OLD NEWS: 12/05/17

Hi guys

Some very interesting info regarding the upcoming Skylake-X/Kabylake-X cpus has been leaked on the anandtech forums by a poster who appears to have inside knowledge of the X299 cpus. Intel will be using i9 labelling for the Skylake-X processors replacing the previous i7 extreme naming of the HEDT parts. All the Skylake-X cpus use X nomenclature at the end of their names.

Intel Skylake / Kaby Lake Thread - 6C/12T Coffee Lake launching August 2017

- L2 cache = 1MB (Skylake-X), 4x as much as Core i7-7700K
- Dual DDR4-2666 for Kaby Lake-X / Quad DDR4-2666 for Skylake-X
- 112W for Kaby Lake-X / up to 160W for Skylake-X
- Apparently all Core i9 parts support AVX-512 (TBC)
- Launch in June, except 7920X (August)

Will share the image you guys want as soon as I'm allowed to.

Interesting that i5 which was rumoured to be on X299 is actually and i7-7640k with 4 threads. The 6 & 8 core parts have only 28 PCI-E lanes whilst the full 44 PCI-E lanes have been relegated to 10 core and 12 core parts. The base clock speeds look pretty good :cool:

.

Just need to know the pricing now.

Calling shenanigans purely based on L3 cache sizes - no other chips have anything other than whole MB's of cache, and can't see how it would work (even if they were harvested from Xeons with more cores e.g. 24 core or 20 core chips) :

Core i9-7920X - 12C/24T - 16.5MB L3
Core i9-7900X - 10C/20T - 13.75MB L3
Core i9-7820X - 8C/16T - 11MB L3
Core i9-7800X - 6C/12T - 8.25MB L3
Core i7-7740K - 4C/8T - 8MB L3
Core i7-7640K - 4C/4T - 6MB L3

The Skylake-X is derived from Skylake-SP Xeon (Purley) and has a new cache structure (1MB L2 & 1.375MB L3 cache per core)

https://techreport.com/forums/viewtopic.php?t=119394

First: Each core now has not 256KB, not 512KB, but 1MB for the L2 cache.
Second: Each slice of the L3 cache is now only 1.375MB compared to 2.5MB in Broadwell Xeon & Broadwell HEDT parts.

The L2 cache has increased from 256KB per core on Broadwell-E to 1MB on Skylake-X. Whilst the L3 cache has been reduced from 2.5MB per core on Broadwell-E to 1.375MB on Skylake-X.

If we divide the Skylake-X cpus total L3 cache by number of cores we get 1.375MB L3 cache per core:

Core i9-7920X - 16.5MB /12C = 1.375MB L3
Core i9-7900X - 13.75MB /10C = 1.375MB L3
Core i9-7820X - 11MB /8C = 1.375MB L3
Core i9-7800X - 8.25MB /6C = 1.375MB L3

Hence the L3 cache sizes are correct

If 7820x 8 core will be 1000£ again it will be a big fail. I can imagine now Intel 8 core is 1000£, 10 core 1500£ and 12 core 2000£! How about that of a plot twist?

Indeed. I am hoping and expecting that this time Intel price these X299 cpus more competitively considering that AMD rumoured HEDT X399 is also coming. If intel stick to old pricing model, I don't think they will sell many.

That actually wouldn't be terrible pricing. I find it hard to believe.

Yup. The above prices do seem on the optimistic side.However imo 7290X for £2000 would be a fail but hoping it does not come to it.

That's the thing we don't know yet and as with anything like this take them with a pinch of salt till we get the official prices.

I like your pricing though. Hope it comes true

Surprisingly this was discussed back in February where reference to upcoming HEDT having more cores was mentioned but it was not clear at the time or it wasn't picked up upon. There was talk of upcoming HEDT having 18 cores but the info remained obscure.

https://www.eteknix.com/intel-introduces-prosumer-xeon-gold-workstation-cpus/

From various unconfirmed reports, Intel is set to launch a new Xeon Gold lineup. These new Xeon Gold CPUs are meant to offer higher core counts than the usual HEDT platform which peaks right now at 10 cores. Users who want more would have to pay a very hefty premium for the E5 and E7s server and workstation class chips. However, there may be many prosumers who simply want a lot of cores without all of the expensive validation and enterprise features. This is where Xeon Gold comes in.

The first chip is the new Xeon Gold 6150 featuring 18 CPU cores, with HyperThreading for a total of 36 logical CPUs. L2 cache comes in at a hefty 1MB per core for 18MB and L3 is 24.75MB. Clock speeds are reported as 2.7 GHz base and 3.7 GHz boost. Of course, we have quad channel DDR4 memory as well. While it falls short of the top end E7 v4 chips which have 24 cores, it is a substantial upgrade over the HEDT platform. I also expect it will have many enterprise features like extra QPI links to be disabled as well as limited to single socket platforms. It will be interesting to see if this rumour turns out to be true and who would need such a CPU.

