Overclocking: Intel Xeon W9-3495X sets records at almost 2,000 watts


The news is currently making the rounds that Intel's Xeon W9-3495X has reached a power consumption of a whopping 1,881 watts in an overclocking session. A new record was also set in Cinebench 23 a week ago with the same processor.

The origin of the reports on extreme power consumption is the following video from ElmorLabs on YouTube, which contains excerpts an overclocking session at Asus. The new Intel Xeon w9-3495X from the Sapphire Rapids generation with its 56 cores was overclocked using liquid nitrogen. The Asus Pro WS W790E-SAGE SE was used as the mainboard and the power supply was provided by two 1,600 watt power supplies.

New Cinebench 23 world record

With a clock of around 5.5 GHz on all 56 cores, the Xeon w9-3495X achieved a whopping 132,220 points in Cinebench R23. That's almost a world record, because the bar was raised to 132,484 points with the same CPU on March 8th. That's another 9 percent more than the 121,215 points, which is the current highest score with an overclocked AMD Ryzen Threadripper Pro 5995WX with 64 cores.

Intel is clearly in the lead per core with around 2,366 points vs. 1,894 for AMD, but the Threadripper does not yet use AMD's current Zen 4 architecture, but its predecessor Zen 3. With the appearance of Threadripper 7000 aka Storm Peak, it is practically certain now , that the record mark will go to AMD again, because everything points to up to 96 cores, which will also perform better and clock higher.

Until then, the new Xeon will collect but other records and currently also leads in Cinebench R20, Y-Cruncher, 3DMark CPU test and Geekbench 3 as reported.

Fast 1,900 watts in the benchmark

During the benchmark, the power consumption was recorded, which, according to the display, reached a whopping 1,881 watts at its peak. According to the entry in the ranking list, a single 1,600 watt power supply unit was sufficient for the current AMD record with the 5995WX overclocked to around 5.4 GHz, so the power consumption should have been much lower. However, the editors could not find any information on the actual power consumption of the overclocked AMD CPU.
