Intel Six Core Lineup exposed - Core i7-8700K and Core i5-8600K

Intel Six Core Lineup exposed - Core i7-8700K and Core i5-8600K

We've been talking and debating intel Coffee Lake for some time now. new information surfaced on the web, including SKU names and base clock frequencies. The big daddy proc would be the Core i7 8700K with a 3.7 Ghz base-clock in a 6c/12t configuration.

Actually Intel would be planning to release four six-core models, two of them get hyper-threading, two will not (Core i5 versus i7). Coffee Lake processors will be fabbed at a 14nm node and would be available on LGA1151 within months. French magazine Canard PC is basing the new information up-on reports that the first samples have been supplied to customers. The top model Core i7-8700K would get a 3.7 base clock (turbo's are not yet known).  A non-K model would get a lower 3.2 GHz base clock.

Currently the release lineup looks like this:

Processor Cores / Threads Clock speed Turbo L3 TDP
Core i7-8700K 6/12 3,7GHz tba 12MB 95W
Core i7-8700 6/12 3.2GHz tba 12MB 95W
Core i5-8600K 6/6 3,6GHz tba 9MB 95W
Core i5-8400 6/6 2.8GHz tba 9MB 65W

The Core i5-8600K however would be getting a 3.6 GHz base clock and is an unlocked model. Intel supposedly also will release a Core i5 series with the Core i5-8400 would run at a base of 2.8 Ghz, and is locked. Coffee Lake should be released together with the Z370 / H370 chipsets and logic assumes a release later this year in the Q3 region. Intel 300 series desktop processor motherboard would be based on the current LGA 1151 socket, the SiSoft results already have shown Platform entries.

aren't those dual cores though ? i know some of the i7's are on the mobile market correct me if i am wrong .

Yes, they are. And many of the mobile i7s are dual cores too. But the fact of the matter is, a quad core i5 is basically an i7. So it's no longer the same performance tier.

The i5 has been the budget processor for gaming for some time now, the lower stuff is just the better than nothing option. My point is that it´s ridiculous that atom and i3 owners can extract more efficiency/performance from their cores.

Total extractable performance per core is meaningless. What matters is:
- Performance per thread (For single threaded workloads)
- Performance of entire CPU (For Multi threaded workloads)
Therefore meaningful thing here is performance per $ paid. And there i5 is between i3 and i7.
aren't those dual cores though ? i know some of the i7's are on the mobile market correct me if i am wrong .

Yes, mobile i3/i5/i7 are 2C/4T, their differentiators are clock, cache size and iGPU performance. This applies to basically all CPUs below 25W.

Then intel has those i7-xxxx HQ/MQ/... which are 40W+ and they are real 4C/8T.
Funny part is that they cost around same as those low power 2C/4T (~$400).

But in ~95% of intel's notebooks, you'll find 2C/4T.

HyperThreading isnt that big of a deal in many cases. I have it disabled currently because of the Skylake HT bug, and dont notice much difference.

This is indeed good news and I am hoping once this is released that Intel will make a hex core mobile CPU for Laptops and the Laptop manufactures can make a hex core gaming laptop just like AMD did. Im looking for a hex core gaming laptop with an Nvidia gpu in it.
