56 cores and 112 threads support demanding professional content creation, engineering, and scientific workloads.
A 1.9 GHz base clock, up to 4.8 GHz max boost clock, and 105 MB cache provide substantial processing resources for workstation tasks.
DDR5-4800 memory support and PCIe 5.0 connectivity help workstation platforms handle high memory capacity and extensive expansion needs.
The Intel Xeon W9-3495X is a 56-core, 112-thread workstation processor for professional content creation, engineering, and scientific workloads, built on Intel 7 with support for DDR5-4800 memory and PCIe 5.0 connectivity.
The reviewer describes the 56-core processor as a monster that offers impressive performance. However, they note that the high power draw compared to AMD alternatives is a significant drawback, and that clock speeds are constrained by this power consumption. The development of the Sapphire Rapids platform was also highlighted as having suffered from significant delays.
The processor is awarded an editor's pick, assessed as a flagship-tier product with no notable weaknesses and recommended for its category. This editorial verdict is based on manufacturer specifications and public consensus rather than in-house benchmarks.
In an early preview, the reviewers found the 56-core processor to be 24% faster than previous generations in certain content creation tasks. They noted that while it performed exceptionally well in Cinebench, it still trailed behind AMD in other applications. The primary downsides identified were the exceptionally high power draw and the need for further software optimization.
