This Sapphire Rapids CPU consumes 1.9 kilowatts during OC
Intel next-gen HEDT platform also known as Sapphire Rapids WS/112L/64L has only been released last month, but this was enough time for overclockers to claim multiple world records already.
The Xeon W3400X series excel at multi-threaded workloads, finally surpassing AMD Ryzen Threadripper in some of the longest standing world records. But records aside, Intel CPUs also have much higher TDP than consumer models, going as high as 350W with default TDP, and even higher when used for advance multi-threaded workloads.
As a reminder, the “X” series in the Sapphire Rapids-WS lineup are enabled for overclocking. Those CPUs are now used by known overclockers, such as Elmor or Der8auer who are occupied taking things to a next level. They are now using Xeon W9-3495X CPU, a flagship Sapphire Rapids SKU with 56 cores. The CPU was put on ASUS W790E-SAGE SE motherboard and equipped with G.SKILL Zeta R5 DDR5 memory designed for this platform.
What they achieved was 5.5 GHz clock speed on all cores, which of course required exotic cooling such as liquid nitrogen to keep the CPU under negative 95 degrees Celsius. More importantly, the CPU reached a peak power consumption of 1881 watts, a power consumption that exceeds the most powerful consumer gaming systems under load (with graphics).
Unfortunately, in this case the score that was achieved (132220 points) was not enough to beat Elmor’s last week record of 132484 points. One can only imagine how much power did the CPU require during the previous test.
