Intel: We 'Forgot' To Mention 28-Core, 5GHz CPU Demo Was Overclocked (tomshardware.com) 165

Posted by BeauHD from the how-convenient dept.
At Computex earlier this week, Intel showed off a 28-core processor running at 5GHz, implying that it would be a shipping chip with a 5.0GHz stock speed. Unfortunately, as Tom's Hardware reports, "it turns out that Intel overclocked the 28-core processor to such an extreme that it required a one-horsepower industrial water chiller." From the report: We met with the company last night, and while Intel didn't provide many details, a company representative explained to us that "in the excitement of the moment," the company merely "forgot" to tell the crowd that it had overclocked the system. Intel also said it isn't targeting the gaming crowd with the new chip. The presentation did take place in front of a crowd of roughly a hundred journalists and a few thousand others, not to mention a global livestream with untold numbers watching live, so perhaps nerves came into play. In the end, Intel claims the whole fiasco is merely the result of a flubbed recitation of pre-scripted lines, with the accidental omission of a single word: "Overclocked." Maybe that's the truth, but there's a lot of room for debate considering how convenient an omission this is.

      They didn't explicitly state that it was overclocked because it couldn't possibly be more obvious.

      • As the manufacturer, Intel doesn't get the luxury of showing off overclocked perf. They are obligated to show what they can actually deliver and warranty.

Overclock performance might be interesting to some use-cases, and if it runs stably, I'm not sure you can even say it is overclocking just because it's not running at the most efficient clock speed. Maybe the fancy high TDP setup is the design point and all the other uses are under clocking.

          Why shouldn't they demo whatever speed they want, as long as they don't try to hide the power and support infrastructure required to operate at that speed or use a specially-crafted use case that disguises stability

      I would have assumed this was the case as well, but this is almost certainly one of their Skylake XCC (Extreme Core Count) chips that are used for the high-end Xeon processors that retail for around $10,000 depending on clock speeds. The cores are laid out on a 5 x 6 grid, but two of the spots are used for the memory controller. Here's a site with a good shot of the die [wikichip.org] and a diagram of the parts of the chip.

      I don't know what they intend to charge for this thing, but it's a full chip and utterly massive at almost 700 mm^2. I don't expect it to normally run anywhere close to 5 GHz as one of the tech sites pointed out that Intel was using a stand alone water cooler rated for about ~1700W and that the power supply for their demo was a 1600W job, but even having 28 cores at 3.5 GHz is an insane amount of computational power. I expect it to be priced similarly.
      • I agree with "an insane amount of computational power" but I think of it more in terms of a highly specialized application. For most users diminishing returns as you add cores will likely make the more powerful/expensive CPU not worth it. And for things that could benefit from highly parallel computation a GPU may have a better cost/benefit. Perhaps a virtual machine host would be an appropriate specialized application? Just speculating.

          This wasn't a new chip -- it was a rebranded server chip overclocked to 5 Ghz using external -10 C (14 F) temp cooling system and a modified motherboard that could use non-ECC memory.

          No one would seriously purchase that abomination. It was meant as a distraction and a bit of marketing to compete with AMD's upcoming 32 core Threadripper 2 that was announced shortly after. It was literally a "hey, we got something that can compete with that!" pony show where no one talked about the cooling system needed to overclock it that high -- or even that it was overclocked. Inexperienced reporters ran with a headline that this was a new desktop CPU we might be seeing in the near future. Nope.

          They are already now fessing up that if this thing sees daylight, it won't be stock clocked to 5 Ghz -- you'd be lucky to see it at 3.7 Ghz with boost to 4.2 Ghz on some cores. It's literally nothing new and worse than AMD's threadripper model with more cores and made with a better manufacturing process.

          It's beyond BS when you take a chip already in use in servers, cherry pick one that has the best (almost miracle perfect) overclock capability and use what was basically a refrigerator to cool the water cooling system and hype it as a DEMO for some upcoming product. Tis vaporware to compete on paper with a soon-to-be shipping AMD product.
