Intel's new HEDT CPU leaves behind Skylake-X in terms of power consumption:
Intel's recently introduced Xeon W9-3495X processor packs 56 cores begging you to overclock them, as the CPU also features an unlocked multiplier. When cooled down using liquid nitrogen, the 56-core processor can indeed be pushed to a formidable 5.50 GHz frequency, but at such high clocks it alone consumes almost 1,900 watts, more than beefy high-end gaming PCs, reports HardwareLuxx.
Elmor, a professional overclocker who collaborates with Asus, recently tried to push a Xeon W9-3495X 'Sapphire Rapids-SP' CPU on an Asus Pro WS W790E Sage SE motherboard to its limits with liquid nitrogen cooling. When frozen to -92.8 degrees Celsius/-135 degrees Fahrenheit, the CPU can work at 5.50 GHz and hit 132,220 points in Cinebench R23, which is just a little bit lower than the absolute record of 132,484 points set by another heavily overclocked Xeon W9-3495X. But the result comes at a cost.
The heavily overclocked Intel Xeon W9-3495X processor not only demonstrates phenomenal performance in Cinebench R23, but it also sets record in terms of power consumption. The CPU draws as much as 1,881W power when operating at 5.50 GHz and requires two 1,600W PSUs to feed it.
[...] Without any doubts, hitting 5.50 GHz with a 56-core Xeon W9-3495X processor cooled down using liquid nitrogen is a monumental achievement. Yet, it remains to be seen what makers of boutique factory-overclocked extreme workstations manage to squeeze out of this CPU with a production-grade cooling system and guaranteed long-term stability.

to run more than 50 browser tab with a few trivially simple web-two-oh cloudy applications running in them.
Assuming of course the Xeon W9-3495X machine has TPM. Because if it doesn't, obviously it won't be Windows 11-ready.

Bahhh, you're exaggerating just a little. I can run half a dozen browsers at the same time, with boatloads of tabs open in each. From time to time, I realize that I'm not using some of those tabs anymore, so I close 20 or 30, in one browser, go to the next browser, and close a bunch of tabs, then go to the next browser. None of that puts the least bit of strain on 64 Opteron cores. Qbittorrent uses a couple orders of magnitude more resources than all the browsers combined.
I'll give you a "funny" mod, all the same.

This is a peak power consumption for an all-core frequency that won't ever be encountered in real world use. Businesses aren't going to use liquid nitrogen just to run it at a terrible spot on its efficiency curve.
In reality, it has a base clock of 1.9 GHz, max turbo of 4.8 GHz (1 core), and 350-420 Watt TDP.
Green500 contenders are typically getting most of their efficiency from GPUs, with a small number of CPUs controlling them.
