Eight core Coffee Lake Processor Finally Spotted?

Eight core Coffee Lake Processor Finally Spotted?

It has been topic of discussion for many months now, ever since the 'Z390 chipset' surfaced on a roadmap and a company kind of leaked that it was intended for an 8-core processor, it became silent though, from the looks of it, it's for real.

Over at Videocardz, they spotted an entry in the Futuremark, and indeed that very much looks like an 8-core processor that is actually listed as Coffee Lake. The processor is listed as a generic, and that means the motherboard firmware microcode has not been updated or recognizing the processor. That base-clock could be misread, or this is a very early engineering sample.

 

 

The Z390 chipset has been spotted on several roadmaps and slides, so at one point we do need to understand what it is intended for eh? Anyway, the CPU is listed at 8-cores and 16-threads, the rest of the stuff looks erroneous, including the listed base clock. The testing platform is listed as Intel Corporation CoffeeLake S82 UDIMM RVP, likely an engineering board.

It will not be released in April though, that moment is for H370 and B360 chipsets and a few new Coffee Lake respin procs, this later. Also, there has been a rumor about the Z370 chipset, it would have been incompatible with Skylake and Kaby Lake due to Intel's preparations for an 8-core CPU.

Make of it what you will, but we're certain of one fact, Intel does not like the fact that AMD has 8-core processors available in the mainstream segment, while they do not.

If they did have an 8 core, maybe they did the sensible thing and got rid of the integrated GPU. A very considerable number of people with Intel processors use them for gaming, so they get the higher spec CPU's. They then use a discrete graphics card and the GPU goes to waste. For businesses, they tend to buy the 'lesser' processors, those that gamers won't buy, so integrated GPU's for them makes sense.

I don't see the need for yet another chipset to support these CPU's, I guess it's so people with 6-core Coffee Lakes buy yet another motherboard to make the most of it :). Also, there's the probability that the CPU will be an okay-ish price considering, but they'll make that up with the cost of the Z390 boards.

If this release is true, it probably means Ice Lake won't be until next year. This in all likelihood is what will happen due to Intel's ongoing issues with the 10 nm node. Therefore, Ice Lake will probably go up against Zen 2. Zen 2 is the first major upgrade to Zen, and is the successor to the yet to be released Zen+. The Zen 2 will supposedly be on a 7 nm node.

Usual Suspects :)
Geekbench 3/4, Luxmark, Cinebench r15, 3D Mark FS Standard. And if you have some game with Benchmark built-in.

I sorted them out based on expected ability to show difference.

All done. Run/tested multiple time to eliminate the variations as much possible.

Also checked with a few other program/benchmarks but difference was either none or negligible.

So, some of the results below I would consider them a "best case" for pointing out differences.

But, in others, yeah, they are clearly there.

P.S: And excuse my horrendous table/format results. :p

Great Work. Geekbench is most interesting. Some of workloads are practically unaffected, and some show even 25% scaling up from 2400 to 3200MHz.
Those which did not scale up are workloads which did not hit memory bandwidth limitation.
Those which did scale up require good bandwidth. Now I wonder for one last test:
May you please disable 2cores in BIOS? And run 2400/3200MHz memory + 4C/8T as controlling sample. (Geekbench only)

Looking at ST SGEMM which is in either case 133GFlops, and then MT scales with bandwidth to:
2400MHz - 504
3200MHz - 630
4266MHz - 710
I wonder if just 4C/8T drop it to theoretical 133*4 = 532. (Maybe geekbench 4 started to support SMT, maybe not.)

Results table in the previous post updated. A GB links also at the end for the 4C/8T.

At 2400MHz the results varied a bit, but I would say you were spot on. :)
