Intel Xeon 6738P Review
Intel Xeon 6738P 32-core 64-thread server processor, 2.9GHz base / 4.2GHz boost, 210W TDP, 64MB L3 cache, Granite Rapids, LGA 4710 socket
The Intel Xeon 6738P matches the 6737P's class-leading 32-core clock profile, offered as a parallel qualified part number for system integrators standardizing on Intel's high-clock Xeon 6 tier. It pairs 32 cores and 64 threads with a 2.9GHz base clock that boosts up to 4.2GHz, backed by 64MB of L3 cache.
Performance and Architecture
With 32 cores and 64 threads, the Intel Xeon 6738P shares the 6737P's high 2.9GHz base / 4.2GHz boost clock profile and 64MB L3 cache, built on the same Granite Rapids performance (P-core) silicon.
Platform and Memory
The Intel Xeon 6738P uses the LGA 4710 platform in a 1S/2S configuration, supporting 8-channel memory up to 2TB (8-channel DDR5-6400). As with the 6730P/6731P pair, the choice between 6737P and 6738P usually comes down to OEM qualification and supply availability rather than performance.
Comparison to Alternatives
The Xeon 6738P is functionally identical to the 6737P in this catalog, giving system integrators a second qualified part number at the premium 32-core clock tier. Against AMD's EPYC processors in this catalog, both compete on Intel's AMX/CXL platform features and mature enterprise software ecosystem.
