Intel Discontinues 8th Gen Core "Coffee Lake" Desktop Processor Family

Intel today issued a product change notice announcing the discontinuation of its 8th generation Core desktop processor family, and models of Pentium Gold and Celeron processors based on the 14 nm "Coffee Lake" silicon. The PCN covers every 8th gen SKU in the retail- and OEM channels. The company set key dates for the discontinuation. The lineup is discontinued as of June 1, 2020. Suppliers and OEM customers can last order their products on December 18, 2020. The last product shipment is slated for June 4, 2021. It's likely that the 9th generation Core desktop processor family will be follow next year. The 8th generation Core "Coffee Lake" saw the first increase in core counts for Intel's mainstream desktop processor family in close to a decade.

but their spirit carries on
It certainly does. :)

8086K performance below on air-cooling

Yep, it's delidded with liquid metal TIM also binned - still the 8th gen is/was so extremely thermal-efficient. Go 8700K Go 8086K and thank you AMD for bringing them to us. :clap:

5.6Ghz Single-Thread ST benchmarks



5.8Ghz Single-Core only boost



4900Mhz "IMC push to failure"



Daily Work Overclock 5.4Ghz 4500Mhz 17-17-17-37 1.360volts



All on Noctua single bank of fins - C14S $75USD air cooler



Also have to thank Intel for a 2nd binning "the 8086K anniversary editions" in the Summer of 2018. :)

Ain't she a beauty? :)

They should discontinue 10th Gen Core also... Just saying.

lol. Lots of Intel engineers I'm sure feel the same way. lol

They won't discontinue CML by Q4 2020

But they will replace it. RKL coming soon! +20% IPC :clap: (maybe +25%)

I think with gen 9 and 10 that are basically the same chip being fed more power and higher clockspeed, there is certainly no reason to leave so many models out there.

Waiting for 8c16t 9th gen chip to drop in price, although I'm worried my puny miniITX case and LP cooler may not handle the heat

They needed all those 8700k cores for the 10600k/10400

If you take the line out of the middle of an 8 and rotate it, place it in front of the number, what do you get?

and what's the deal with those refreshes



tbh I'd be fine with refreshes,it's understandable when intel is struggling wih 10/7nm nodes and the performance is still good,especially for gaming.it's those damned socket changes.but oh well,I guess it's time for 4.0 anyway,just why the hell not on Comet lake ?

That solves itself, if the refresh isn't worth it anyway, why bother, you can just skip the socket as well.

This is basically the reality for every gamer with an 8th gen CPU. Except if you picked the 8600K

that is very logical.
though I am thinking of getting one.
get a nice z490 and max out on ram, 4400 c19 sticks from viper are tantalizing.get a 10400f,enjoy for a year or two,then lazy upgrade to comet i5 with pcie 4.0 when it's needed,then lazy upgrade to rocket i7/i9 if/when rocket i5 is not enough.

To each his own, but the marginal perf advantage in some games for Intel is not going to last and I'm definitely not going to buy into it in 2020. If its like you say, lazy short term upgrades I suppose it could work...but is that how YOU work? You've been sitting on this 5775C for god knows how long.

I'm honestly pretty convinced that for any long term CPU, Zen is the only platform to buy into. That pertains to security issues and the total stagnation at Intel. This stagnation creates uncertainties in purchase: bad bin CPUs have been a thing since Kaby Lake. Intel is binning so aggressively, you are getting no guarantees of anything more than what's on the box. This, for K CPUs, is unacceptable.

At least with AMD you know the CPU will auto boost to max potential and you can scale your cooling on that more easily, too. With Intel... not so much. The shenanigans are increasing with every release and its not faith inspiring to me. TDP is exploding.

So yeah considerations... but your path doesn't seem logical for someone who has been enjoying Broadwell performance for more than a half decade. Why not just grab a good CPU right away. Its not like progress in CPU is suddenly alive and kicking besides core counts. The performance ceiling is not moving quite so much, especiallyl not if you're not buying top-end stuff (which we both are not).

Thermals are very nice on the 10900K considering (20) 14nm threads, and yea the IMC is improved many 4-dimm boards can now run 4400 and 4600. If someone REALLY can't wait for Rocket Lake or has the funds to buy both, then sure grab Comet Lake and have a blast. lol :D

But I'd wait for an IPC improvement and PCIe 4.0, and possibly even a better IMC with Rocket Lake. Just sayin' :)

And it's not like RKL is 12-18months away, we might see it launch in October. That would be cool.

So upgrade. But an upgrade with the direct plan to upgrade again... sounds silly. There is always the next best thing, who the hell cares... Just get the current best thing instead.

be careful what you wish for,it's not like amd can't ever get sloppy.

Oh I know that all too well :) No choice is definitive... But when I read of different cooling between similar CPUs my alert meter goes to the red. 10th gen is a serious mess, despite its perf.

I'd be on 3600 already if it wasn't for this damned auto boost shenanigans
my pc serves two things - gaming for 1-6 hrs and then sitting quietly for the rest of the day and night.can't accept a cpu that goes into full boost mode when I'm checking my messenger.

Yeah I'd be on Ryzen 4000 to be honest if I had to upgrade now. As for the boosting, everything is tweakable so surely you can tweak out such behaviour too.

Let's continue our slowchat elsewhere lol

you can just let it do 60+ degrees idle is what you can do.
and our discussion is a lot more entertaining than the news itself :roll:

Only really a problem with a stock cooler. If you plan on the stock cooler, yes, it will be a problem.

why ? does a cooler affect boost behavior ?

The boosting issue was addressed some time ago. Right now I've got several instances of Firefox open with several tabs open in each along with Explorer and some other things, jumping around programs and I'm idling at 35°C. Ambient room temp is about 85°F/29°C. Yeah. It's hot in here. lol I'm using a Noctua NH-U14S. In the winter it often drops under 30°C.

It might depending on how hot it gets. I've seen a lot of reviewers say that the stock AMD coolers aren't bad, and maybe they're not to some users (especially if you're on a budget), so when I first built this system I tried it, but I thought it was awful. I built this system with noise as my first consideration, and the Wraith Prism was easily the loudest part in it. Unbearably so. It was either the same day I built it or the next day that I ordered the Noctua. It's whisper quiet and improved on the cooling by about 20°C (idle) for me.

Absolutely, Ryzen's boost is in many ways similar to Nv's GPU Boost in that respect. This is also why it is ahead of Intel's Turbo technology, which keeps adding caveats to achieve higher peak clocks but also gets higher peak temps and voltages. If spiky temps is your fear, Intel is really not the go-to and hasn't been since Kaby Lake, honestly. The complaints are as old as 7700K. It was always manageable, but that is all she wrote. We even delidded the CPUs, remember.

Im experiencing similar with my 8700K. Its a big difference from the 3570K I had before it. The voltages are managed more aggressively and the temps show you this all the time. OCing on this CPU was a temp limited affair, on the 3570K it was certainly not.
