What the Xeon W-2175 is
The Xeon W-2175 is a fourteen core, twenty eight thread workstation processor from Skylake-W. It launched in October 2017 with a 2.5 GHz base and up to 4.3 GHz Turbo at 140 W. Fourteen cores cover workstations where threads shorten renders.
Nineteen point two five megabytes of L3 cache feed fourteen cores. The 2.5 GHz base keeps power in check, while 4.3 GHz boost keeps interaction brisk. All core loads settle near 3.3 GHz for thermals.
No integrated graphics ship. Quad channel DDR4-2666 ECC up to 512 GB suits large projects. Forty eight PCIe lanes allow multi GPU towers.
Intel priced the W-2175 at $1950 at launch. Studios between 10 and 18 core needs chose it for balanced cost per thread. Locked multiplier keeps fleets stable.
Socket and motherboard compatibility
The W-2175 fits LGA 2066 on C422 workstation boards. Check the board CPU list for 14 core support. Single socket towers scale to 14 cores per box.
Four memory channels and 48 lanes shape high end tower designs. Workstation GPUs take primary slots. The Socket vs chipset: what decides whether a CPU works guide covers C422 planning.
The Xeon W-2195 on the same socket adds four cores. The W-2170B is the Mac Pro OEM counterpart without TXT.
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 long jobs.
Forty eight PCIe lanes feed GPUs and NVMe arrays. Towers split lanes between cards and scratch SSDs.
One hundred forty watts need workstation tower air or liquid. High airflow sustains all core loads.
Upgrade paths
On C422 the step is W-2195 for more cores, reusing board and DDR4.
Past LGA 2066 a new workstation platform is required.
