I've searched the forums and there doesn't seem to be one? It would be good to have a separate thread for the upcoming processor series.

Personally, I am waiting for more information (leaks) of 6C/12T Coffee Lake-S and I'm secretly hoping for (but not expecting one until Ice Lake) an 8C/16T part for the mainstream platform, and see how both fare against the upcoming HEDT platform.

I need to get caught up: I keep hearing about an Intel 8-core for mainstream/client platform. Someone's musing, rumor, or evidence of such hardware?

Unless you need/want the platform features of X299,
Z370 + 6c/12t (maybe 8c/16t if we're lucky) is definitely the way to go for a gaming rig.

That is unless Intel somehow manages to screw the pooch on either Coffeelake or Z370 itself.

Unfortunately no such part has leaked/seems to exist in the near future (= Coffee Lake). You may have read my wishes for one/several to be released for CFL in another thread? It would be the smart thing to do, however the consensus is that if come will be introduced it will be for Ice Lake (2018).

Even then, Z370 (August) and Z390 (Q1: 2018) will have most of those and other features except those privileged for X299 (number of PCIe lanes, quad channel etc.).

*This is beginning to re-dawn on me too, well, more of a suspicion than anything else really.

Is it known what differences there will be between Z370 and Z390?

Wi-Fi and USB 3.1 according to digitimes.
Intel's upcoming Z370 chipsets, for its Coffee Lake-based processors which are schedule to start rolling out in August, will not feature integrated Wi-Fi and USB 3.1.

Intel originally planned to release the Coffee Lake platform in 2018 with the 300-series chipsets to feature Wi-Fi (802.11ac R2 and Bluetooth 5.0) and USB 3.1 Gen2 , but the CPU giant has brought forward the launch for some Coffee Lake-based processors along with the Z370 chipsets because of competition from AMD's Ryzen processors, the sources noted.

However, Intel was not able to put the intended features into the Z370 chipsets because of the rush, and this is expected to give third-party chip suppliers some time to find new businesses.

However, other 300-series chipsets including the Z390 and H370, planned for early 2018, will support Wi-Fi and USB 3.1 Gen2.

Will coffee lake 4C/4T still be sold as i5 or will it become i3?
I wouldn't mind an i3 with 4 real cores for $120. Better value than the $170 R5 1400 even though that is 8T.

Intel originally was going to do 2,4 and 8 core dies for Cannonlake. But of course the 4 and 8 core die got cancelled. Presumably Intel will stick with that lineup with Icelake.

Time to update the naming. Too many lakes.

Anyhow, I couldn't wait and ordered Kaby Lake i7-7700K. However, I wonder at what clock speeds Coffee Lake 6-Core mainstream desktop CPUs will launch.

3.8 GHz 6-core i7 with HT and 3.5 GHz 6-core i5 without HT?

This is a much needed thread, thank you TheF34RChannel :)

I forsee:
Core i7: 6 cores + Hyper-threading
i5: 6C, and 4C HT
i3: 4C
Pentium: 2C HT, no AVX, Kaby Lake or really bad Cannon Lake?
Celeron: 2C, similar to Pentium

If the 6-core models are simply taking 4-core 65-W models, adding the cores, keeping the same all-core Turbo frequency, rating the new models 95 W, great.

I'm not convinced they'd just move all the 4-core 65 Watt chips to 6-core 91 Watt. But even if they did, what happens with the 91 Watt models? They can't all go to 112 Watts. They may have to drop the clock speed. That's why I was thinking 3.8 GHz i7 6-core HT and 3.5 GHz i5 6-core.

6-core K models take a frequency reduction over their 4-core predecessors, because they are already rated 95 W. No biggie unless you plan on running the K models stock.

I'm skeptical about 8C for mainstream Z370. Intel wants people who need 8C to move to X299. Coffee lake 6C max should be enough for now. It will have superior single thread performance to Ryzen and be quite competitive in multi thread as well due to higher frequencies. Very good gaming CPU.

  • you need a cheap system, or primarily a gaming system - get Z370 + 4/6 core coffee lake
  • you need a more all-around system also good at gaming but can afford the price - get X299 + 7820X or 7900X

I run stock, always. I gave up on overclocking almost two decades ago.

What I'm wondering is how much clock speed they'll give up. Do you think they'll be able to hit 4 GHz stock (non-Turbo) on a mainstream 6-core i7 part?

What I mean by mainstream is non-X series.

Base no. FCT yes.

Intel Core i7-7700: 4 cores, 4.0 GHz all-core Turbo, 65 W, can be turned to 8700: 6 cores, 4.0 GHz all-core Turbo, 95 W.

Non-Turbo frequency doesn't really have purpose in desktop form factors.

Why do you say that?

One thing I'd use 6-cores for occasionally would be video encoding. And that could take a long time, at full tilt. It'd probably throttle at all-core Turbo in short order, unless it was a custom build with some upgraded cooling or something.
