Architecture

Redwood Cove (Granite Rapids-SP, Xeon 6, LGA 4710)

Release year

2025

Process (nm)

3

Form factors

Memory type

DDR5-6400 RDIMM, 8 channels

Memory bandwidth (GB/s)

409.6

Bandwidth basis

DERIVED, not a printed Intel bandwidth. ARK lists 8 memory channels and DDR5-6400 only (no MRDIMM line on this SKU, unlike 6787P). 8 x 8 x 6.4 = 409.6 GB/s theoretical peak per socket at 1 DPC.

TDP (W)

350

Unified memory

yes

Consumer part

no

notes

Same 86 cores, 336 MB cache, 350 W and 8 channels as 6787P. The difference is scalability: ARK says 4S/8S, and that is why the 4-socket MLPerf rows (Cisco X410M8, Supermicro SYS-442B-NR) are this SKU and not 6787P. 4S aggregate on llama3.1-8b INT8 is 2068.63 tok/s Offline (Cisco) and 2063.24 (Supermicro) — about 1.7x the 2S 6787P number, not 2x. 2S QuantaGrid D75E-4U is 1170.51 / 516.012. vram_gb null (ARK max 4 TB). RCP $21,280, the glueless-4S tax over the 6787P.
