The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Strong multi‑threaded throughput for server workloads; actual performance depends heavily on memory and I/O subsystem design.
No verified PassMark or SPEC CPU2017 results available for this specific SKU; performance should be similar to other 64-core Granite Rapids-SP parts.
Gaming
Not a target workload; single‑thread performance is modest and platform is not optimized for gaming.
Not intended for gaming; no relevant benchmarks available.
Virtualization
Excellent for consolidating many VMs per socket thanks to high core count, large cache, and 8‑channel DDR5.
No published VMmark or virtualization benchmarks for this exact SKU; design and core count suggest strong VM density.
Efficiency
330 W TDP is high; performance per watt is competitive only when the cores and memory bandwidth are fully utilized.
No verified performance-per-watt data; 325 W TDP is high but typical for 64 performance cores in this generation.
Specialized Performance
AI / ML
- Intel AMX and AVX‑512 provide significant acceleration for matrix‑heavy AI workloads.
- Well‑suited to CPU‑based inference and feature extraction where GPUs are not deployed.
- Performance depends on software stack using AMX and MRDIMM/DDR5‑6400 bandwidth.
- AMX (Advanced Matrix Extensions) accelerate matrix operations for inference and training
- No dedicated GPU, but strong CPU AI and QAT/DLB/DSA acceleration for data movement and compression
Content Creation
Gaming
- Server‑focused platform with no integrated graphics and limited value for gaming builds.
- Single‑threaded clocks are modest compared to client‑oriented CPUs.
- Not recommended for gaming‑centric use cases.
- Server-focused SKU with no integrated graphics
- Gaming performance is irrelevant for this use case

Which uses less power?
The Intel Xeon 6768P-B has the lowest rated TDP. Power draw across these chips: Intel Xeon 6768P (330 W), Intel Xeon 6768P-B (325 W).
Do Intel Xeon 6768P and Intel Xeon 6768P-B use the same socket?
No. They use different sockets (Intel Xeon 6768P: FCLGA4710, Intel Xeon 6768P-B: FCBGA5026 (LGA 4710)), so each needs a compatible motherboard.
