Intel Xeon Silver 4510 vs Xeon 6505P: Architecture Comparison

Q: What is the difference between the Intel Xeon Silver 4510 and the Intel Xeon 6505P?

The Xeon 6505P (Granite Rapids, Intel 3 process) more than doubles the L3 cache per socket compared to the Xeon Silver 4510 (Sapphire Rapids, Intel 7 process): 48 MB vs 22.5 MB, paired with DDR5-6400 for approximately 45% higher memory bandwidth, while both processors deliver 12 cores and 4.1 GHz max turbo per socket.

In OpenMetal’s lineup, the Silver 4510 powers the Medium v4 and the 6505P powers the Medium v5. The 6505P’s base clock is 2.2 GHz vs 2.4 GHz on the Silver 4510, but both reach 4.1 GHz max turbo. For workloads running at sustained high utilization (large relational databases, analytics pipelines, containerized services with large working sets), the 113% cache increase and higher memory bandwidth of the 6505P typically outweigh the 200 MHz base clock difference.

The 6505P adds 88 PCIe 5.0 lanes per processor and three UPI links at 24 GT/s between sockets, compared to 64 PCIe lanesand 16 GT/s UPI on the Silver 4510. The additional PCIe bandwidth benefits high-speed NVMe storage controllers and dual-port 25/100 GbE NICs. TDP is 150 W per socket on both processors.

Both processors support Intel AMX, AVX-512, and SGX. The 6505P also supports Intel TDX (not available on Silver 4510), enabling hardware-isolated Trust Domain confidential computing when paired with 1 TB RAM.
