History
Intel’s Xeon workstation line evolved from the HEDT-focused X-series into the W-2400/W-3400 families using the Sapphire Rapids architecture on the Intel 7 process, introducing up to 56 cores and eight-channel DDR5. In August 2024, Intel announced the W-3500 and W-2500 series as a Sapphire Rapids refresh, adding more cores and cache at each tier and positioning the 60-core w9-3595X as the flagship for expert workstations. This refresh retained the LGA4677/W790 platform and kept the same PCIe 5.
0 lane counts and memory capabilities, focusing on incremental performance uplifts while adding support for advanced accelerators like AMX. The launch reflects Intel’s strategy to maintain competitiveness against AMD’s Threadripper PRO series in professional markets, particularly for workflows that benefit from high core counts and massive I/O expansion.
Improvements over Previous Generation
- Four additional cores (60 vs 56) and higher thread count.
- Larger L3 cache (112.5 MB vs 105 MB).
- Slightly higher base frequency (2.0 GHz vs 1.9 GHz) and increased max turbo power to accommodate boost.
