Server
The Intel Xeon 6517P is a 16-core, 32-thread server processor built on the Intel 3 process, launching in Q1 2025 for two-socket data center platforms with eight-channel DDR5-6400 memory and 88 PCIe 5.0 lanes.
The Xeon 6517P offers 16 cores and 32 threads at up to 4.2 GHz, with 72 MB of L3 cache and a 190 W TDP. It supports eight channels of DDR5-6400 memory and provides 88 PCIe 5.
0 lanes per socket, plus accelerators such as Intel AMX, DSA, IAA, DLB, and QAT. Security features include TDX, SGX, and total memory encryption. Designed for two-socket servers, it targets virtualization, databases, and analytics workloads where I/O and throughput matter more than maximum core counts.

History
The Xeon 6517P arrives as part of Intel’s transition to the Xeon 6 family and the Granite Rapids architecture, consolidating several Xeon Scalable lines under a unified branding and the Intel 3 process.</br>By shifting to a more modular tile design and integrating a suite of data-path accelerators directly on-die, Intel aims to better compete in dense virtualization, analytics, and AI inference scenarios against AMD’s EPYC portfolio.</br>This generation introduces widespread DDR5 and PCIe 5.
0 support, alongside security enhancements such as Intel TDX for confidential computing, reflecting the increasing demands of modern cloud and enterprise data centers.
Improvements over Previous Generation
- Move to Intel 3 process from Intel 7.
- PCIe 5.0 across more lanes.
- Introduction of AMX and data-path accelerators in mainstream SKUs.
