8-core Coffee Lake CPUs Are Surfacing in SiSoftware Database

by Hilbert Hagedoorn on: 05/22/2018 07:24 AM | source: | 24 comment(s)

It's been topic of discussion for a long time now, next to the 6-core Coffee lake Core i7 8700(K), Intel will be releasing an 8-core part to be paired with the Z390 chipset (which Intel quickly removed from their website after posting it).

Intel has been looking for an answer to AMD's 8-core parts for a while now in an effort to release an 8-core part at a more mainstream price, yet is plagued by the swiss-cheese of vulnerabilities of Spectre and meltdown, and the new Spectre variants. It will be interesting to see how Intel will deal with that when the 8-core parts release.

The 8-core part now has surfaced in the SiSoft Database (Sandra) as posted by a user called momomo on twitter, that means that qualification samples are out and very likely, these will be shown at Computex to create some hype and virals. The CPU has been spotted in the SiSoftware database, an 8-core, 16-thread processor has been tested on a "Kabylake Client Platform.

You can see a listed CPU clock speed of 2.6GHz, suggesting that the unknown processor is an Intel test/engineering sample. Clock speeds are expected to be much higher. The cache sizes match as to what you should expect from Intel, 2MB of L3 Cache per processor core. Intel's use of a "Kabylake Client Platform" indicates one thing, it's a socket 1151 design alright.

Most likely still using toothpaste between the die and heat-spreader.

Let's see what Intel will come up with. As wavetrex mentioned, most likely toothpaste again and new socket in classic Intel style..... .

So far my bet goes for Zen 2, but hey, maybe there will be surprises

I do not think that regular toothpaste will do on this chip. They'll use some better TIM this time around. I am not betting on it having soldered IHS, but one never knows.

I was looking forward to this chip, but I honestly expect toothpaste as well. I don't want a chip with paste under the die. With how good the R7 2700X ended up, my current bet is to see what Ryzen 2 has to offer. I'm thinking it will be pretty damn impressive.

There's actually nothing wrong with the stock TIM. However, JayZTwoCents actually did a test with toothpaste for thermal paste and it worked quite well LOL

I think that Intel will use the toothpaste and I also think that the toothpaste will not do. If I remember correctly, they already had massive issues with thermals for their x299 platform, albeit with 10 cores. It's just probably, they will not be able to offer anything in mass consumer price range with soldering (if at all), but maybe they'll at least use better TIM. Also, I'm really interested in the pricing, it can't be that cheap to produce them, as the monolithic 8 core CPU would probably have relatively high failure rates, as opposed to glued together Ryzens.

Standard Ryzen die is 8-cores. Yes, there's two clusters of 4 in it, but it's still a single die with everything on it... 8 cores + L1/2 cache, L3 cache (a lot of it), memory controller, bus interface, etc. It doesn't get more monolithic than that.
What it doesn't have is a shitty iGPU in it which (almost) nobody uses.

There were rumours some time ago about ~5ghz clock rates. I'm a bit sceptical about that, but it will be 7nm after all + newer architecture. 2700x can be pushed to 4.4 with some a lot of OC, however its solid at 4.3. If Zen 2 can reach 4.6-4.8 area that will be very impressive. Slap on top of it AMD"s better PPC and we have a CPU that won't have any issues even at 1080p on very high frame rates.

2 glued and customized 8350Ks. Should be an interesting combination.

Well it seems exactly like dual i3 8350K to me :p Impressive power here.

Easily it could be the strongest CPU for 2018 for every task out there.

There is actually no word on whatever it's CFL or CNL.

Yeah but what will they do about price since the 8700k is $300 Amd is already in the Lead with the 2700x (price wise) no way in heck they sell this for under $400 and even then people will turn to Amd in my opinion unless of course they have that magic 5ghz clockspeed.

Why to wait for new 8 core cpu which needs new MB, if you can now buy 8 core for Socket v2066?

Or you can buy Ryzen 2700X for half the price of that sk 2066 monster and get a properly indium-soldered CPU that doesn't suffer from 10000000 vulnerabilities.

As it is exactly or almost like two i3 8350k specs wise, make the calculations of cost. Plus 50%.

It will cost from 399 € up to 449 euros maximum not more than this because of more expensive z390 mobos.

And you will get Intel under the hood, meaning fastest cpu overall than any ryzen setup.
In theory or after delid. Because Ryzens are outperforming intel's server CPUs with 10C/20T for a while due to TDP as toothpaste is limiting factor.
Then there is question of Dual channel memory with intel chip. I did calculate approximate projections on required bandwidth for workloads in Geekbench.
It was based on very good data delivered by one of our members. And even 6C/12T is already starved by fast ram in certain workloads. In some workloads it would not be bandwidth starved even with slow ram.
But there is no memory allowing 8C/16T to scale properly in those affected workloads on dual channel.
