Xeon W9-3495X processor requires 1,900 Watts

So much for energy conservation 

While companies are churning out press releases about how they are saving polar bears by greenwashing their operations, Intel has put out a processor which could make the lights dim in parts of Texas if it is ever turned on.

Of the bat, Intel's recently introduced Xeon W9-3495X processor is super powerful. Its 56 cores scream for over clocking and when cooled by liquid nitrogen, it can reach speeds of 5.50 GHz.

But according to Toms Hardware the chip consumes almost 1,900 Watts which is more than beefy high-end gaming PCs.

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 tad lower than the 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 also set 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.

For comparison, Intel's previous-generation Core X-series processors with up to 18 cores could consume around 1,000W, whereas Intel's extreme workstation-oriented 28-core Xeon W-3175X drew up to around 700W.
