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
Pros
- 64 cores / 128 threads for heavy multi‑threaded server workloads.
- Large 336 MB L3 cache and 8‑channel DDR5‑6400 memory subsystem.

Our Verdict on Each
A 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.
Read the full reviewA high‑core‑count, memory‑rich server CPU with strong AI acceleration and multi‑socket scalability, best suited for data centers that can exploit its 64 cores and 8‑channel DDR5 bandwidth.
Best for: New or refreshed multi‑socket servers for HPC, AI inference, or large‑scale virtualization where 64 cores and 8‑channel DDR5 are fully utilized.
