Intel Skylake / Kaby Lake

[Sweepr]

As I said before, HEDT offers more lanes and more cores. This matters if you run multi-threaded applications or are a SLI/CrossFire user. Otherwise, it's pretty much a draw. Most will take the ~7%+ improvement and lower power usage of the newest generation.

I agree. You pay a premium for this, extra cores and PCIe lanes.
As long as mobile gets the new cores sooner than servers, 'E' series will be behind.
With that said, I'm not 100% convinced we will see Broadwell-E, it could very well be cancelled by now with Skylake-E coming late 2016 or early 2017.

Thanks FanlessTech!

www.fanlesstech.com/2015/07/exclusive-skylake-boost.html

10 to 20 percent better performance-per-watt for single-threaded CPU tasks
Up to 50 percent better Intel HD graphics
Support for hardware-accelerated HEVC encoding
Integrated support for 4K cameras or up to 4 HD cameras
Up to 30 percent longer battery life (If a device got up to 8.5 hours of run time with a Broadwell chip, the same hardware should last for over 11 hours with a Skylake chip).

Intel says the new chips will feature enhanced audio processing technology, improved touch sensor technology, support for Cat6 LTE, WiDi 6.0, Bluetooth 4.1, eMMC 5.0, SDXC 3.0, and more.

System configurations in speaker notes and appendix

The last slide isn't really meaningful without infos about "vs previous generations" reference devices.


Does anyone know what is VDENC and SFC?

 

[ShintaiDK]

Nice find Sweepr!

What an upgrade to the Core M series:
- Up to 17% CPU performance faster @ SPECint
- Up to 41% faster @ 3DMark 11 Performance Preset Graphics
Likely the result of architectural improvements + higher sustained clocks (something that hurt the 1st generation)
- 30% longer battery life @ same battery capacity (HD video playback)
- Storage & I/O improvements, eMMC 5.0 / PCIe 3.0 support
- HEVC Decode/Encode

Assuming they compared SKL-U/Y GT2 against Broadwell there is a nice GPU gain, especially with 3dmark11 which wasn't a best case in recent leaks.

 

[Sweepr]

Skylake-U:
- Up to 10% CPU performance faster @ SPECint
- Up to 34% faster @ 3DMark 11 Performance Preset Graphics

Now most people are not replacing Broadwell-U but Haswell-U and older notebooks. According to NotebookCheck Broadwell-U is 5-15% faster (CPU) and 20-25% faster (graphics) than Haswell-U.

Rough calculation, someone upgrading from one of the many Core i5 4200U notebooks might expect ~15-25% better CPU performance and ~60-65% better graphics performance from a similar Skylake-U notebook (equipped with dual-channel RAM).

They're probably comparing the GT2 SKUs in the third slide. GT3e deserves Iris or Iris Pro naming instead of HD Graphics. This means GT3e SKU might be faster than that (>34% faster than Broadwell-U @ 3DMark 11).

Assuming they compared SKL-U/Y GT2 against Broadwell there is a nice GPU gain, especially with 3dmark11 which wasn't a best case in recent leaks.

Indeed, and I think that's what they did.

This important for Skylake Y. But from what data did you derive that higher clocks can be sustained without throttle?

 

[dark zero]

The only one who gets real evolution is the Skylake H. Quad Core i5 >>>>>>>>>>>> the rest of upgrades.

 

[Sweepr]

Considering Broadwell-U scores ~1250 points using dual-channel RAM (AMD itself actually puts it closer to ~1300 but let's settle with less, I'm using NBC numbers), 34% faster than that would put Skylake-U at ~1675 points. That's actually remarkably close to what looks like the most popular 15W Carrizo SKU (A10 8700P, 1764 points) (also faster than the low-end A8 8600P, 1582 points) and let's not forget we're talking about the bread and butter GT2 'HD Graphics', not the GT3e Iris Pro SKU. CPU-wise it's no contest, I think Carrizo will have a hard time matching Core i5 Skylake-U in MT benchmarks and will get absolutely destroyed in single-thread tasks.

Intel really did step up their game with Skylake (especially mobile).

These are also made under extreme cooling, likely LN..

The voltage delta between 4.2 and 4.4 is even better than the theoricaly perfect one, they forgot to set the voltage at 4.4 such that this blatant contradiction wouldnt appear but i guess that the numbers had to look good...

Weren't you just saying you want Intel fans out of AMD threads? You go first and stop being a troll in Intel threads.

I'm betting you can't stop yourself.

 

[Fjodor2001]

"S-Series (desktop): Up to 11% faster CPU performance, 22% lower TDP (65 W vs 84 W)"

Surely this is "pick one of two" right? I doubt the 65 W 6700 @ 3.4 GHz is 11% faster than the 84 W 4790 @ 3.6 Ghz?

