Intel Xeon 6787P Review
Intel Xeon 6787P 86-core 172-thread server processor, 2.0GHz base / 3.4GHz boost, 400W TDP, 172MB L3 cache, Granite Rapids, LGA 4710 socket
The Intel Xeon 6787P is the top core-count LGA 4710 Xeon 6 P-core part in this catalog, the highest-density socketed option before Intel's flagship LGA 7529 platform takes over.
Performance and Architecture
With 86 cores and 172 threads, the Intel Xeon 6787P is the highest core count offered on the mainstream LGA 4710 platform, running a 2.0GHz base clock that boosts to 3.4GHz, backed by 172MB of L3 cache.
Platform and Memory
The Intel Xeon 6787P uses the LGA 4710 platform in a 1S/2S configuration, supporting 8-channel memory up to 2TB (8-channel DDR5-6400). It represents the practical ceiling of LGA 4710 core density before buyers need to move to the LGA 7529 flagship platform.
Comparison to Alternatives
Within the Xeon 6 lineup in this catalog, the Xeon 6787P is the highest-core-count LGA 4710 SKU, ahead of the 80-core 6781P, though the LGA 7529 flagships (6944P/6952P/6960P) exceed it on both core count and memory bandwidth. Against AMD's high-core-count EPYC parts in this catalog, it competes on Intel's AMX/CXL platform features.
