AI / ML
- AMX and AVX-512 provide strong CPU-based AI inference and small-batch training
- Not a replacement for dedicated GPUs or accelerators for large models
- Well-suited for edge inference, analytics, and MLPerf inference workloads
- AMX and AVX-512 provide strong CPU-based AI inference
- Best suited for inference and mid-size models when GPUs are not used
- Large memory capacity benefits model serving and data preprocessing
Content Creation
Gaming
- Server-focused SKU without official gaming benchmarks
- Single-threaded performance is strong, but gaming is not a target workload
- Use desktop or consumer HEDT CPUs for gaming-focused builds
- Server-focused CPU without integrated graphics
- Gaming performance is not a design priority
- Frame rates will be sufficient but not class-leading compared to desktop CPUs

Strengths & Weaknesses
Pros
- 32 P-cores with strong per-core performance and AVX-512/AMX
- 136 PCIe 5.0 lanes for dense NVMe/GPU configurations
- 8-channel DDR5-6400 with up to 4 TB capacity
- Integrated QAT/DLB/DSA/IAA accelerators for storage, networking, and analytics
- 1S platform reduces board and licensing complexity
Cons
- 245 W TDP requires robust cooling and power delivery
- 1S-only; no multi-socket upgrade path
- Not on the densest process node; some EPYC competitors are more power-efficient per core
- No integrated graphics (typical for server CPUs)
- Platform cost is high compared to mainstream desktop parts
Pros
- 32 cores and 64 threads for high multi-threaded throughput
- 336 MB L3 cache reduces memory latency for large working sets
- Eight-channel DDR5-6400 with up to 4 TB capacity
- 88 PCIe 5.0 lanes for substantial I/O expansion
- AMX and AVX-512 improve AI and HPC performance
- Mature server ecosystem with RAS features (SGX, TDX, QAT, etc.)
Cons
- 300 W TDP requires robust cooling and power delivery
- New LGA4710 platform forces a full server/platform refresh
- High platform cost relative to older Xeon generations
- Locked multiplier limits tuning flexibility
- Efficiency at light loads is not a strength

Our Verdict on Each
A well-balanced 32-core Granite Rapids-SP CPU that shines in 1S servers and workstations needing strong per-core performance, massive I/O, and built-in acceleration, though power efficiency lags newer process nodes.
Best for: Single-socket servers, storage appliances, and workstations needing high PCIe lane count and DDR5 bandwidth with moderate core count.
Read the full reviewA powerful 32-core Granite Rapids-SP CPU that excels in memory-bandwidth-sensitive and I/O-heavy server workloads, but its 300 W TDP and platform cost limit it to professional deployments where those features justify the investment.
Best for: Dual-socket servers or workstations running memory-intensive, I/O-heavy workloads such as large databases, virtualization, or AI inference where the 6745P’s cache and memory bandwidth justify the platform cost.
