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.
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 when heavily overclocked and cooled down using various exotic methods.
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.
