Intel Xeon W9-3495X consumes 1881W during 5.5GHz overclocking

The Intel Xeon W9-3495X can consume 1881W at an overclock of 5.5GHz, according to a Cinebench benchmark attempt by ElmorLabs. The maximum consumption may be even higher; another overclocking team previously achieved a higher Cinebench score.

The high consumption is evidenced by a Cinebench R23 benchmark video from ElmorLabs using an Intel Xeon W9-3495X clocked at 5.5GHz. At the start of the video, before the benchmark starts, the consumption fluctuates around 300W. The CPU is then cooled with liquid nitrogen to around -93 degrees Celsius.

When the benchmark is started, the consumption shoots up to 1800W, eventually peaking at 1881W. After a few seconds, the benchmark is ready and a CPU multicore score of 132,220 has been achieved. Previously, the Overclocked Gaming Systems team achieved a score of 132,484 using the same processor. The consumption of this has never been shared; the cpu may therefore consume more. This processor was clocked at 5.4GHz. The ElmorLabs system also had an ASUS Pro WS W790E-SAGE motherboard, eight G.Skill Zeta R5 memory sticks, and two Superflower Leadex 1600W power supplies.

Intel announced the Xeon W9 CPU in February. The processor has 56 cores and is intended for use in workstations. The CPU series is the spiritual successor to Intel’s hedt chips in the Core-X series. The previous top model of that series had 18 cores and could consume a maximum of 1000W when overclocked, writes Tom’s Hardware. According to the same site, the Xeon W-1375X with 28 cores could consume a maximum of 700W when overclocked.
