What the Xeon w9-3595X is
The Xeon w9-3595X is a 60-core and 120-thread workstation processor that launched in August 2024 as the Sapphire Rapids-112L refresh flagship for single-socket workstations. Sixty Golden Cove Performance-cores with Hyper-Threading and no Efficient-cores give 120 threads at 2.0 GHz base and up to 4.8 GHz boost. Cache is 112 MB of Smart Cache. Processor base power is 350 W, which needs workstation liquid or high-flow air cooling.
Eight-channel DDR5-4800 RDIMM up to 4 TB with ECC feeds 60 cores plus multiple GPUs from board memory. Up to 112 Gen5 lanes serve GPUs and NVMe RAID from one socket, which avoids dual-socket licensing for many workstation apps. The large 112 MB cache holds scenes close across many threads.
Expert rendering and simulation flagships fit here. Sixty cores keep the largest assemblies plus builds together. Buyers who need fewer cores with higher base should take smaller W-3500 such as the 44-core Intel Xeon w9-3575X instead, since this flagship prioritizes thread count over base clocks.
Socket and motherboard compatibility
The w9-3595X fits LGA 4677 on W790 expert boards with 350 W delivery. Boards accept W-3400 plus W-3500 refresh SKUs with a BIOS that lists the part. The 77.5 by 56.5 mm FCLGA4677 package uses the E1A carrier.
Memory is DDR5-4800 RDIMM with ECC in 8 channels up to 4 TB. Population is 1 DIMM per channel at 4800 MT per s or 2 per channel at 4400 MT per s. Locked multiplier keeps tuning to power limits and memory profiles.
Flagship shoppers compare W-3500 tops on cores and cache. The w9-3595X leads on both. The Socket vs chipset: what decides whether a CPU works guide explains vendor lists.
Memory, PCIe and cooling
DDR5-4800 RDIMM with ECC in 8 channels up to 4 TB is the W-3500 flagship standard. Huge scenes plus datasets should be sized together. Matched octets are preferred.
PCIe gives 112 Gen5 lanes from the CPU plus 28 chipset lanes for multi-GPU, NVMe and 10 GbE. Splits serve dual GPUs plus RAID on expert boards.
Cooling is workstation 350 W with vendor-qualified liquid or high-flow air. No retail cooler ships with tray supply.
Upgrade paths
LGA allows expert moves within the vendor list, with cooling to match. Memory and NVMe can also grow to 4 TB and arrays. BIOS must support the target.
The mainstream alternative is 4-channel W-2500 for lower cost. A working w9-3595X leads single-socket desks for years.
Frequently asked questions
What socket does the Xeon w9-3595X use?
It uses LGA 4677 on W790 expert workstation boards. A BIOS that lists the refresh is required.
How many cores does the Xeon w9-3595X have?
Sixty cores and 120 threads at 2.0 GHz base and up to 4.8 GHz boost, with 112 MB of cache at 350 W.
What memory does the w9-3595X support?
DDR5-4800 RDIMM with ECC in 8 channels up to 4 TB.
Can the w9-3595X be upgraded?
Yes, within W-3500 on the same board where power, cooling and BIOS allow.
