Intel Xeon W9-3495X “Sapphire Rapids” CPU Sets New World Record, Overclocked To 4.2 GHz & Pulls Over 1000W
The first overclocking performance benchmarks of Intel's Xeon W9-3495X 56-Core "Sapphire Rapids" CPU have been published by Der8auer.

Der8auer used a server-tier motherboard featuring the LGA 4677 socket and for cooling, a 360mm AIO from Cooler Master was used. For memory, there was 192 GB of RDIMM (ECC) modules within an 8-channel configuration were used. The memory was operating at DDR5-5600 speeds.
For the motherboard, an RVP or Reference Validation Platform was used which houses the W790 chipset along with an 8 Phase VRM so it's not the best of the best design for overclocking like the several other W790 motherboards that ASUS, ASRock, Supermicro, and Gigabyte are going to offer but it should do the job well.

The testing was done in a controlled environment at the Intel US HQ with the overclocking team. The Intel XTU (Extreme Tuning Utility) was used to overclock the Xeon W9-3495X CPU "Sapphire Rapids" and the chip itself was pushed to 4.2 GHz across all cores.
What's interesting is that voltage was set to just 1.0V while the processor current limit was pushed to the max of 1023A. The power consumption was around 300-350W at idle and power spikes of over 1000W were reported when the benchmark was running. No temperature numbers were shown but cooling the chip with a 360 AIO may not be the best choice when overclocking these chips.

Despite that, the Intel Xeon W9-3495X "Sapphire Rapids" CPU scored an impressive 53,817 points in the Geekbench 5 benchmark which beats the current world record score of AMD's Threadripper Pro 5995WX in the same benchmark by 12%.Der8auer does state that this is just a teaser of what is going to be possible with overclocking on the new Fishhawk Falls platform and that using proper cooling could yield around 4.6 GHz clocks across all 56 P-Cores and that should deliver even higher performance.

Meanwhile, the default operation of various Xeon W-3400 "Sapphire Rapids" CPUs are evaluated by Pugetsystems which shows that there's still room for improvement as the new Golden Cove cores aren't being utilized properly. Puget systems states they were already being given a new BIOS but they aren't sure how much of a performance increase it would bring to the table.
Overall, we are very excited about these new Intel Xeon processors. Unlike the general public, we regularly have the opportunity to see how performance changes in the weeks and months leading up to a launch, so these results are not as concerning to us as they may be for most of our readers. While it would be great if everything were perfectly optimized this far in advance, reality is often very different. It will be very interesting to compare performance over the next few months to these early initial testing results!
Intel Xeon W-3400 "Expert Workstation" CPU Family
The Intel Xeon W-3400 Sapphire Rapids chips are designated within the "Expert" Workstation CPU family. These chips offer up to 56 cores, 112 threads, 8-channel DDR5-4800 memory support, and 112 PCIe Gen 5.0 lanes. All Intel Xeon W-3400 CPUs support up to 4 TB memory capacities (EEC/R-DIMM).
The top chip within the lineup is the Xeon W9-3495X which offers 56 cores & 112 threads. This chip packs 105 MB of L3 cache and has a base clock of 1.9 GHz & boosts up to 4.8 GHz. The CPU has a PL1 TDP of 350W and a PL2 TDP of 420W.
