Recently we shared the mining performance of the Rocket Lake-S flagship, the Core i9-11900K which supposedly performed on par with the GeForce RTX 2060 in Ether mining (turned out to be Venus hash in the end). While fairly impressive, the high power draw due to the use of AVX512 made the whole endeavor rather pointless. Today, we have info regarding the mining performance of two not one Intel Xeon Ice Lake-SP processors (24 core x2).
Two 24 core Xeon Gold processors manage to generate just 1.99 USD per day, with a speed of 17,299 kH/s in RandomXmonero. While that’s pretty low, the thing that really makes this whole endeavor obsolete is the fact that the two processors drew a whopping 580W, while making a ton of noise.
Strangely, the miner only used half of the CPU cores (no hyperthreading was utilized) which is primarily due to the bandwidth-intensive nature of the workload. Each Xeon core has just around 2.5MB of L3 cache while the Ryzen 5000 parts come with 4MB of L3 cache per core.
AMD’s Ryzen 9 5950X didn’t perform much worse with daily profitability of $0.75 (slightly less than half as much as the Xeon duo) despite packing just a third of the core count. This once again can be explained by the large L3 cache available to the Zen 3 parts.
For reference, the 5950X attained a speed of 9.468 kH/s in Xmonero, slightly more than half of the Xeon Duo’s 17kH/s
