Intel Xeon 6238R 28-core server processor

This is a new Intel Xeon 6238R server processor with 28 cores and 56 threads. It runs at a base frequency of 2.20 GHz and can reach a maximum turbo frequency of 4.00 GHz. The processor includes 38.5 MB of L3 cache and supports six memory channels with a thermal design power of 165 W.

Suits multi-threaded server workloads needing high

This processor suits deployments that require many parallel threads such as virtualisation hosts, database servers or compute clusters. Buyers who need a lower power envelope or fewer cores for lighter tasks should consider other options. Builders requiring integrated graphics or consumer-platform features will not find them here.

165 W TDP defines cooling and power requirements

The 165 W thermal design power is the key figure that determines the cooling solution and power delivery needed for stable operation. System integrators must ensure the server chassis and power supply can sustain this heat output under full load. This specification decides whether the part fits the target platform.

Questions about this item

How is the Xeon 6238R installed, and what step is often missed?

The processor drops into the server motherboard socket; the critical step is applying the correct mounting pressure in the prescribed sequence so all 28 cores make uniform contact.

What maintenance or replacement will the Xeon 6238R need later?

The 165 W thermal design requires clean heatsink fins and fresh thermal paste every few years; the processor itself has no user-serviceable parts.

What limit appears first on the Xeon 6238R under sustained load?

The 165 W TDP ceiling is reached before the 4.00 GHz turbo can be held across all 28 cores, so clocks settle at the 2.20 GHz base frequency.
