This week at Computex thus far, we've seen two big CPU-related announcements. The first was the launch of the Intel i7-8086K, a six-core limited edition processor at 5 GHz that is coming out later this week. The second was the behemoth: Intel showed a prototype 28-core system running at 5.0 GHz, and stating that it will be coming out at Q4.

Not a lot else was said, however since the announcement we have dug deep to get some more information, and today we were one of a small handful of press to actually have a chance to get some hands-on with the system on display. Here’s what you need to know.

The new processor runs in the LGA3647 socket, which is Intel’s Xeon enterprise socket with 3647 pins. These processors are huge, and no consumer motherboards exist for them as the design is purely for servers and enterprise. The platform also supports six memory channels, so we have a hex-memory channel design. This was evidenced by the close up images taken from Intel’s Keynote during Computex.

At the keynote, Intel also demonstrated a Cinebench R15 score with the processor running at 5.0 GHz on all 28 cores. The benchmark is a common multi-threaded workload to ramp up all cores to a reasonably high load level. The score in the keynote was 7334 points. Working from data taken from Intel’s current 28-core Xeon processor, the Xeon Platinum 8180, shows that the 8180 at 3.34 GHz can achieve a score of 5040. Doing the math and assuming perfect scaling (which Cinebench does well at) shows that the same processor at 5.0 GHz would score around 7560 points. The difference between that number and the 7334 that Intel scored is within the ballpark, so we are likely looking at an overclocked version of the Intel Xeon Platinum 8180.

In our previous article I suggested that the processor could be two smaller dies connected by EMIB, or through QPI, on the same package. It was, sad to say, wishful thinking, however it is clear that Intel cannot stick to monolithic dies on the latest process nodes forever.

At the keynote, systems from ASUS and GIGABYTE were shown, each looking fairly hefty and bulky. As noted previously, the LGA3647 socket is a server socket and platform, so for this 28-core product to be available to consumers, we will have to see some consumer-grade motherboards coming to market. There is a precedent for this – about 10 years ago Intel released a SkullTrail platform, which used two QX9775 processors in a dual processor motherboard that only Intel produced. That platform was mightily expensive, and hard to acquire – only the big boys had access to it. Chances are we will see the same again here.

On the matter of power consumption – we have seen estimates from our readers about power consumption ranging from 300W all the way up to 1 kW and beyond. Of course this is no ordinary chip, and overclocking it beyond its specifications is going to draw some excessive heat. At the keynote, some zoomed in photographs from our colleagues over at Tom’s Hardware show a very large pile of tubes coming out of the rear of the system. There ends up being two levels of speculation here: either Intel is using a water cooler (likely with a water chiller), or there is phase change cooling in play. The latter relies on sub-zero temperatures, which creates moisture and ice around the socket, and Intel’s demo was fairly clean, so personally I believe that a water chiller is in place. A common water chiller for overclocking can run up to 1500W, although the mid-sized ones are around 500-800W, and can cost a few hundred dollars. That doesn’t give much of an insight into what we are dealing with here, especially as it is an issue about clock speeds.

At the event, Intel said the CPU reached 5.0 GHz, and the tools on display showed a 5.0 GHz reading on all cores. It was not stated if this was overclocked, however most people have come to the conclusion that the processor was. The Intel Xeon 8180 has a base frequency of 2.5 GHz, a turbo of 3.8 GHz, and an all-core frequency of 3.2 GHz. If we allow for the fact that Intel could likely bin this processor higher, around 3.0 GHz base to 4.0 GHz turbo, then we are looking at a substantial overclock.

Pricing is still anyone’s guess. If we take the Xeon Platinum 8180 at $10k, then assume that for consumers it might have the ECC part removed (it can also be binned such that QPI doesn’t need to work). Intel has to be wary about what markets this processor might take away in terms of sales, so it has to be priced accordingly. Add ~$1k for a motherboard that can take the power requirements of a 28-core overclocked beast, and at least 6x8 GB (48GB) of DDR4-2666, then we can imagine that a full ‘base’ system could easily come in at $10k or more. However, for the target crowd, such as high-frequency traders, they would perhaps spend $100k on a bespoke super-cooled system. However many CPUs that Intel wanted to manufacturer (or could even bin), each one would sell, and the people that would want it would be prepared to pay the big money. For anyone looking at a $5k pot for their next high-end gaming PC, unfortunately these parts will be for the 1% of the 1%.

