What the Xeon w5-3525 is
The Xeon w5-3525 is a 16-core and 32-thread workstation processor that launched in August 2024 as the Sapphire Rapids-112L refresh for expert workstations. Sixteen Golden Cove Performance-cores with Hyper-Threading and no Efficient-cores give 32 threads at 3.2 GHz base and up to 4.8 GHz boost. Cache is 45 MB of Smart Cache. Processor base power is 290 W, which fits single-socket expert boards with workstation cooling.
The high 3.2 GHz base keeps interactive CAD responsive while 16 cores handle background tasks. Eight-channel DDR5-4800 RDIMM with ECC feeds the die from board memory. Up to 112 Gen5 lanes serve GPUs and NVMe RAID from one socket.
Expert CAD stations with fast interaction fit here. Sixteen cores at high base cover assemblies plus renders together. Buyers who need 20 cores for larger scenes should take the Intel Xeon w5-3535X with 52.5 MB cache instead, since this w5 prioritizes base clocks.
Socket and motherboard compatibility
The w5-3525 fits LGA 4677 on W790 expert boards with 290 W delivery. Boards accept W-3400 plus W-3500 refresh SKUs with a BIOS that lists the part. The FCLGA4677 package uses the E1A carrier.
Memory is DDR5-4800 RDIMM with ECC in 8 channels. Locked multiplier keeps tuning to power limits. Population is 1 DIMM per channel at 4800 MT per s or 2 per channel at 4400 MT per s.
Expert shoppers compare 16-core and 20-core W-3500 parts on cache and turbo. The w5-3525 trails on threads. 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 is the W-3500 standard. Models plus datasets should be sized together. Matched octets are preferred.
PCIe gives 112 Gen5 lanes from the CPU plus 28 chipset lanes for GPUs, NVMe and LAN. Fixed splits mean plans must match the manual.
Cooling is workstation 290 W with vendor-qualified air or liquid. No retail cooler ships with tray supply.
Upgrade paths
LGA allows moves within the vendor list, such as to 20-core W-3500 with similar cooling. Memory and NVMe can also grow. BIOS must support the target.
A working w5-3525 serves expert desks for years.
Frequently asked questions
What socket does the Xeon w5-3525 use?
