What the Xeon W-2135 is
The Xeon W-2135 is a six core, twelve thread workstation processor from Skylake-W. It launched in August 2017 with a 3.7 GHz base and up to 4.5 GHz Turbo at 140 W. Six cores at very high clocks cover CAD towers where single thread pace decides interaction speed.
Eight point two five megabytes of L3 cache feed six cores with low latency. The 3.7 GHz base leads workstation parts for responsive modeling, while 4.5 GHz boost leads single thread peaks. One hundred forty watts reflect high sustained clocks.
No integrated graphics are present. Quad channel DDR4-2666 ECC up to 512 GB suits large assemblies with error cover. Forty eight PCIe lanes allow workstation GPUs plus NVMe storage.
Intel aimed the W-2135 at clock sensitive workstations above the W-2133. Engineers who model interactively all day benefit more from 3.7 GHz than from extra cores. Locked multiplier keeps behavior consistent.
Socket and motherboard compatibility
The W-2135 fits LGA 2066 on C422 boards with ECC support. X299 HEDT boards do not enable ECC workstation features. Check the C422 CPU list for stepping.
Four memory channels and 48 lanes shape single socket tower designs. Workstation GPUs take primary slots. The Socket vs chipset: what decides whether a CPU works guide covers C422 planning.
The Xeon W-2133 on the same socket trims clocks where cost matters. The W-2155 adds four cores where rendering grows.
Memory, PCIe and cooling
DDR4-2666 ECC in four channels up to 512 GB is the design. Matched quartets hold quad channel bandwidth for large models. ECC corrects single bit errors in long sessions.
Forty eight PCIe lanes feed professional GPUs and fast scratch arrays. Single socket towers split lanes between graphics and NVMe. Board manuals detail sharing.
One hundred forty watts cool with workstation tower air or liquid. Sustained high clocks need steady airflow.
Upgrade paths
On C422 the move is W-2155 for more cores or W-2145 for threads plus clocks, reusing board and DDR4. The gain shows in render and simulation times.
Past LGA 2066 a new workstation platform is required. ECC memory often carries across where DDR4 remains.
