Intel Skylake / Kaby Lake

[B-Riz]

So realistically, when do you guys think Skylake will hit the market and actually be available for purchase with the appropriate platform (mobo/chipset)?

It should be very close to the Win 10 launch, within a month maybe?

I would almost bet a large sum of money that Intel and MS are working things out to get massive back to school sales that transition into massive holiday sales.

Well, I'll keep my eyes and ears open. Am planning a new build for the June/July timeframe and hopefully as time draws nearer it should become more clear when it should actually be released. I generally don't like waiting for hardware as there's always something new around the corner, but this might be a big step up and worth the wait? I dunno, but we'll see I guess.

Added bonus will be that AMD's R9 3xx might come out around that timeframe, as well as Win10 like you mentioned which should finally be the way Win8 should've been. Hopefully mobo manufactureres will have at least several good mobos out to choose from.

More from the original source of the leaks, first Skylake benchmarks:

www.pcfrm.com/intel-i7-6700k-vs-i7-4790k

~15% faster than Haswell clock per clock. Looks like a solid Tock.
Core i7 6700K almost matches the hexa-core Core i7 5820K, while 4-thread Core i5 6600K almost matches FX9590 (220W TDP) @ Cinebench.

Being a '6700K' I am guessing it's an engineering sample?

Probably.

 

[Arachnotronic]

15% perf/clock improvement over HSW (~9% improvement over BDW implies), better PCH with more features, much improved IGP/media engine.

This looks like a winner. Sign me up for one 6700K whenever it launches.

 

[Sweepr]

Compared to the older chips:

Core i7 6700K is:
30,5% faster than Core i7 4770K.
38,4% faster than Core i7 3770K.
50,85% faster than Core i7 2700K.
86% faster than Core i7 965.

Core i5 6600K is 23.5% faster than the slightly lower clocked Core i5 4570K (3.5 vs 3.4GHz).

Impressive.

What are people using as their benchmarks to determine how much BDW improves in IPC over HSW?

Any links?

In a slide discussing Xeon D, Intel said BDW brought a ~5.5% increase in per/clock over Haswell. I'm just going by that.

NotebookCheck results mostly agree.

 

[Gundark]

This might be a worthy upgrade from Ivy.

That was a long wait. I can finally ditch my 4770K.

 

[alcoholbob]

Are these benchmarks clock speed normalized among Intel cpus? I can't see a stock 3.3ghz 5820k being faster than a 4.4ghz 4790k in those games, in fact it directly contradicts most benchmarks from gaming sites.

The 5820k is only 6% slower when 2 cores are disabled in GTAV for example (and only with HT disabled) so unless 4 cores of 5820k at 3.3ghz = 4 cores of 4790k at 4.4 ghz the results look fishy.

The 5820K is 3.6Ghz if you want to use turbomodes. Plus the 5820K got 15MB of cache and quadchannel memory.

It doesnt contradict benchmarks.

I agree the 5820k results dont contradict benchmarks. In fact the even lower clocked 8 core Haswell E is consistently on top of the game.gpu benchmarks, although I am not sure why.

Back on topic, these results are good, but nothing worthy of some of the hype and expectations being thrown around I am afraid. We just have to remember this is a 2 generation jump, so even if the 15% improvement holds up, it is about what we saw from SB to HW. 5% boost for the tick and 10% boost for the tock.

It might be enough to make it worth considering upgrading from SB though. If you use stock clocks for sure, but if you have the SB at close to 5ghz, still not gaining that much.

I'm more interested in the chipset than the CPU. Previous leaked slides showed the Z100 Skylake would support 20 PCI-E 3.0 lanes from the chipset, up from the Z97's 8 PCI-E 2.0 lanes. These latest slides say the chipset PCI-E lanes are being updated to 3.0 but don't list the number of lanes (PCI-E lanes direct to the CPU remains at 16). These new slides refer to "40% more high speed I/O" but it's not clear to me what this 40% figure refers to.

More from the original source of the leaks, first Skylake benchmarks:

11515/10100 = +14%
Except 4790K runs @ 4.4GHz while 6700K runs @ 4.2GHz.
More close to 20% IPC improvement. Not bad!

Same here.


Looks very promising

Dont get your hopes up. they are all connected with a PCIe 4.0 aka DMI 3.0 interface.

The added PCIe lanes are simply to support M.2 drives.

You meant PCI-E 3.0, right? I thought DMI 3.0 has a transfer rate of 8 GT/s which is the same as PCI-E 3.0. PCI-E 4.0 is 16 GT/s. This is what confuses me about that 40% figure in the slide. DMI 2.0 has a transfer rate of 5 GT/s so a change to DMI 3.0/8 GT/s is a 60% increase, not 40%. I can't figure out where this 40% figure comes from.

So basically, until Skylake-E is released, the Haswell-E/X99 is the only platform that won't get bottlenecked by PCI-E based SSD.

Delivering higher IPC gets harder each time. +15% faster than the impressive Haswell core at almost same clocks as Devil's Canyon is great, that's the first 14nm desktop flagship.

Sorry yes, 3.0. Not sure how it ended up as 4.0.

 

[JoeRambo]

Impressive. Almost 20% IPC gain over Haswell is ridiculously good and totally unexpected. I was hoping for 10% in generic codes and 15% with recompile. I am itching to get my hands on 6700K and see how certain code runs on it

Has there been single thread benchmark numbers published? All I see is MT Cinebench, so it's hard to say what the IPC improvement is for ST.

Hopefully it's the last*...I want Cannonlake in 2016.

*on the mainstream platform.
