That 28-core CPU That Intel Showed At Computex - it needs some cooling!
Early this week Intel announced its 28-core processor at Computex. A remarkable achievement all by itself. They had been able to clock it towards 5 GHz even, boasting a CB 7334 Cinebech score. However, as it now turns out, that CPU needed a bit of cooling.
In fact, the processor was cooled with an industrial chiller. So Intel after the demos quickly dismantled the setup as they had previously installed the 28-core chip on Gigabyte and ASUS demo systems earlier that day. After a few hours, these photos (and I honestly do not know who took it as it went viral everywhere, but credits to you man) have been posted on the web.
I mean, we all understand that 28 cores will need a bit of cooling, but I wasn't expecting that! It's a bit hard to see but that is a Hailea HC chiller and also spotted, a 1600 Watt power supply. 1 That water chiller pumps 1500-4000 liters per hour and uses R134 refrigerant to cool down the coolant towards 4 degrees Celsius. If you look up the specs, it has a cooling power of 1770W. The motherboard was using a lga3647-socket, which is a Xeon processor socket. That's industrial heavy duty cooling. Reportedly the unlocked 28-core proc was a Xeon Platinum Skylake-SP processor. That proc with its default 2.5 GHz clocks does just over 200 Watts in power draw under stress. Try to imagine the numbers when overvolted and tweaked to 5 GHz. In all fairness, it is 28 cores at that frequency.
And sure to place things in a little perspective: above you can see the cooler that AMD used for the demo of their 32-core Threadripper 2 processor. No pun intended.

I mean it's imrpessive that they didn't need LN2 cooling for that CPU, but this is nowhere near what the average PC user will be able to use. So it's still not the CPU with 28 cores and 5GHz that enthusiasts will have at home.

Intel just need to show something so they create that smoke screen
From some time rumor was that AMD will show 24 core Threadripper so they react with re-branded 28 core Xeon. They push trough it 800W of power and they cal it victory over AMD.
Many take that bate at we all read about 28 core CPU at 5GHz, but no one mention that You will need small power plant just to run it, and I am 99,9% sure that we will never see that CPU available to buy.
AMD again winn this battle 32 cores probably at ~4,2GHz and ~300W, at 1/2 price of what ever Intel will offer

they're all about image. It doesn't matter what gargantuan cooling solution they used, 'papers' have written one thing: intel's desktop CPU has 28 cores at 5 GHz.
Pathetic.

That's not happening unless it's on 7nm. I can do you power consumption under full load graph at different clocks today. But following should be enough to extrapolate 8C/16T:
4.2GHz all cores => ~180W
3.9GHz all cores => ~125W
3.8GHz all cores => ~105W
3.6GHz all cores => ~80W
I say that 32C/64T can fit into 300W @3.4GHz and stock 250W limit will put it in 3.0~3.2GHz range once all cores are fully utilized.
Basically, above 4GHz this 12nm+ lithography becomes very inefficient. Zen is good uArch, but it is being held back by manufacturing process. If AMD licensed intel's production capacity, even 1st gen Zen would prove to be King of the Hill.

In fact it does looks like one of those Hailea 800 watts cooling chiller or similar , maybe even heavily moded for more than 800w , chillers can go down to -21c subsero with the right mixture of gases on the compressor. I

A good reminder of why I've decided to avoid Intel when I can.
If that's not false marketing I don't know what is.

I think its possible they could have an all core boost to 3.4,
Threadripper 2 continues the tradition of using highly binned dies, which will skew the average voltage curve down lower compaired to desktop ryzen
dunno how much though.

As with MOST of Intels releases, they are all "paper launches" since way back with the Pentium and the "mythical" 1ghz race, to which they lost by several months.

AMD delivered good CentralPU, intel countered with FridgePU.
