Intel Xeon 6940P Review
Intel Xeon 6940P 72-core 144-thread Granite Rapids server processor, 2.2GHz base / 3.6GHz boost, 288MB L3 cache, 300W TDP, LGA 4710 socket, Xeon 6900P series
The Intel Xeon 6940P is the efficiency-tuned member of the 72-core Xeon 6900P tier, dropping TDP to 300W for operators who need 6900-platform memory bandwidth and core count without the top-bin power draw.
Performance and Architecture
The Xeon 6940P delivers 72 Granite Rapids P-cores and 144 threads at a 2.2GHz base clock boosting to 3.6GHz, with 288MB of L3 cache. It retains full AMX acceleration and PCIe 5.0/CXL 2.0 support, trading some clock headroom for a lower 300W power ceiling versus its 400W and 500W 6900P siblings.
Platform and Deployment
On the LGA 4710 platform, the Xeon 6940P suits density-focused datacenters where rack-level power and cooling budgets are the binding constraint, while still needing the 6900-series memory-channel count for large working-set applications.
Comparison to Alternatives
Against AMD's EPYC 9655 and EPYC 9755 in this catalog, the Xeon 6940P offers a lower-power alternative at a comparable core count, appealing to operators prioritizing power efficiency per rack over absolute peak throughput. Compared to the Emerald Rapids Xeon Platinum 8592+ already in the catalog, the 6940P moves to the newer Granite Rapids platform with more L3 cache and updated I/O at a similar power envelope.
