Coffeelake thread, benchmarks, reviews, input, everything.

I purchased mine whilst being fully aware of the 8C; I need the performance now and not down the road - truth be told, as a gaming enthusiast I don't need 8 cores anytime soon and am better off with 6 higher frequency cores. Which, of course, does not mean that I won't drop an 8C in the board simply because I enjoy new advancing technology 😉

Those buying a 6 core right now shouldn't regret it; 9 months is a long time to go.

Although mine's been running less than a day I can genuinely say it's the best CPU I've ever had, thus validating my purchase.

Mainstream socket, 8 core Intel has an unknown arrival date, unknown price increase, and likely unknown reduction in overall clock speed.

I don't think makes any sense at all to wait on so many unknowns.

One thing is known for certain; Intel will release their 8 core chip around the same time or sooner than AMD releases their updated Ryzen chips. If you want to know what Intel is going to do, just watch AMD. Yep, those days are back again. Who knows how long they will stay though. Hopefully for a long time.

You mean Ryzen 2, not Ryzen refresh aka Pinnacle Ridge, right?

Because Pinnacle Ridge is just supposed to be higher clockspeeds, no IPC improvements as far as I'm aware. Don't think Intel really needs an 8C to combat that, technically an 'MCE' enhanced 8700K @ 4.7GHz is enough to match a 4GHz Ryzen 7 in MT workloads. Ryzen 2 is still a year away, you would think AMD would be able to get their IPC up as well as clockspeeds, that will be when Intel needs an 8C chip to compete.

No, I think they'll do it as soon as they can get Z390 ready. They need to get those chips out ASAP, and that platform out doubly so.

 

[jpiniero]

Nope, not according to the latest rumors. Intel moved Z390's release from January to the end of next year. Which between that and the 8 core CFL rumors makes it sound like the 2018/2019 desktop will be more Coffee Lake, with more cores, alongside the Z390.

If that is true, that's disappointing. Intel gonna..

Won't stop me from buying a 6C CL, however.

I thought they moved Z390 to June/July 2018. Which is when 8c/16t Coffeelake should launch.

You think they're gonna try to push out the 8c chip on today's 370 boards? Some of them have the VRMs for it, but it looks like some of them might not . . .

Hi guys

will there be any more CPUs from Intel ?
i5 8600 ? i5 8500 ?
because gap between i5 8600K and i5 8400 is huge in my opinion
base frequencies are 3.6GHz and and 2.8GHz and prices are 255$ and 185$
something has to be in the middle, right ?

This time frame is correct, certainly not the late 2018 someone else mentioned.

Pretty sure they will make those compatible; they can't afford more hate.

But they pretty much run at their turbo clocks all the time, so the difference isn't that large, this Table shows that the difference between 8600K and 8400 is always 300 MHz. Not much room to slip something between. It's really overclocking that make the difference larger.

Intel likes to keep it to a year between releases, so I'd be skeptical of a June/July release. Coffee Lake-X OTOH could get released in June/July. I'd be interested to see if that ends up using the 8 core die.

As for Z370 supporting the 8 core who knows.

Past behavior does not necessarily dictate future behaviour, if you ask me. Intel's own timeline showed June/July and this has been corroborated by respectable reviewers.

Wasn't CFL HEDT off the table?

6 core CFL came 9 months after 4 core KBL. 9 months after CFL would be July.

9 months after July 2018 would be around April/May 2019, which seems like a reasonable launch time frame for Ice.

True but that was an emergency paper launch aimed at destroying Ryzen DIY sales. The real release is in January which would be the typical year.

Icelake on desktop is dead.

OTOH, it took Intel over 10 years to move from 4 to 6 cores on their mainstream socket.

I really don't see them rushing to do it again so soon. 😉

 

[StinkyPinky]

Just out of interest i got 6663 in PC Mark 10 for the 8700k system in my sig, although that's a benchmark for the entire system

 

[VirtualLarry]

I only bought the i3-8100 CFL quad, because it was cheap and available, but it appears that it isn't even a true CFL CPU, rather, just a re-packaged and re-branded KBL die. (Hence the lower DDR4 speed of 2400, just like KBL, but lower than the 2667 of the "true" CFL dies.)

However, I would certainly consider getting an 8-core CFL-X CPU. Although, I think that I just realized that it wouldn't support quad-channel RAM, so perhaps, never mind. I wanted an 8-core Intel CPU, with ringbus, and quad-channel. Though, that may not exist. (Broadwell-E?)

Edit: WTH am I talking about. I like budget chips, not these $1000 monstrosities.

Why? Did I miss something? Last time I heard it was still going strong, so to speak.

That was with a non competitive AMD for a decade though. With Ryzen 2 sporting higher frequencies and improved IPC, a 6 core CFL won't be enough to compete, unless Intel clocks them at 5GHz stock all core turbo (not gonna happen).

Intel's not going to do both the CFL 8 Core and Icelake on desktop. The obvious implication is that yields continue to be so bad on 10 nm that a die that big isn't going to be doable in the timeframe needed.

CFL 8c is likely to arrive in Q3 2018. Ice lake is likely to arrive in H1 2019. The introduction of CFL 8 core is a sign that Icelake is delayed and CFL 8 core should hold the fort till Icelake arrives.

Ryzen 2 doesn't arrive until 2019.

Hmmm I was under the impression it was about a year away, so late 2018. I'm guessing early 2019 is the ETA then?

Everyone gets excited now, like this is some big race, but it is a major investment taping out/masking new chips and companies want to amortize the huge up front costs as long as possible. A full year at minimum.

Ryzen Launched Feb-Mar 2017, I think the earliest anyone expects the refresh Pinnacle Ridge (Ryzen 12nm), is Feb-Mar 2018 (some are saying as late as Q3).

So I don't think Ryzen 2 is expected before Feb-Mar 2019. Leaked Slides show Ryzen 2 in 2019.

The other part of it is that Icelake's clocks are going to be lower, likely enough to wipe out gains from any IPC increase and then some. So Icelake on desktop with an 8 core CFL available would be redundant at best.
