CPU Comparison
Intel Xeon 638 Processor vs Intel Xeon 6725P
A side-by-side comparison of specs, performance and value. The Intel Xeon 638 is a 16-core, 32-thread workstation and server processor in Intel’s Xeon 600 Granite Rapids-WS family, built on the Intel 3 process with Redwood Cove P-cores, 72 MB of L3 cache, and 80 PCIe 5.0 lanes. It targets professional workloads like 3D rendering, simulation, and AI inference where high single-thread clocks and decent multi-thread density matter more than maximum core count.

- 180 W TDP and 216 W max turbo can stress compact cooling solutions
- No integrated graphics, requiring a discrete GPU
- Higher platform cost than mainstream desktop CPUs
- Workstation pricing may not justify upgrades for users with existing Sapphire Rapids-WS systems
Pros
- 16 high-frequency P-cores with up to 4.8 GHz turbo
- 192 MB L3 cache and 8-channel DDR5-6400 for memory-intensive workloads
- 88 PCIe 5.0 lanes for flexible I/O and accelerator configurations
- Intel 3 process and chiplet architecture for scalable performance
- Strong security and acceleration: AMX, QAT, DLB, SGX, TDX, MK-TME
Cons
- Higher TDP (235 W) than lower-core Granite Rapids-SP SKUs
- No integrated graphics (typical for server CPUs)
- Locked multiplier limits overclocking headroom
- Premium price segment typical of Xeon 6 performance-core parts
- Core count modest vs some competing EPYC 9005 SKUs at similar price

Our Verdict on Each
A strong mid-range workstation CPU with excellent IPC, modern I/O, and AMX-based AI acceleration, best suited for professionals who need more than desktop cores but don’t require 60+ core monsters.
Best for: Professional workstation or small server needing 16–32 threads, strong per-core performance, and lots of PCIe 5.0 connectivity, but not extreme core counts or eight-channel memory.
Read the full reviewA strong 16-core Xeon 6 SKU for customers who value high per-thread clocks, large DDR5 bandwidth, and extensive I/O over maximum core density, with excellent security and acceleration features for modern data centers.
Best for: Upgrading or building 1S/2S servers where you need strong per-thread performance, large DDR5 bandwidth, and 88 PCIe 5.0 lanes more than sheer core count.
