newsroom.intel.com/community...eration-intel-core-intels-best-processor-ever

Surprise, Intel will integrate the GT2 iGPU in the Pentium lineup!
$75 buys you integrated graphics performance that will be close to Core i7 6700K. 24 EUs (Gen 9) vs 10 EUs (Gen 7.5) inside current Haswell-based Pentium.
Core i3 is 47W TDP, earlier rumours about 65W TDP were false.

Mobile - Skylake-Y



Mobile - Skylake-U







Four GT3e models at 15W TDP. All 28W TDP models will feature the GT3e iGPU. The next Macbook Air and Macbook Pro 13'' will feature Iris models with eDRAM.
Unlike desktops Skylake-U Pentium still packs a GT1 iGPU but now there's HT support (2C/4T just like Core i3).

They are comparing a 5 year old 1st Gen i5 ultramobile vs a current ultra mobile. Yes with 5 generations of improvements and 2 die shrinks you can get 3x battery life, 2.5x performance, and night and day performance from that crappy intel integrated graphics from 2010.

6th Gen Intel Core i5-6200U (43WHr battery size) to a 5 year old PC based on Intel Core i5-520UM (62WHr battery size): 2.5x better performance (SYSmark*2014), 3x better battery life (Windows* 10 on i5-6200U and Windows 7 on i5-520UM)

520um was 1.06 that could turbo to 1.86. It was also first gen turbo and thus was not really good compared to the newer turbo.

Mobile - Skylake-H







As expected 4C/4T Core i5 is now part of the mobile lineup. The lower price ($250) compared to 4C/8T Core i7s probably means cheaper workstation notebooks that perform better than previous dual-core offerings.
25W quad-cores and GT4e models are still missing from today's announcement, I guess we won't see them till early 2016. Edit: Iris Pro (GT4e) in 2016 according to this slide.

Core i7 6820K is an overclockable mobile chip.

Pentiums have same HD Graphics 530 as Core i3's?? Interesting.....

Of course this means "mini ITX system", and it's the first thing that popped into my mind :biggrin: :biggrin:

All that's left now is for someone to fork over/leak the release date and the MSRP of these various chips. I checked over on WCCFtech but they didn't have anything. I'm sure the release dates and prices will be leaked at some point very soon.

I think the MSRPs for most of these are listed in the rightmost column, under "1ku pricing". "Box" is probably the price we'd pay; "Tray" is the price large OEMs pay.

AnandTech: The Intel Skylake Mobile and Desktop Launch, with Architecture Analysis

Intel’s 6th Generation of its Core product line, Skylake, is officially launching today. We previously saw the performance of the two high end Skylake-K 91W processors, but that was limited in detail as well as product. So it is today that Intel lifts the lid on the other parts from 4.5 W in mobile through Core M, to 15W/28W in Skylake-K, 45W in Skylake-H and then the 35W/65W mêlée of socketed Skylake-S parts. For today's formal launch we will be taking a look at the underlying Skylake architecture, which was unveiled by Intel at their recent Intel Developer Forum this August.

As noted in the previous pages, the eDRAM from Intel will come in two flavors – 64 MB and 128 MB, which is different to the 128 MB only policy for Haswell and Broadwell. Back when Intel was discussing eDRAM before this, it was noted that Intel considered 32 MB ‘enough’, but doubled it and doubled it again just to make sure the system truly saw some benefit. It seems that for some circumstances (or some price points for that matter) 64 MB is felt as a better fit in that regard, given that Intel believes that its initial design had plenty of headroom. As far as we can tell, eDRAM will be available in 64MB for GT3e and 128MB for GT4e configurations (48 EUs and 72 EUs respectively), although we might see some variation as time goes on. We have confirmed with Intel that the 64 MB implementation is a half-silicon implementation (rather than a disabled full-silicon), but the bandwidth to the system agent is the same in both circumstances.

It is worth noting that the Skylake-Y package is crazy small. At IDF Intel showed off a finished Skylake-Y package to demonstrate the CPU die size in relation to the package size, and to compare the overall package size to the already small Broadwell-Y package. While both packages are still 16.5mm wide, Intel has compacted the overall layout and squared off the CPU die, bringing the height of the Skylake-Y package down from 30mm to 20mm, a 33% savings in package size.

AnandTech says 2C+GT2 Skylake-Y's die is 98.5mm².

http://www.anandtech.com/show/9582/intel-skylake-mobile-desktop-launch-architecture-analysis

Intel mentioned Skylake-Y provides 2x the performance of iPad Air 2 @ Tabletmark and WebXPRT 2015.
To put things in perspective:

wait wait wait, hang on a minute there... that has to be wrong, its either 2/4 + HD530 (GT1.5 acording to driver), or 2/2 (GT1, 510)... dont tell me they intentionaly decided to put in the 2/4 w/GT1.5 intro desktop and them disable the HT.... come on...

Also is strange for the 4405U to have HD510, its the only mobile SKU with GT1?! strange.

Anyway, this is from a July driver...
Mobile U
iSKLULTGT1 = "Intel(R) HD Graphics 510"
iSKLULTGT15 = "Intel(R) HD Graphics 510"
iSKLULTGT2 = "Intel(R) HD Graphics 520"
iSKLULTGT3 = "Intel(R) HD Graphics 535"
iSKLULTGT3e = "Intel(R) Iris(TM) Graphics 540"
iSKLULTGT328W = "Intel(R) Iris(TM) Graphics 550"

Mobile Y
iSKLULXGT1 = "Intel(R) HD Graphics"
iSKLULXGT2 = "Intel(R) HD Graphics 515"

Mobile H
iSKLHaloGT4 = "Intel(R) Iris(TM) Pro Graphics 580"
iSKLHaloGT3fe = "Intel(R) Iris(TM) Graphics"
iSKLHaloGT2 = "Intel(R) HD Graphics 530"

Xeon
iSKLSRVGT4 = "Intel(R) Iris(TM) Pro Graphics P580"
iSKLWSGT2 = "Intel(R) HD Graphics P530"
iSKLWSGT4 = "Intel(R) Iris(TM) Pro Graphics P580"

Desktop
iSKLDTGT15 = "Intel(R) HD Graphics 530"
iSKLDTGT1 = "Intel(R) HD Graphics 510"
iSKLDTGT2 = "Intel(R) HD Graphics 530"
iSKLDTGT4 = "Intel(R) Iris(TM) Pro Graphics 570/580"

Notice how HD530 is used for both GT2 and GT1.5 on desktop and HD510 is used for both GT1 and GT1.5 on U... man what a mess.
