AMD has reported that in actuality this chip should rarely hit 250W, essentially only if overclocked. As with the Ryzen 2 lineup, overclocking can actually hurt performance.

But you are correct that some of the more budget-oriented (and I use that term loosely) TR4 boards will struggle with power delivery. Worst case, you will shorten the lifespan of your motherboard and increase the risk of capacitor failure (eg: shorting, popping, etc).

I'm somewhat curious about what kind of cooling system Intel was using the other day with their 28 cores at 5 GHz demo/stunt. Some people isolated a frame of the streamed video where it shows the (insulated?) pipes that exit from the case and go behind the desk.

Edit: grammar

Water cooling with a chiller - water was close to freezing temperature.

Most popular way is to use arctic fish aquarium chiller

Anandtech also has an article on that.

It's fine for showing off of far the chip can go, but nothing someone would have under the desk.

In addition to the overwhelmingly slap-dash appearance, its power draw was reportedly through the roof (north of 750W). With that chip, a fully-loaded workstation's power draw would exceed the wattage of most North American wall outlets.

Suffice to say, Intel's 5GHz 28-core chip is nowhere near production-ready and their demo is more than likely a heavily overclocked top-binned Xeon chip. In other words, Intel's new offerings are looking like less than stellar vaporware.

Threadripper 1 still beats the pants off of Intel's HEDT offerings in terms of price (Intels' costs quickly exceed the $5K mark), Threadripper 2 twists knife so much that its a gaping wound in Intel's side. The Epyc 2 lineup will similarly affect Intel's enterprise/data-center offerings.

I was pretty sure it was mostly for show and not a feasible product but nonetheless I was guessing around 500W. Without counting the chiller running under the desk.

People have been saying some form of subambient cooling, phase change or similar.
