Server processor Intel Xeon 6505P — 12 cores / 24 threads, 2.2 GHz base, 4.1 GHz boost, 48 MB cache, LGA4710, 150 W, DDR5-6400 octa-channel

Intel Xeon 6505P is a server processor based on the Granite Rapids microarchitecture. It features 12 cores and 24 threads with a base clock of 2.2 GHz and a boost up to 4.1 GHz, 48 MB cache and a 150 W TDP. The CPU fits LGA4710 sockets, supports DDR5-6400 in octa-channel configuration up to 4 TB of memory, and provides PCIe 5.0 connectivity with up to 88 lanes. Built-in hardware accelerators and security technologies make it suitable for virtualisation, in-memory analytics and enterprise server workloads.

Advantages

The processor combines multi-core performance and high memory bandwidth through octa-channel DDR5-6400 support and a large 48 MB cache. It includes a wide set of platform features — PCIe 5.0 lanes, ECC support, and multiple built-in accelerators (QAT, DSA, IAA, DLB) — together with advanced security and virtualization technologies such as TDX, SGX, CET and Intel Total Memory Encryption. These characteristics enable efficient handling of demanding server tasks while maintaining data protection and platform resilience.

Suitable for

• Virtualisation and consolidation (VM hosts)
• In-memory analytics and database workloads
• Enterprise applications and multi-socket servers
• Compute- and I/O-intensive server tasks using PCIe 5.0 devices

How to use

Install the CPU into a compatible LGA4710 server motherboard that supports Granite Rapids processors and DDR5 memory. Use appropriate server cooling and a power delivery design capable of handling the 150 W TDP. Populate memory channels according to the motherboard manual to achieve octa-channel operation and install ECC DDR5-6400 modules if needed. Enable platform features (virtualization, accelerators, security options) in firmware or OS as required for your workloads.

Usage recommendations

For best performance in virtualised and in-memory workloads, use a server platform with full octa-channel memory population, enterprise-grade ECC DDR5 modules rated for 6400 MT/s, and adequate cooling. Enable relevant firmware security and acceleration features (TDX, QAT, DSA, IAA, DLB) and keep platform firmware updated to maintain resilience and performance.
