What the Xeon W-2133 is
The Xeon W-2133 is a six core, twelve thread workstation processor from Skylake-W. It launched in August 2017 with a 3.6 GHz base and up to 3.9 GHz Turbo at 140 W. Six cores cover mainstream workstations where responsive modeling matters more than high thread counts.
Eight point two five megabytes of L3 cache feed six cores. The 3.6 GHz base sustains interaction well, while 3.9 GHz boost lifts single thread peaks. One hundred forty watts suit tower workstations.
No integrated graphics ship. Quad channel DDR4-2666 ECC suits assemblies with error cover. Forty eight PCIe lanes allow a professional GPU plus fast storage.
Intel aimed the W-2133 at mainstream workstations above quad core parts. Small teams pick it for CAD without high core cost. Locked multiplier keeps behavior uniform.
Socket and motherboard compatibility
The W-2133 fits LGA 2066 on C422 boards. X299 lacks ECC workstation support. Check the maker CPU list.
Four memory channels and 48 lanes shape tower builds. The Socket vs chipset: what decides whether a CPU works guide covers workstation planning.
The Xeon W-2135 on the same socket adds clocks. The W-2145 adds two cores where threads help.
Memory, PCIe and cooling
DDR4-2666 ECC in four channels up to 512 GB is the design. Matched quartets hold quad channel bandwidth. ECC protects sessions.
Forty eight PCIe lanes feed graphics and NVMe. Towers balance GPU and scratch per manuals.
One hundred forty watts cool with workstation air. Airflow decides sustained pace.
Upgrade paths
On C422 the move is W-2145 for clocks and cores, reusing board and DDR4.
Past LGA 2066 a new platform is required.