For our sneak peek, we got hands on one of the motherboards that Intel used for the demonstration. According to our sources, only one of the models on display was actually capable of 5 GHz.

This motherboard is a monster. That’s a standard LGA3647 socket, and this is a E-ATX-like (but custom) form factor. Can you see all those phases along the top?

I haven’t had time to count them, this news is so rushed. The VRM cooler was copper finned and had four high-powered fans on it.

There’s plenty of PCIe slots and storage and even some audio, but for a prototype board it is a beast.

We confirmed that Intel was using a water chiller in the 5 GHz demo, a Hailea HC-1000B, which is a 1 HP water chiller good for 1500-4000 liters per hour and uses the R124 refrigerant to reduce the temperature of the water to 4 degrees Celsius. Technically this unit has a cooling power of 1770W, which correlates to the fact that a Corsair AX1600i power unit was being used for the system.

    Yeah, AMD did the same thing with the 1900X. It wasn't that impressive. Reply

    a guy shared similar to this on [H] a few months ago, this is NOT for gaming, it is 100% for Pro use, i.e nuclear simulation etc, boat load of core, boat load of memory, boat load of money to buy it, and boat load of a design team to program the workload for it to run properly.

    there is absolutely nothing "small" about these top of the range systems.

    as for the folks below saying "this is a proper HEDT Threadripper does not compare"

    hmmmmmmm......regular car, high end sports car, indycar, formula 1, top fuel, all of these have a very specific buyer just the same as for example.

    Nv with their "normal" desktop GPU, then they did their Titan cards, then they have their all out pro level cards, TR can game but it was "made for" content creation not gaming on, most games and a desktop environment simply cannot use a crap ton of cores, content creation on the other hand where you might have 5+ high end programs running all at once (video editing, music managing etc) on the other hand can use them.

    would be like a kid who just got their license getting mommy and daddy to buy them a 10,000 hp top fuel racer just to "show off" just because folks do this, that is not the companies who make them at fault.

    TR is a beast, just like what Titan is (though I hate Nv with a passion) there is a tool for every job, then of course there are many tools who do not know what to use them for LOL.

    Loving the tissue-wrappings-and-rubber-bands water-cooling setup. Real hi-tech :P Reply

    Intel has the wrong product on the table to compete with AMD 32 cores HEDT (many motherboards are out for this beast but not one for Intel 28 cores) Reply

    The interesting thing is the extra power inputs. Are those PCI-E graphics power ports?
    If so thats 600W on top of what the ATX spec can supply. Hungry CPU? me thinks so

    This is no rival to threadripper...it's a ridiculous fantasy product, almost a custom boutique product that is in another stratosphere to the price range and set up we will see from threadripper.
    No professional is going to buy one of these and risk overclocking it to 5ghz, it will be used at default speeds...meaning it will have comparable performance to 32 core threadripper in most workloads..at a much much higher price probably.

    Only a lonely millionaire is going to buy this for a gaming setup...0.001% of the market.
    Desperate move from intel who almost look in trouble atm.

    Intel traditionally charges more for HEDT than server on a core count basis as HEDT tends to offer higher clocks.
    So if this has higher clocks and is unlocked, they likely charge more than for the 28 cores Xeon. No 2P on this one but maybe that's not enough of a factor. Won't be cheaper than 10k, unless they adjust server prices down and could go as high as 20k - flagship pricing. This SKU is not about sales, it's more about image so w/e.
    Funny that they didn't had a proper mobo for it, shows this was a late addition.

    I wish this was a 16 Core 5 Ghz Part with Quad Memory Channel. May be some day.

    But I very much hope Zen 2 come out earlier.

    Ugh, I hate watercooling. Reply

    You can see the impact of the giant socket and VRM bank in that the first available spot for a PCIe slot is equivalent to the 4th expansion slot in an ATX board.

    Unless someone can come up with a more compact board layout these are going to require a new board/case form factor to support more than 2 dual slot GPUs.
