Overclocked Intel Sapphire Rapids Xeon Workstation CPUs Paired With NVIDIA RTX 4090 Require Up To 2000W Power

wccftech.com:

Intel's Sapphire Rapids Xeon Workstation CPUs, when paired with NVIDIA's RTX 4090, require up to 2000W power when overclocked.

In the latest tests done by Bilibili's content creator, Extreme Player, we get to see how the latest Intel Xeon Workstation CPUs codenamed Sapphire Rapids perform when paired with a high-end GPU such as the NVIDIA GeForce RTX 4090. Both the flagship Xeon W7-2495X and the W9-3495X flagship chips were tested and most importantly, we got a glimpse of what's the maximum power consumption these chips can sip when they are overclocked.

Starting with the Intel Xeon W7-2495X which features 24 cores and 48 threads, the chip can hit up to 570-600W of power when overclocked to 4.4 GHz across all cores. Moving over to the Xeon W9-3495X with 56 cores and 112 threads, the chip can be pushed to 4 GHz across all cores for the chip to sip in 830-850W of power. The resultant performance from these overclocks is anywhere from a 10-40% jump versus the stock chip with the higher increases witnessed in pure multi-threaded test workloads.

But that's not all, Extreme Player also goes one step ahead and overclocks the Xeon W9-3495X and Xeon W7-2495X Sapphire Rapids Workstation CPUs a bit more to 4.2 GHz and 4.8 GHz, respectively. This yields a 65% and 45% increase over the stock chip within the Cinebench R23 benchmark which is superb.

However, all that extra performance comes at a huge cost in terms of power consumption and the temps. The Xeon W9-3495X hit a 99C at full load while the Xeon W7-2495X hit 104C at full load with the overclocks. As for power consumption, at the final tuned settings, the Xeon W9-3495X hit up to 922W power
