I guess with mobile the main difference is the cooling of the cpu? Better cooling giving more turbo time?

I wonder what variation you'd get if you compared a bunch of desktop systems from different mfgs with the same CPU?

They can't be considered identical, can they? There are probably differences in RAM speed and capacity, and storage differences. And then you have to factor in thermals. What about different customers drivers installed and BIOS versions?

At times, even different GPUs have different 2D performance. Which is why it's best to keep everything same as possible, which won't happen in laptops.

Some notes in digging through the public patches so far:

- Indeed, Cannonlake is "Gen 10" graphics.

- Cannonlake PCI IDs for -U models are 0x5A52, 0x5A5A, 0x5A42, and 0x5A4A.

- Cannonlake PCI IDs for -Y models are 0x5A51, 0x5A58, 0x5A41, 0x5A49, 0x5A71, and 0x5A79.

- Many similarities to Broxton (no surprise).

- There appears to be a number of differences with regards to power management and its low-power mode.

Cannonlake is coming.

Guessing it supports Intel SHA extensions which Goldmont supports but Skylake & Kaby Lake didn't.

Just like to see what performance variation you get with desktop systems. Get a Dell, an Acer, an HP, etc. Get the same CPU, same rated ram, and the same video card. Make sure they all have the latest BIOS and drivers. Run some benches and see if anything interesting comes up.

But who is the "high performance client" company they're targeting? I only know Nvidia, but Intel and Nvidia compete in the data center / HPC and AI.

So is CNL-U/Y going to replace KBL-U/Y while CFL-H will replace KBL-H, or...? Looks like two separate lines, one for 4.5-15W TDP optimized for low power and the other for 45W TDP optimized for raw performance,

https://benchlife.info/intel-x299-platform-might-launch-at-computex-04092017/

Benchlife reports that Intel is moving up its Skylake-X scheduling a couple of weeks. They are assuming it might launch at Computex. To be exact Skylake-X production window moved up from week 31-35 to week 25-27. Also they are saying that Coffee Lake is expected to debut in the fourth quarter of 2017. If this is true Intel also moved up its Coffe Lake scheduling.

Great news. If true this means we are barely 2 months away from the new HEDT beast. We can also expect mainstream 6C/12T from Intel sooner. Peolple were talking Q2-2018 for Coffee Lake-S before this leak. The lack of news regarding a new socket for CFL-S implies it's LGA 1151 in my eyes. It would be a great upgrade path for Skylake/Kaby Lake users if compatible with 200 Series motherboards. Much better MT performance while not giving up per core performance for CPU intensive games and other tasks.

Impossibru, I was told these things are on a precise schedule and cannot be accelerated at will.

Looks like the original DigiTimes article got it right then:

According to Intel's roadmap, the chipmaker is expected to roll out its 10nm notebook-use Cannon Lake and 14nm desktop-use Coffee Lake CPUs in the second half of 2017 and to bring out Ice Lake CPUs in 2018.

If they got the second part right as well, we can expect Intel's next-generation Ice Lake as soon as next year. :)

Has intel ever officially confirmed 6/12 for Coffeelake S? If they make it compatible with Z270, it would really help their line up. One could get the best current gaming and single thread performance (7700K) with an option to move up to six cores as games become more threaded. I still dont understand how the model line up will fall out though, between hex mainstream and Hedt hex core. It would really suck if they gimped the mainstream hex core by making it not overcockable or something like that. What they should do is make the Hedt line up 8 cores plus, and cut the price of the entry level 8 core to the 500.00 range.

Intel hasn't even officially confirmed that they are doing Coffee Lake. Only the Kaby Lake Refresh and Cannonlake.

From the slide it is clear how Intel is able to accelerate it. QS scheduling didn't change, but the gap from QS to production is much smaller. Looks like Intel is confident that the QS models are ready to go into production shortly afterwards.

This is incorrect. Intel was talking about Coffe Lake some time before the first Leak appeared. However the core config wasn't known, at least not for public.

There is a new Sisoftware listing from Cannonlake.

Genuine Intel(R) U 0000 @ 3.30GHz (2C 4T 3.31GHz, 2x 256kB L2, 4MB L3)
http://ranker.sisoftware.net/show_r...d4ecdce5dde9dafc8eb383a5c0a598a88efdc0f8&l=en

There is a difference to the first: Z0 and U0.

Intel Cannonlake Client platform CNL - Z0 Cannonlake Client System
Intel Cannonlake Client platform CNL - U0 Cannonlake Client System

The strange thing is that it reports Gen9 because as we know CNL is using Gen10. Also it reports that it is using a graphics unit with 48 EUs. The recent CNL ID listing says it is GT2 only.

Intel(R) HD Graphics Gen9 (384SP 48C 1GHz, 6.3GB) (OpenCL)

I don't quite understand. It takes 3 months to produce a CPU, so what does production mean here.
