What the Xeon W-2104 is

The Xeon W-2104 is a four core, four thread workstation processor from Skylake-W. It launched in August 2017 with a fixed 3.2 GHz at 120 W. Four cores without Hyper-Threading cover entry workstations where ECC memory matters more than threads.

Eight point two five megabytes of L3 cache feed four cores. The fixed 3.2 GHz keeps behavior simple for fleets. One hundred twenty watts reflect workstation voltage delivery even at modest clocks.

No integrated graphics ship. Quad channel DDR4-2400 ECC up to 512 GB suits entry assemblies with error cover. Forty eight PCIe lanes allow a professional GPU plus storage.

Intel priced the W-2104 at $255 at launch as the entry Skylake-W. Small offices chose it for ECC without high core cost. Locked multiplier keeps it stock.

Socket and motherboard compatibility

The W-2104 fits LGA 2066 on C422 boards. X299 lacks ECC workstation support. Check the C422 CPU list.

Four channels and 48 lanes suit single GPU towers. The Socket vs chipset: what decides whether a CPU works guide covers workstation planning.

The Xeon W-2102 on the same socket trims clocks where cost matters. The W-2123 adds Hyper-Threading for multitasking.

Memory, PCIe and cooling

DDR4-2400 ECC in four channels up to 512 GB is the design. Four DIMMs hold quad channel mode. ECC protects long sessions.

Forty eight PCIe lanes feed graphics and NVMe. Entry towers use one professional GPU. Board manuals detail sharing.

One hundred twenty watts cool with workstation air. Steady airflow sustains fixed clocks.

Upgrade paths

On C422 the move is W-2123 for threads or W-2133 for cores, reusing board and DDR4.

Past LGA 2066 a new platform is required.
