Update 06/08: Intel has since backtracked on its initial statements, clarifying that while a 28-core part is coming in Q4 of this year, its stock frequency will not be 5GHz. Rather this was a (very poorly communicated) overclocking demo of the upcoming part. For more details, please see this article.

Alongside the launch of Intel’s first 5 GHz processor, the 6-core Core i7-8086K, Intel today also showcased a 28-core single socket machine also running at 5 GHz. The system on display scored 7334 in Cinebench R15, and Gregory Bryant (SVP and GM of Intel Client Computing Group) explicitly stated that it would be coming in Q4 this year.

No other details were provided, however for it to exist in a current platform, this new processor would likely be in LGA2066 (X299) or LGA3647 (the server socket). Intel technically already makes 28-core monolithic designs in the Intel Xeon Scalable Platform with the Xeon Platinum 8180, which is a $10k processor, which runs a lot slower than 5.0 GHz.

Personally, I feel this new processor is not a higher binned Platinum 8180. Going up from 2.8 GHz base / 3.5 GHz turbo to 5.0 GHz all-core frequency is a big step, assuming the 5.0 GHz value was not an overclock. I would fully expect that this is the point where Intel starts introducing EMIB to CPUs. (ed: FWIW, I disagree with Ian; my money is on a heavily binned 28-core XCC processor made on 14++. We've seen that Intel can do 5GHz on that process with the 8086K)

Last week I discussed the potential death of Intel’s low-end core design for high-end desktop, because it was being eclipsed by the mainstream parts. The only way Intel would be able to reuse the server versions of those low-core count designs would be to enable its embedded multi-die interconnect bridge (EMIB) technology to put two or more of the smaller dies on the same package. This would allow Intel do amortize costs in the same way AMD does by making use of higher yielding parts (as die size goes down, yield goes up).

Intel’s EMIB has a potentially high bi-directional bandwidth, so it would be interesting to see if Intel would bind two dies together and if there is any additional latency or bandwidth decrease with two dies together. With 28 cores, that would subdivide by two to 14-each, but not to four. So this processor is likely to be two 14-core dies using EMIB… which would actually be Intel’s HCC (high-core-count) processor design.

To add something extra to the mix, Intel might not be using EMIB at all. It could just as easily be the QPI interface on package, much how the company is using the Xeon + FPGA products announced recently.

So our primary questions to Intel would be:

  1. Monolithic or multi-die
  2. QPI or EMIB
  3. Socket
  4. Die size
  5. TDP / Power consumption at 5 GHz

TDP is a big part of the equation here. 28 cores at 5.0 GHz doesn’t come for free. The next questions are around price and launch date.



There's the discussion about cutting into Intel's 1P market with such a product. But also, consider that at CES that Supermicro rated their X299 motherboards as supporting 300W processors, so it could easily correlate this processor to LGA2066 and a 300W TDP. That would be... fun... I guess?

    I seriously doubt they'll be able to make Q4 this year. I'd say likely Q2 next year at the earliest. Their track record for being on time has been very poor for the last decade.
  • Tkan215215 - Tuesday, June 5, 2018 - link

    Reason they are not showing much information on spec is they want to buy time. Time is money for every companies and amd threadripper 2 will be releasing soon. In order to stop customers buying amd they hype this. This will give a hugh disappointment T the end just like 10nm. Intel business has been poor market perception and decepting customers. However im surprise big partners and customer still buying their cpu for gaming

    RIP with that idea about specs

  • HStewart - Tuesday, June 5, 2018 - link

    Two very interesting things about this specification

    1. FCLGA1151 - not sure how different then normal LGA1151 chips
    2. Does not have AVX-512 support like the Xeon 8180

    Lack of 512 is significant - it likely why the this cpu can go up 5Ghz

    inb4 some retard buying this just for gaming

    You can bet your money that many enthusiasts sites will not benchmark games and such with anything less than one of these 5 GHz parts, as soon as they're available — regardless of how much they cost to the consumer.

    This is not usual 14nm for sure. I expect ice lake 10nm+ version of it will have the same greatness with additional AVX 512 which can mean twice faster in the workloads it is made for: Content creation.
    It makes GPUs seem some jokes. I believe intel is aiming to let coders switch from CUDA to Intel x86 again.. GPGPU is not best way to do that in fact...

    King of Graphics, AI. and content creation..
  • Oxford Guy - Wednesday, June 6, 2018 - link

    6 GHz or I'm out.
  • ChristopherFortineux - Friday, June 8, 2018 - link

    I am 6 GHz and for that reason I am out.
