Three Coffee Lake Processor Specs and Details Revealed

by Hilbert Hagedoorn on: 07/24/2017 09:12 AM | source: | 13 comment(s)

Last week I already showed you a CPU-Z screen-shot of a six-core Coffee Lake processor, this round there is information available on three SKUS.

Coffee Lake (8th gen) six-core processor just surfaced on the web and looking at the hardware registers, it shows is indeed is based on a LGA1151 socket but also shows the fact that it'll be based on a TDP of 80 and/or 95W.

The screenshot last week was based upon an engineering which would have a base clock of 3.5 GHz. Most interesting obviously is the Turbo, and since the multiplier is set at a maximum of 43, thus processor will be running at least two if its six cores at 4300 MHz when it is boosting. The unit has a 12MB L3 cache. Earlier on Canard PC suggested this SKU would be called the Core i7-8700K, but would be based on a 3.7 GHz base frequency, with the i5-8600 at a base clock of 3.6 GHz. So this processor seems to be a different one.

This new diagram however just leaked showing three six cores processors. The presumable i7 8700K with 95W TDP, 3.7 GHz base clock, 4 GHz boost for 4/6 cores, 4.2 GHz for dual core and 4.3 GHz for a single core (likely 2 threads).

Then there will be a 95W part with 3.2 GHz base clock and 3.4 GHz boost for 4/6 cores, and 3.6 GHz boost for 1 or two 2 threads.

The last SKU is a 65W chip with a base clock of 3.1 GHz but 4/6 core turbos to 3.9 GHz. Dual core boost is 4.1 GHz while single core goes up to 4.2 GHz:

This looks quite disappointing really.

Intel gives us back quad core with dual core glued on top of it. So much for innovation and supreme technology.... "sarcasm"

I really didn't expect Intel to give us 6 core i5s I figured they would drop 4cores with ht down to the new i5 and make 6+ cores i7/i9

"The presumable i7 8700K with 95W TDP, 3.7 GHz base clock, 4 GHz boost for 4/6 cores, 4.2 GHz for dual core and 4.3 GHz for quad core (much like the screenshot I mentioned earlier)."

the 4.3 GHz clock is for a single core, according to this diagram.

Well, unless I'm blind there's nothing mentioned regarding threads/HT.

6 cores are fine and dandy but if they actually take HT off of the i5s again a 1600(X) would still look a lot more appealing in contrast.

If they do bless the i5's with HT it'll likely chip away at their used-to i7 margins.

For Intel it appears to be a lose-lose situation currently.

That's because they were stupid enough to introduce another line of processors.
The lineup will be even more confusing now because there'll be more overlap. They should just stick to some basic ****ing rules for each line so the consumer easily knows what he's getting.

Let them lose. They deserve it because of their disgusting i9 shenanigans. I don't know how they have the guts to price those things so high.

Theyre priced that way because theyre the cheapest chips with AVX-512.

The entire LGA2066 platform is compromised and VERY messy compared to what AMD did with Ryzen, Threadripper and Epyc.

AMD has two sockets that span their main x86 product lineup, consumer, datacenter and HPC. Intel has three sockets(LGA1151, LGA2066, LGA3647), Xeon D and some other embeddeds, and TONS of overlap in their product lines. They do tend to compete with themselves since theyve had no competetion for years.

I expect an affordable octacore from Intel when I upgrade in five years.

These clock speeds are looking far more promising than the 3.5-3.9ghz that was shown before. clocking all cores to 4.5ghz should be a breeze. though will be nice to see if there is much IPC change between kaby and Coffee... i will until the reviews come out assume between 5-10% (depending on the application)

I'm also hoping we might with these 6 core processors get a few more PCIe lanes, not sure if any information is out on that if they have increased it to 20/24 lanes instead of the old 16...

Hoping these will be on the ring bus, instead of the new mesh style. didn't really do Skylake X too well in terms of gaming... so hoping we get the ring bus instead

I may be wrong, but they probably can't afford to. Intel design is monolithic, so yields are crap.
AMD on the other hand, just needs 4 cores working to have a viable CPU. Then they "glue" them together with infinity fabric. Hey, whatever works is good for me!

The actual cost of the CPUs is very low compared to their selling prices and their CPUs are actually cheaper than the ones from AMD because they have their own factories.
Intel prices their products high because they know they can sell them for those kind of prices, at least for now. This way they simply make more money selling the same units.

As for those CPUs, an i5 six core capable of overclocking to 5.0Ghz would be fine by me.

HEY! Don't use the word "glue"! ;-) (see those nasty Intel marketing slides that were on the internet recently) Ha

Glue and glueless are terms commonly used in HPC, particularly when describing NUMA interconnects. If Intel is using it negatively thats pretty silly. Nvidia is doing the MCM approach too. Its going to get more common. AMD is ahead of the curve. Intel is behind.

(Yep, they were using that term negatively.)
