Intel Xeon W9-3495X OC: Almost 1,900 watts and 5.5 GHz on 56 cores

Record in CB R23 with Xeon W9-3495X

from Maximilian Hohm
Overclocker Elmor overclocked Intel’s 56-core Xeon W9-3495X to 5.5 GHz. In contrast to normal core models, the power consumption explodes to almost 1,900 watts and liquid nitrogen has to be used for cooling. Below you can read more about the OC attempt and the score it was able to achieve in Cinebench R23.

While Intel can continue to stand up to AMD in the desktop area with the Core i9-13900K, the air in the server area is getting thinner for the chip giant. Above all, the efficiency of the CPU architectures and the packing density are a significant selling point, so AMD with a maximum of 96 cores performs significantly better than Intel with 60 cores. This is mainly due to the fact that Intel’s production is still not advanced compared to TSMC, where AMD also has its products manufactured.

Still, it’s impressive what performance Intel can unleash with the inferior manufacturing. This is accompanied by high power consumption, which has now set a new negative record for such systems. The Xeon W9-3495X has 56 cores and an open multiplier with which it can be overclocked. In testing, it was cooled to -92°C with liquid nitrogen by Elmor, an Asus in-house overclocker, and overclocked to 5.5 GHz on an Asus Pro WS W790E Sage SE.

The chip thus achieved 132,220 points in Cinebench R23 and consumed a record-breaking 1,881 watts. In order to ensure the power supply, the test system was operated with two 1,600 watt power supplies, which are typically already oversized individually for high-end systems. The previous Core X generation from Intel achieved a significantly lower power consumption of 1,000 watts with 18 cores, while the 28-core Xeon W-3175X model only ended up with around 700 watts.

The record for the CB R23 is 132,484 points, so this is realistically close with the new Xeon, subject to further tweaks. Of course, such tests are not practical and show once again that all-core OC places extreme demands on the cooling, especially for processors with many cores.
