Socket FCLGA 4710 12-core server processor

The Intel Xeon 6 6505P is a 12-core, 24-thread server processor built on the Granite Rapids architecture using a 3 nm process. It targets dual-socket platforms that need balanced compute density and memory bandwidth for virtualisation, database and high-performance computing workloads.

FCLGA 4710 platform with DDR5-6400 eight-channel

Verify that your motherboard provides an FCLGA 4710 socket and supports the 150 W thermal design power with an adequate cooling solution, as no cooler is included. The platform requires DDR5 memory running at 6400 MT/s across eight channels to reach the rated 4 TB maximum capacity, and the chassis must deliver sufficient airflow for sustained operation.

All-core 3.9 GHz turbo under 150 W envelope

Under continuous multi-threaded load the processor maintains an all-core turbo frequency of 3.9 GHz within its 150 W thermal design power, while single-thread bursts can reach 4.1 GHz. The 48 MB L3 cache and 88 PCI Express 5.0 lanes help sustain throughput for memory-intensive and I/O-heavy tasks without thermal throttling.

Questions about this item

Does the Xeon 6 6505P ship with a cooling device or must I buy one separately?

The processor is sold without a cooling device; a compatible FCLGA 4710 cooler rated for at least 150 W TDP must be purchased separately.

How do the 2.2 GHz base and 4.1 GHz max turbo frequencies help me choose between this 12-core model and other Xeon 6 SKUs?

The 2.2 GHz base clock gives predictable throughput for steady workloads, while the 4.1 GHz single-core turbo and 3.9 GHz all-core turbo boost burst performance; higher-core-count SKUs typically run lower base clocks, so pick this model when per-core speed matters more than maximum thread count.

What does the 48 MB L3 cache and DDR5 6400 eight-channel memory controller mean for real-world throughput in a dual-socket server?

The 48 MB shared L3 cache reduces inter-core latency, and the eight-channel DDR5 6400 controller delivers up to 4 TB of memory bandwidth across both sockets, feeding all 24 threads without starving the PCIe 5.0 lanes.
