12-core Xeon workstation processor

The Intel Xeon W-3235 is a 12-core server CPU built for professional workstation workloads. It operates at a base frequency of 3.3 GHz with a maximum turbo frequency of 4.40 GHz. The processor features 24 threads and 19.25 MB of L3 cache. It is designed for the Socket 3647 platform and requires a compatible Intel C620 or C621 series chipset.

19.25 MB cache and 24 threads for parallel tasks

The 12 cores and 24 threads provide substantial headroom for multi-threaded applications such as rendering, simulation and data analysis. The 19.25 MB L3 cache helps reduce latency when working with large datasets. A thermal design power of 180 W means sustained heavy loads will demand robust cooling. Single-thread performance tops out at the 4.40 GHz turbo ceiling.

Socket 3647 mounting and 14 nm manufacturing

The processor uses the Socket 3647 interface, which dictates a specific motherboard and cooler mounting pattern. Its physical dimensions are 3 inches wide by 2.2 inches deep. The 14 nm process technology underpins the 180 W TDP rating and a maximum operating temperature of 72 °C. Compatibility is limited to Intel C620 and C621 chipset-based workstation boards.

Questions about this item

Will the 3.3 GHz Xeon W-3235 run on my existing C621 chipset motherboard with Socket 3647?

Yes, the processor is listed as compatible with Intel C621 chipsets and uses the Socket 3647 interface.

How can I verify the 12-core CPU is hitting its 4.40 GHz overclocking speed under load?

Monitor core frequencies with a hardware utility while running a multi-threaded workload; all 24 threads should reach the rated turbo frequency if cooling handles the 180 W TDP.

Does the box include a heatsink for the 180 W TDP or must I buy a Socket 3647 cooler separately?

The processor ships without a heatsink; a compatible Socket 3647 cooler rated for at least 180 W must be purchased separately.