Now if we go back to the latest slide it mentions TDPs of 165W & 140W for these Skylake-X cpus.

Also we have the leaked Skylake-SP Xeon Platinum and Gold list.

https://hardforum.com/threads/intel-xeon-gold-xeon-platinum-skylake-sp-lineup-leaked.1928015/

Notice that from the list Xeon Gold 6150 is the only 18 core which has TDP of 165W.

This leads me to believe that the Core i9-7980XE is Xeon Gold 6150 repurposed for the X299 platform on MCC die.

Intel will be giving their keynote tomorrow at 2pm Taipei time which is gonna be 7am UK time tomorrow.

https://newsroom.intel.com/news-releases/experience-data-driven-future-intel-computex-2017/

Is there a way we can watch Intel's Computex keynote live tomorrow?

Never thought I would say this, but those prices are somewhat tempting.

Yeah it appears that up to 12 Core; Skylake-X prices are cheaper than Broadwell-E.

Judging by how much info we have on the 10 core part vs the rest I think its fair to say that Intel never had any intention of offering more cores this year if it wasn't for ryzen. TBH if AMD had managed to keep a lid on all the leaks regarding threadripper I honestly think intel would have launched with a 10 core part being the top spec one.

Indeed. In Intel's original Skylake-X plans; 10 core was the main flagship model.

How much would the 7980XE cost speculatively in UK ?

WingZero30 · 1 Jun 2017 at 09:47

mmj_uk said:
About £2k probably, I'm not sure why anyone needs over 8 cores but it's nice to have the option I guess.

Haha I was just curious

So in order to get the UK price we first convert the US price to UK equivalent via the exchange rate and then add the VAT ?? Correct ??

Intel could commercialize a v2 edition of the Socket 2066

http://www.bitsandchips.it/52-engli...commercialize-a-v2-edition-of-the-socket-2066

According to our sources, Intel could commercialize a new version of the Socket 2066 (Just like Socket 2011 → 2011v3), in order to support the 14/16/18 core SKUs.

The new socket will be necessary due to the pretty low TDP (160W) supported by the Socket 2066 (The current Socket 2066 was designed to support up to 10 core SKUs, not 18). The incoming 14/16/18 Skylake-X SKUs will probably have a higher TDP (200W+) in order to work at the highest possible frequencies. Between us, releasing an 18 core CPU that runs just at 2.5 GHz (All Core) could be counter-productive.

This is the main reason why the 14/16/18 core SKUs will be released in 6 months, in our opinion.

LMAO if true and big FACEPALM!!!

This probably explains why X299 LGA 2066 platform was originally designed to accomodate Skylake-X cpus up to 10 cores only. Higher core count cpus (xeon) were domain of the LGA 3647 purley platfrom as intel segmented Xeon from the HEDT platform for Skylake architecture.

By bringing 12+ cores (higher core count xeons repurposed) to X299 they may have to rejig the 2066 platform by releasing v2 motherboards

X99 didn't have this problem as it was designed to accomodate Broadwell-EP 22 cores xeon cpus from the ground up imo.

WingZero30 · 5 Jun 2017 at 22:33

Well Coffee lake-X was leaked few months back and it is expected to top out at 6 cores. Then there is Cascade Lake which is successor to Skylake-SP xeon family.

I think whats going to happen in 2018 or possibly late 2018 with regards to intel HEDT is this:

•Coffee Lake-X would be replacing Kaby lake-X

•Cascade Lake-X would be replacing Skylake-X

WingZero30 · 5 Jun 2017 at 23:50

Yeah Cascade lake appears to be on 14nm ++ aswell. So next year you would still have Skylake refreshes on 2066 platform. The only 10nm die shrink of Skylake I can think of is Cannon lake but iirc this has now been relegated to low powered cpus or mobile chips so I don't think cannon lake would be coming to 2066.

Iirc from intel's manufacturing presentation they showed that 14nm++ offers superior performance to theirs 10nm and 10nm+ ( I don't know how or what benchmark they used in making this comparison). So I suspect that using Skylake refreshes on 14nm++ for HEDT in 2018 makes the most sense performance wise.

This would then lead straight to Icelake/Icelake-X possibly on a new socket (2076??) in 2020. Icelake would mosy likely be built on 10nm+ but because its a new architecture; its likely that Intel would tweak to make its performance better than 14nm++ .

What I have stated above is basically what the trends in discussions have been around the web regarding intel's direction in the future.

Ofcourse a lot of things can change between now and next 2-3 years so anything is a possibility regarding intel cpus.

No one ever disputes that Intel make very good products. Summer of us just dislike their business practices and ruthless pricing in the face of limited competition. Now they have some competition, they'll keep the wealthy and loyal enthusiasts but I suspect the ordinary buyers will jump ship.

This.
