Intel Skylake / Kaby Lake

[Arachnotronic]

I read that too but thought it was a typo. Will the BGA Xeon E3 or the ''H'' mobile version pack 128MB eDRAM then?
Current Haswell Iris Pro chips pack 128MB, don't they?

"H" chips will be 128MB; the socketed variant (if Intel releases it), will be 64MB. See mikk's post here:

Thanks, for some reason I missed it. So Broadwel-K Core i7 5775C will be the first from a new line of LGA chips with top notch iGPUs from Intel. I wasn't expecting to see 4+4e parts at only 35W TDP either, impressive.

I feel like we are being enticed too much by uArch enhancements.

Nehalem was a let down, compared to how long Core 2 Quad (6MB and 12MB L2 models) was viable. (and to some extent still works hella good for everyday usage)

Sandy Bridge was just awesome for the price, no two ways about it.

I currently have 16GB of DDR3 RAM and that makes everything better (anecdotal anyway).

I would want 32GB of RAM for a true upgrade, and I don't see that getting sold for $100-$150.

So why spend again for something I already paid for?

I think the one after Skylake, after DDR4 has flooded the market, will be more worth the money.

Let me reveal something truly revolutionary.

You could purchase 16GB of DDR4 memory when Skylake launches. You could then purchase an additional 16GB of DDR4 memory at a later date, perhaps when there is no premium for DDR4.

You would then have the 32GB you desired.

If you upgrade slowly like me sometimes, by the time you want more DDR4, DDR5 will already be less expensive.

Not really. 4+4e is probably going to end up like Broadwell- C/R chips where the CPU part clocks low and Cannonlake comes with high clocked CPU + GT2 graphics. Also 35W means that performance will be lot less than the 35W.

Unless Skylake has something fantastic for the graphics(indications are it isn't), 35W 4+4e is going to be not much faster than Broadwell GT3e.

 

[biostud]

Yup. The broadwell core is out. HEDT is not using it. HEDT is a generation behind. Easy.

Why is there this logic, that if you can't buy it, it doesn't exist? Broadwell IS OUT and exists. It's irrelevant if Intel decided to release it in purchasable desktop skus that YOU want. Core-M is out as well as many other Broadwell skus. The core exists, it's out, HEDT is not using. HEDT is a generation behind.

I don't know how many more ways to explain it

That is true, but mainstream desktop is a generation behind too, using that logic, so HEDT is the same generation as mainstream desktop.

Do we have any kind of realistic estimation of when will Skylake-H chips be available?

Sorry If has been comented already, I haven't found anything here in anadtech, and everywhere else it ranges from July to early 2016..

I'm waiting for the Macbook Pro 15" upgrade, and I would like to know how much of a chance is there for a Skylake update instead of the Broadwell one (no signs of Broadwell-H anywhere also...)

I dont think you gonna see any H models in Macbooks. Apple prefers Y and U.

MacBook Pros 15 run i7-4870, 4960 or 4980 HQ CPUs.

Colour me surprised.

My mistake then.

Nobody at the offices here gets anything but Y/U models.

 

[Sweepr]

Not really. 4+4e is probably going to end up like Broadwell- C/R chips where the CPU part clocks low

Broadwell-K is clocked at over 3GHz, not low at all for a 65W part with GT3e graphics.

and Cannonlake comes with high clocked CPU + GT2 graphics.

Cannonlake might hit desktops in a limited way, just like Broadwell.

Also 35W means that performance will be lot less than the 35W.

You mean 65W? It's kind of obvious twice the TDP gives better performance but the best they got out today are 47W 4C+GT3e parts while that particular Skylake SKU packs 4C+GT4e at 35W. Yup, I'm impressed.

Unless Skylake has something fantastic for the graphics(indications are it isn't), 35W 4+4e is going to be not much faster than Broadwell GT3e.

While I don't have high expectations either you don't know enough about Gen 9 to downplay/praise its graphics performance or compare it to current chips.

 

[ShintaiDK]

35 to 65W is rather limited. Take the i7. +600Mhz base +400Mhz turbo.

Quite a stepup from 22nm. Where you got +900Mhz base and +700Mhz turbo.

 

[Dave2150]

If you upgrade slowly like me sometimes, by the time you want more DDR4, DDR5 will already be less expensive.

DDR3 lasted 7 years before DDR4 was first available. DDR4 will probably last even longer, given the slowly declining desktop PC userbase.

Obviously I meant he get the final 16GB in a shorter timeframe, such as 6 months to a year later

Yes, congratulations for understanding that memory and other electronic devices, have increased in price over the last few years.

 

[NTMBK]

Wait, Skylake still doesn't integrate the southbridge into the SoC? Oh come on, that's just leaving perf/W sitting on the table. If Intel really wants to take tablets, every fraction of a watt (and every mm^2 of package area) matters.

At least they're shrinking it to 22nm this time

But yes, I think for ULT/Y class processors, integrating the PCH is something the company will need to do.

 

[ShintaiDK]

At least they use Omnipath? on the Y/U. While the H/S uses a DMI 3.0 aka PCIe 3.0 x4.

But the use of it might hint a future integrated happens at Icelake.

If I remember correctly, "OPI" stands for "On Package Interface", not Omnipath. But yeah, it should be less power hungry than going off package, at least.

 

[B-Riz]

My earlier commented stated I consider it only a true upgrade if I can double my memory for a little bit more money than what I paid for DDR3.

The whole point of shrinking circuits is lower power usage, higher density, etc.

More for less, it has been the trend since 8088 came out.

32GB *should* be $150-ish sometime in the future.

I know prices went up, the mfgs. have kept production low so the low prices and supply glut was not repeated.

And guess what, they are going to get paid again for DDR4.

 

[Luddite]

What about Skylake E or EP Xeons?

Are they coming out this year?

Broadwell-K is clocked at over 3GHz, not low at all for a 65W part with GT3e graphics.

Sure it is. Compared to 4790K/6700K.

Cannonlake might hit desktops in a limited way, just like Broadwell.

I think Cannonlake will have a staggered launch just like Broadwell and Skylake. Mainstream Desktops get Cannonlake at 65W, 95W for 6700K replacement with GT2, and Skylake GT4e @ 65W with low clocks. Of course, Cannonlake may be a firmly 2017 part and they won't have to do that.

While I don't have high expectations either you don't know enough about Gen 9 to downplay/praise its graphics performance or compare it to current chips.

Sure we do. It's quite obvious Broadwell-K/C(w/e its called) is THE graphics-oriented chip for this year. That means GT2 in Skylake is quite a bit lower performing than that. GT3e is about 60% faster than GT2: http://www.anandtech.com/show/6993/intel-iris-pro-5200-graphics-review-core-i74950hq-tested/6

Since Broadwell unlocked is going to feature much lower performing CPU, the iGPU performance advantage over Skylake-K has to be the differentiator. Gen 9 is going to end up 20-30% faster than Gen 8, optimistically. It can't be any faster than that, because Gen 9 being 25% faster than Gen 8 means Broadwell GT3e will end up only 30% better than Gen 9 GT2, which for graphics is not much.

Why do you have 3 user accounts? Or are Dave2150, Dave5120, and Dave3000 all different people? Is this in case one gets banned for being too obnoxious on the CPU forums you already have a backup plan? :biggrin:

Is 4790K or 6700K 65 watts or do they have GT3e? That is why the previous poster is saying it does not have low clocks, relative to the TDP and big igpu. If you dont like that, just buy 4790K or wait for SKL. Personally I think the clocks on 14nm are great compared to the FUD the 14 nm naysayers were spreading earlier.
