Nice fine.

Hopefully the roadmap means mobile Cannonlake is out at the time when the 300 series chipset releases.

300 series is Cannon Lake PCH, except Kaby Lake-R Z370, correct? Then why is Z390 coming that much later?

The Kabylake Z370 chip wasn't planned. It was likely a rushed launch.

Since Coffeelake needs a new chipset, but the Cannonlake chipsets weren't suitable they created Z370. Now they need a replacement, which is Z390. They aren't going to launch the replacement a month later, you have to make money.

Looking at the above roadmap, im quessing only the K models of Coffeelake will relese in Q4 2017 ??

That's been the rumor for awhile. Considering that Intel is going to be cutting into their margins quite a bit with this release I think they wanted to make sure the pent up demand went to higher ASP products first. Kind of like AMD releasing the 7 series Ryzen's first instead of releasing the R5 at the same time.

So the current Z270/B250/B350 won't work with Coffeelake CPUs?

That would be a poor marketing choice on Intel's behalf. AMD would eat Intel's lunch - so I think not.
Well if you want a CoffeeLake in Q4 2017 you will only be able to buy a more expensive Z370 motherboard . I dont believe a lot of users with a locked Coffeelake would like to spend more for the Z370 bords. So i believe only two models will release in Q4, 8600K and 8700K. Rest of the SKUs in Q1 2018 along with the rest of the smaller chipsets.

There aren't just 2 products to launch; there are 6 that have prices: Core i3-8100, 8350K, i5-8400, 8600K, i7-8700, 8700K.

Nice find @nvgpu. LGA 1151 v2's Z390 in H2-2018 and Ice Lake rumored to arrive next year, maybe Q4 is in the cards depending on 10nm+ progress. Some updates on leaked CFL-S & SKL-X scores...

- Core i9-7940X @ Geekbench 4
- Core i5-8400 @ SiSoftware (Processor Multi-Media)
- Core i7-7700K @ SiSoftware (Processor Multi-Media, Stock)
Thanks, finally something on 7940x too. Not that its needed that much, as its performance can be easily inferred from the leaked results of the 20x, 60x and 80xe, but still....

for whatever reason the CPU, which interest me the most out of the stack, is the one ignored by the media :-D It was the same last year with 6850k - everyone and his mother would review 6950x, 6900k and 6800k...6850k not so much.

Well forgot the 8350K, but even if they will release the other locked CPUs i dont believe they will sell alot of them with just the Z370 available in Q4 2017.

What you are saying is likely correct. But the impression that they have a new product will still be a positive thing for them.

It is a very messy launch. Their problems with 14nm and subsequent cancellation of Cannonlake has brought something very undesirable for them. It also happens to be the same time when Ryzen is ramping up.

Considering how messy the launch is I wonder if Coffelake should have just waited until CNL-PCH chipsets are released. Maybe its the management playing the epeen game with competitors(AMD for example).

Does that roadmap suggest that IceLake will actually might be compatible with Z390 chipset?

Possible, but since Ice Lake & Tiger Lake is a new microarchitecture, don't expect them to use socket LGA 1151, they'll use a new socket.

The Z390 designation is new info - thank you - and is what Intel has been calling the "Coffee Lake S & CNL PCH-H (300 Series) Platform," correct? See this slide that was posted last month on many sites, the right column is what's now known as Z390:

How many pci lanes is the 370? Same as 270 i take it?
I don't think anyone knows. I've seen different answers. Some say 16 lanes, others say 24. Some say its 24 including chipset, so really just 16 while others say its a true 24 from the CPU. So, no one knows. If they do know, let them come forth and clear the confusion.

According to this its 24 PCIe Gen 3.0, the problem is the DMI 3.0 (4x PCIe- Gen 3.0) connecting the CPU with the Chipset.

Their original plan did seem to include non-K CPUs: if you remember a while ago we got hold of a slide from an Intel partner presentation showing their intent to launch CFL in Aug-Sep. That slide included "6 and 4-core / 95W K, 65W" SKUs in the first batch, with the second batch scheduled for Q1 2018 consisting of "6, 4 and 2-core / 95W K, 65W, 35W" SKUs.

Now, obviously things changed ever since that slide was leaked, CFL got a later launch date, but whether non-K SKUs will be absent from the first CFL batch does not solely rely on cheap chipset availability, at least as far as Intel is concerned.

I still don't know how will they reach 95W TDP at 4,3GHz with 6 core. I know "TDP" is not for power consumption, but lately everybody is basically using it as power consumption.
Maybe with base clock 3,7GHz, but even that could be hard to reach.
