Quick Verdict
A strong 38-core SoC with modern I/O and DDR5, ideal for dense edge and single-socket entry servers; not for gaming due to lack of integrated graphics and high TDP.

Market
Server
The Intel Xeon 6563P-B is a 38-core server SoC in the Xeon 6 family, offering four DDR5 memory channels, PCIe Gen 5 and Gen 4 I/O, and a 235 W TDP for entry-server and edge workloads.
The Intel Xeon 6563P-B delivers 38 performance cores and 76 threads, 152 MB of L3 cache, and a 2.4 GHz base with up to 4.0 GHz turbo, backed by four DDR5-6400 memory channels and mixed Gen 5/Gen 4 PCIe lanes.
It's designed for single-socket deployments where I/O and throughput matter more than per-clock efficiency, though at 235 W you need adequate cooling and power delivery.

Architecture Overview
Granite Rapids-D is Intel's single-socket SoC family within Xeon 6, tuned for edge and entry-server workloads by integrating compute, I/O, and accelerators into one BGA package.
CPU Design
The 6563P-B implements 38 performance cores (P-cores) with Hyper-Threading (76 threads), a unified 152 MB L3 cache shared across cores, and a 2.4 GHz base frequency with a 4.0 GHz all-core turbo.
Memory Subsystem
Four memory channels support DDR5 up to 6400 MT/s with ECC for higher bandwidth and reliability versus prior-generation DDR4 Xeon E parts.
PCIe & I/O
The SoC provides 48 PCIe lanes split between Gen 5 (32 lanes) and Gen 4 (16 lanes), allowing high-speed NICs, GPUs, or SSDs while retaining compatibility with Gen 4 devices.
Overclocking
The multiplier is locked, consistent with server SoC products targeting stable, validated operation rather than enthusiast overclocking.
- Much higher core counts up to 38 cores
- DDR5 memory support with higher bandwidth
- PCIe Gen 5 lanes alongside Gen 4
- Integrated accelerators for networking and media on select SKUs
Key Highlights
- 38 performance cores with 76 threads
- DDR5-6400 support across four channels
- PCIe Gen 5 and Gen 4 lanes for flexible I/O
- ECC memory support for server reliability
- SoC integration suited for edge appliances
- No integrated graphics
- High 235 W TDP requires robust cooling
- BGA package is not socket-upgradable
- Multiplier locked, no enthusiast overclocking
- Market-focused; overkill and overpriced for typical desktop usage
History
The Xeon 6563P-B arrives as part of Intel's Xeon 6 push for entry servers and edge infrastructure, succeeding the Xeon E-2400 family by adopting DDR5, PCIe Gen 5, and higher core counts. Intel's public materials list the codename Granite Rapids-D during development, and Q1'25 as the launch window. The 6563P-B targets single-socket, space-constrained platforms that still demand significant compute and I/O bandwidth, reflecting the industry's shift toward more capable edge appliances.
By packaging 38 performance cores into a BGA SoC with four memory channels and mixed Gen 5/Gen 4 PCIe, Intel aims to bridge the gap between dense edge deployments and traditional rack servers.
Improvements over Previous Generation
- Much higher core counts up to 38 cores
- DDR5 memory support with higher bandwidth
- PCIe Gen 5 lanes alongside Gen 4
- Integrated accelerators for networking and media on select SKUs
