Coffee Lake info leaks - a six core i5?

TDPs and Clock speeds are also leaked.



Read more on Intel's potential 6-core i5 Coffee Lake CPU.

Ehm isn't this kinda old news Mark? One leaked months ago.

It's also what I have been posting in the quick news thread for months as well

If they launch at these clocks anno 2017 it's embarrassing. I know base doesn't matter to us overclockers but still. All I want is a decent and at least 4.5-4.6GHz boost clock to lazily enable all core turbo in the BIOS and maybe only fiddle with lowering the voltage.

Additionally, CFL will use a ring bus as it's a continuation of KBL and not a grand new design AFAIK. Hopefully this is true and we'll also get a the normal cache divisions as we already know = good for gaming

New leak:

Intel Coffee Lake Core i5-8250U, 4 cores, maximum 3.4 GHz, in Acer Swift 3: http://laptopmedia.com/news/intel-core-i5-8250u-is-coming-acer-swift-3-to-get-it-early/

While there were a few results from one a while back this data is much more comprehensive, with data on cache sizes, clocks and TDP information.

It will be interesting to see what kind of performance trade offs there are with Coffee Lake. Will Coffee Lake use a Ring Bus or a Mesh architecture? What will pricing be like between i5/i7 4/6 core CPU models? Looking forward to that launch whenever it happens.

- I've updated my post.

These cache sizes were also in my posts from the leaks. The entire article from your source is directly and entirely derived from those same leaks. However, this is unimportant. I came in here hoping for more and newer leaks. Craving for more

I wonder why the 4.2GHz 6C/12T part wasn't mentioned in neither your source's or your article? I could live with those out of the box clocks and OC myself, with the above mentioned laziness be damned ha ha!

Yeah, I agree with you there. Most of this information is already out there from various leaks, that is the thing with releases like this. Love seeing your enthusiasm on the Quick News thread, are you looking to upgrade to Coffee Lake yourself?

I could post an article about every small leak, but a lot of these things are best suited to a wider roundup every once in a while unless a new leak offers transformative amounts of information. Then there is the problem of whether or not any specs are read wrong by benchmarking programs, which is common.

I agree with your comment on the Ring Bus, as Mesh makes no sense at lower core counts, it is designed for high-level Xeons and has no real place in the mainstream. It offers higher latency at lower core counts but vastly better latency at higher core counts, IE, Ring bus is good at quickly taking to fewer cores and fails at higher core counts while Mesh is better at handling large core counts but not as good in smaller packages.

TLDR, Mesh is not suitable for the mainstream, Ring bus is faster until it scales to colossal core counts.

Absolutely, every small leak isn't worth its own news story and the occasional round up makes more sense. If you're looking to incorporate the 4.20GHz screenshot let me know and I'll look it up for you as these things tend to get lost among posts. While realising that such software can read specs incorrectly on unreleased hardware, there's no doubt in my mind the HT 6C will at least release with those frequencies.

Indeed, the mesh architecture was a much needed change in the server department for the high core count Xeon parts, and simultaneously it left X299 in an awkward place - at least for those who game on it as well - further indicating that HEDT is really becoming a full blown workstation segment member.

Yes I will upgrade to Coffee Lake-S 6/12 now that X299 makes no sense for my needs. Mostly I want to get HT back (the 6700K was way overpriced for months here in the Netherlands and thus too expensive for me when I built this system), and having two more cores appeals to me as well for those couple of game titles that are coded to use them. Ideally my plan is loosely this: Coffee Lake-S 6/12 > Tiger Lake-S 8/16 (just because) > Sapphire Rapid-S (if this is the new revolutionary design that brings actual benefits for my usage, and not least, if SHR won't be server only. If it is then replace the name with whatever comes directly after TGL-S or the optimization that comes after that).

Normally only GPUs get my blood pumping faster but recently CPUs started to excite me as well, being on the prowl and all. And I like the Quick News thread a lot, nice place for quick tech update snippets.

Finally moving on from quad cores. It's about bleeding time !

I recall thinking, after purchasing a Q6600 shortly after release, 'I'll get 6 cores next, and that won't be too far off!' ... and here we are, years have passed I, for one, cannot wait and still dislike it not being next month for a hard launch because I have some time off I could've partially used building it. A Saturday in a windy and rainy October weekend will have to suffice. (I already cringe at the thought of reinstalling and tweaking Windows again - it's tied to your account now rather than the BIOS isn't it? I'll be using the same account+license as now.)

I remember buying an AMD Phenom II 1090T (my favourite CPU ever), when I was in my first year of uni back in 2011/12. I remember wondering how long it will be for 6-cores to become common. I am still waiting...

Before that, I used an Athlon II X3 Triple core CPU, great CPU for the £45ish pounds I spent.

Still got my 1055T. Some one gave me one (ooer !) about 18 months back and it's under water running Ubuntu. Might get a DDR3 board though.

Not really.
We are still *ucked by Intel screwing people over by selling dual core i7s. Sure it's mobile. But it's still slow. Heck even dual core i3s are long in the tooth.

It's taken way to long to move on from dual cores.

Just in case:

I always felt Skylake was going to be the next big leap forward. I never expected it would AMD to make that leap before Intel.

According to the original article this should be the top part of the line up:

Core i7-8700K 6C/12T 3.7 GHz base, 12MB L3, 95W
Core i7-8700 6C/12T 3.2 GHz base, 12MB L3, 65W
Core i5-8600K 6C/6T 3.6 GHz base, 9MB L3, 95W
Core i5-8400 6C/6T 2.8 GHz base, 9MB L3, 65W
Core i3 gets 4C/4T

Canard PC Hardware says Coffee Lake is compatible with 200-series and some 100-series motherboards. Up until late June I heard it would be 300-series only, but great news if true.

Thanks Sweepr!

Pers. comm. I doubt it will work with anything other than the 300 series.

Well it all comes down to price. This can be amazing, or really crap.
I hope Intel starts a battle in the gamer/consumer segment, but i doubt it :/

Yeah my Macbook is a dual core I5. LOL they're tossers.
