Yes but all AthlonXP1800 ever does is post news that puts anything related to Intel in a good light, then immediately leave. His post is very misleading.

8 core Coffee Lake-S ES at low 3.10GHz clock scored 2212 marks in Cinebench R15 benchmark, faster than 10 core i9 7900X at 3.32GHz clock scored 2184 marks and also completely destroyed 8 core Ryzen 7 2700X at stock clock scored around 1828 marks, 4.4GHz OC scored 1964 marks on Guru3D review and as fast as Jumper118's Ryzen 7 2700X OC to 4.9GHz at insanely 1.679V probably on LN2 scored 2261 marks on OcUK Cinebench R15 benchmark thread.

You will find that 8 core coffee lake on this benchmark works at 5.2 ghz to score that number, not 3.1

It'll be interesting to see if this 8 core chip is a new die (CFL 8+2?) or just a salvaged HEDT part with no onboard GPU and two memory controllers and two cores disabled.

If its the latter then it's likely its been put together in a rush as a response to 10nm issues and Ryzen's refresh, but a CFL 8+2 part would suggest it has been planned for some time.

X299 platform is dead, and the new HEDT uses 3467 socket so they aren't any CFL chips there to cut down.

So the 8 core CFL is just that a new monolithic chip that would run very hot given how hot the 6 core chip runs.

Is this going to be the norm now with intel?
All there upcoming products are going to be previewed as overclocked to give the impression they are better than they are...?

Yes. Look like 8 core coffee lake will be my next CPU to replace 8700K.

Err? Why not just leaving the chips exposed directly to the corresponding coolers, shipping without IHS, just like mobile processors are being shipped?!

Well that leaves a high risk of damage if the die is exposed, especially with beastly metal lumps used in modern air coolers. Plus direct-die cooling isn't as good as you'd think.

...The chewing gum is just a political decision to screw users up. It doesn't force users to upgrade more often.
What stopped users to upgrade after Sandy was the lack of innovation and progress.

Well isn't that what I said? Not soldering the IHS hampers the cooling capability of the CPU, thereby screwing users up. And yes it does force enthusiasts into a position to upgrade more often because if you want the fastest CPU you have to buy the next one, not just overclock the bezeesus out of the one you already have, just like we saw with Sandy Bridge. Ivy bridge brought in PCI-E 3 so that was a worthy upgrade, but even with the minor updates from Haswell onward, there was arguably technology incorporated that would have been attractive to users (not everybody is a gamer, remember).

If they could be cooled properly with soldered IHS and could be overclocked more easily as a result, I think there would have been a larger uptake in upgrades. Perhaps not every generation, but certainly not the 5 or 6 generations gap we've seen.

Its not going to be cheep and will likely be obsolete less than 6 months after it comes out when AMD release Zen2, i bet it uses loads of power as well overclocked like that.

To be honest i cant see the point in going from an 8700 to the 8 core, i would just wait till next years 7nm products.

Yeah pretty much, there's going to be loads of fun and games from Intel the next year or two.

Zen 2 won't make 8 core Coffee Lake obsolete, it'll certainly still have better per-core performance even if it is a crazy buy for the vast majority of consumers. There's little doubt it'll be on another dead-end chipset, require de-lidding, require however many Meltdown/Spectre-like security patches, and use tonnes of power when overclocked (which let's face it, will probably be the only situation where it wins anything).

I also don't see why any gamer would replace an i7-8700K with an i7-9700K (or whatever it'll be called), it'l likely perform the same in the vast majority of titles with the vast majority of GPUs, and that's assuming it can clock as high without needing even more exotic cooling.

sideways14a · 21 Jun 2018 at 14:36

Well maybe not obsolete but very difficult to justify.
I cant see the 8 core coffee being much faster than the 2700, if at all in multithreaded apps unless the snot is overclocked out of it.
But once we are into the 2nd quarter of 2019 Intel wont have the clocks to hide behind when amd moves to 7nm, plus there will be a new core revision and the usual SMT greatness Zen has.
Intel either push forward a new core from the middle of next year, unlikely especially on high core counts, or try and play jack-the-clocks... which with there missfiring 10nm still being troublesome and the 7nm AMD process being used it could end in a lot of disappointment.

True. Even if the 8 core coffee lake is overclocked to 5.2 Ghz, delided etc, there is no GPU to be able to utilise it at 2560x1440 or higher up.
And who would buy a £500 CPU plus £800 GPU to game at 1080p monitor??

Even the upcoming Pascal (aka Maxwel 3) refresh, we shouldn't expect double the GTX1080Ti performance, to conclude with some certainty that 5.2Ghz CLF 8 core could be outpacing the 2700X @ 4.2-4.3Ghz.
Hell I doubt if the xx80 card will be as fast as the 1080Ti, because the gap is pretty big between 1080 & 1080Ti enough to start a new gen fitting stuff between and move the xx70 to 1080 perf.

NV will be happy, pulling an "Intel CPU" performance iteration, the Nvidia worshippers will be happy having something new to brag and ridicule AMD GPUs for, even if the majority will moan about the price.

BIOS tools have revealed that Z370 boards already have a setting for 8-cores.

shamus21 · 25 Jun 2018 at 10:27

looking at the news today the z390 is just a reband so 8xcore should work with out issue on z370 just bios update. Only thing you may have to watch out for is the overclocking mybe a bit hit and miss on the lower end boards.

But for entirely that reason Intel will probably block the 8 cores from anything other than Z390 because only Z390 will have sufficient VRMs to handle the power requirements.

LePhuronn · 26 Jun 2018 at 12:46

Apparently Z390 is being binned off now? Intel can't make the chips because their 14nm fabs are overloaded, so they're strapping 3rd party controllers to the board to get Z390's functionality but just releasing the boards as a Z370 refresh.

https://www.overclock3d.net/news/cp...tedly_scrapped_and_replaced_by_z370_rebrand/1

So this should mean that 8-core Coffees should work on the original Z370. Well, maybe.

RichardH754 · 26 Jun 2018 at 13:00

Looks like there is a good chance Z370 should work with the new 8 cores then!

smilingcrow · 26 Jun 2018 at 13:46

Surely Intel would have known their capacity limit ages ago and it's not as if these chips are large or are made in massive volumes!
If they cancel it the more obvious reason is that it may be cheaper to stick with the older chips.

abui1806 · 27 Jun 2018 at 07:03

Even z170 can work well with 8700K, problem is just the vrm not the chipset itself

And even then, the VRM is only a problem on low-mid end boards. The VRM on my Z170 is better than the equivalent Z370 board.

Panos · 27 Jun 2018 at 18:35

Hmm, I would hold small basket in relation to 8 core CFL working on Z370.
Reason is that Intel apparently is branding the 8 core as i9-9900K, rebrands the 8700K to i7-9700K and the 8600K to i5-9600K.
It wouldn't surprise me if they drop support on the Z370 tbh.
