AI / ML
- AMX and DL Boost accelerate CPU‑based AI inference
- Well suited as an AI host node for GPU‑accelerated servers
- Not a replacement for dedicated AI accelerators for training
- AMX provides hardware acceleration for INT8 and BF16/FP16 matrix operations.
- Well suited for CPU-based AI inference and prototyping where GPUs are not available.
- MLPerf results for Xeon 6 P-core family show ~1.9x AI inference gains vs 5th Gen Xeon, though not specific to this SKU.
Content Creation
Gaming
- Designed for server and HPC workloads, not gaming
- High latency and core‑count‑optimized microarchitecture
- Modern desktop CPUs offer better gaming performance at far lower cost
- No integrated graphics; requires a discrete GPU.
- Server-optimized for throughput, not gaming latency or refresh rates.
- Not a target use case for this CPU.

Strengths & Weaknesses
Pros
- 48 cores and 96 threads for high multi‑threaded throughput
- 8‑channel DDR5‑6400 with MRDIMM support for bandwidth‑intensive workloads
- Up to 88 PCIe 5.0 lanes and CXL 2.0 for GPUs and accelerators
- Mature RAS and enterprise features from the Xeon Scalable lineage
- Good AI inference performance with AMX and DL Boost
Cons
- 300 W TDP requires robust cooling and increases platform power
- High platform cost (CPU, DDR5, server board) compared to lower‑core‑count options
- No integrated graphics; even basic VGA requires an add‑in card or BMC
- Locked multiplier with no official overclocking support
- Overkill for workloads that cannot saturate 48 cores and 8 memory channels
Pros
- 64 P-cores and 128 threads for highly parallel workloads
- 8-channel DDR5-6400 with very high memory bandwidth
- AMX, QAT, DLB, and DSA accelerators for AI, crypto, and data movement
- 48 PCIe lanes (32 Gen5, 16 Gen4) from the CPU
- Intel 3 process improves density and efficiency vs Intel 7
- Strong platform features like TDX, SGX, and total memory encryption
Cons
- High 325 W TDP requires robust cooling and power delivery
- Single-socket only; no multi-socket scaling
- No integrated graphics; not suitable for headless client use
- Premium price point typical of high-core-count server CPUs
- Platform and motherboard costs are significant compared to client CPUs

Our Verdict on Each
A strong 48-core server CPU for multi-socket platforms that need high memory bandwidth and PCIe connectivity, but with a 300 W TDP and premium price that demand careful platform and cooling design.
Best for: Building or upgrading 2–8 socket servers for virtualization, databases, or HPC where high core count, memory bandwidth, and PCIe connectivity are critical and platform cost can be justified.
Read the full reviewA very high-core-count server CPU with strong AI acceleration and massive memory bandwidth, best suited for single-socket consolidation and AI workloads where its power and cost can be justified.
Best for: Single-socket server for AI inference, virtualization, or in-memory databases where 64 cores and 8-channel DDR5 provide a consolidation upgrade over older multi-socket systems.

Which uses less power?
The Intel Xeon 6748P has the lowest rated TDP. Power draw across these chips: Intel Xeon 6748P (300 W), Intel Xeon 6756P-B (325 W).
Do Intel Xeon 6748P and Intel Xeon 6756P-B use the same socket?
No. They use different sockets (Intel Xeon 6748P: FCLGA4710, Intel Xeon 6756P-B: FCBGA5026 (LGA4710 socket)), so each needs a compatible motherboard.
Which has more cores?
The Intel Xeon 6756P-B has the most cores. Core counts: Intel Xeon 6748P (48 cores), Intel Xeon 6756P-B (64 cores).
