Intel: We 'Forgot' To Mention 28-Core, 5GHz CPU Demo Was Overclocked (tomshardware.com)
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.
/sarcasm Chipzilla would never resort to benchmarking shenanigans ... Oh wait.
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 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.
