Intel’s Xeon W9-3495X workstation processor features 56 Golden Cove (P) cores running at a peak single-core boost of 4.8GHz. This CPU has a max TDP of 420W with a DTS Max of 99C. An overclocker has managed to push this HEDT chip to an incredible 5.5GHz across all 56 cores. The processor was powered by the ASUS Pro WS W790E-SAGE SE and two Superflower Leadex 1,600 power supplies and got the following result:
The 56-core Xeon W9-3495X scores 132,220 points in the multi-threaded Cinebench R23 benchmark. The system sipped 1,900 watts from the socket and had to be cooled using liquid nitrogen. It operated at a temperature of -95C, preventing thermal bottlenecks from limiting the output performance. The score of 132,220 is the second-highest Cinebench R23 score ever recorded, just 200-something points less than the highest. For added context, this is twice as fast as the fastest 64-core AMD Threadripper, the 5995WX.