And shouldn't they be comparing against 88W 4790K for max performance?

 

[mikk]

Surely this is "pick one of two" right? I doubt the 65 W 6700 @ 3.4 GHz is 11% faster than the 84 W 4790 @ 3.6 Ghz?

Why not? Both can go up to 4 Ghz in best case, there is no clock deficit like 6700k has against 4790k. I don't think 65W is a noteworthy limitation for CPU only benchmarks (unless they are using Prime95 with AVX2 or similar).

So...if one gets excited about mobile chips Skylake is awesome....

If one gets excited building their own desktop beasts, Skylake is 11% more awesome. (In marketing terms)

And the much improved battery life on the desktop will be greatly appreciated. You know how many penlight batteries it takes to keep my 750G2 fed? Yes, you do, because you're so awesome! Looking forward to finally being able to charge my desktop wirelessly. Won't have to drag my Tesla coil all around the house. Thanks, Intel!

And I can throw away my dGPUs because Intel graphics marketing slides are even more awesome!

And more awesomeness, can expect a much improved touch experience with my mouse!

And audio - I can throw away thousands of $$ in external Pro DACs/amps/DAWs/VSTs/NLEs, because Skylake is so much better!

And I will talk better with your improved speech capabilities! Yay! Stupid Neumann and Schoeps have no place in the 14nm DSP world.

Most importantly, thank you, Intel, for enthusiastic support for enthusiasts!

You realize you're years too late to crash the iProfit party - screw Apple - now you can focus your chip chops on the remaining loyal desktop enthusiast customers. All 150,000 of us! You're just so awesome!

PS - Will we be able to overclock the wireless charging to match our 6Ghz overclocked Skylake desktops, with count 'em F O U R Cores?

PPS - Will your supply channel for Skylake-S (S stands for SuperDuper-Sky-is-the-limit Super Overclocking) match the great efficiency you achieved with your ample Broadwell-C global product supply?

PPPS - All those wimpy chips for mobile devices was a typo, right? Just leftover copy from 2010 -`You love enthusiasts more than the throngs of throw-away gadgeteers, yes?

Dang Clockhound.. tell us how you really feel! :biggrin:

I'm in the same boat as you, waiting another year for Skylake E :whiste:

they could stay status quo on the performance side for my sake, just make it NOT throttle! I'd get a 14" surface pro with that.

 

[Fjodor2001]

Yes, but I was talking about sustained performance, not turbo.

Also, interesting that they skipped comparisons of their top Skylake SKUs, the 95 W TDP ones. Should have been compaired to 88W 4790K. But I guess the PP slides would not look so nice then, with increase in TDP and only minor perf increase.

Clearly, Skylake seems to have improved most in the low power SKUs.

 

[tential]

Thanks sweepr for that post. I'm so excited that I waited to get a laptop. Haha noooo I'm going to be broke at this rate

 

[mikk]

I'm talking about sustained as well. On a desktop model this includes Turbo.

Great slides. I'm pumped!

What exactly would you like from Skylake? If you say a mainstream hex core, I would agree. Otherwise, if one accepts these slides it seems like a solid improvement, not really sure what you expect. Face it mobile is the focus and that is not going to change. If the 10% performance increase is in absolute performance, I would be happy with that. If it is just the same performance as before, but at lower power, yea, not too excited about that.

 

[frozentundra123456]

Great slides. I'm pumped!

Wow, battling slides, Carizzo vs Skylake. I want to see some real availability of product from both sides, with independent real world tests.

 

[dark zero]

Waiting for hex core Ms desktop. My bro will be happy with the REAL quad for Notebook

Decent improvements in the low tier I see. Interesting... But I am wondering if the i7U will beat the quad i5H considering that the i5M Haswell was toe by toe against the i7U Hw.

And since there are 35W quads at 2+ Ghz... When we will see the 15w quads at at least 1.6 Ghz?

 

[Arachnotronic]

Wow, battling slides, Carizzo vs Skylake. I want to see some real availability of product from both sides, with independent real world tests.

I'm sure you will see plenty of designs using Skylake in the market soon enough

Crossing my fingers for a Retina MacBook Air...

 

[IntelUser2000]

I would be happy with that. If it is just the same performance as before, but at lower power, yea, not too excited about that.

This is exactly what's been happening for the past few years. We went from a 35W chip to a 15W one that essentially performs the same, since Core i5/i7 chips in 2011!

People really think they'd be upgrading Core i5 4200U devices that cost them a grand+ for 20% extra performance? Really? If it offers a jump similar from Core 2 Duo to a Core i7 6700K to consider replacing my Core i7 3517U XPS 12, while expecting the device to be significantly lighter, thinner, and better battery life. Looking at how slow progress is and every year its getting slower, that's not going to happen until 2025 at the earliest.
