This Intel CPU Has 86 Cores

While impressive, Intel's new Xeon 6500P and 6700P processors represent a step down from the flagship Xeon 6980P's 128 cores. However, their key advantage lies in broader system compatibility. Unlike the 6900P series, these "scalable" SKUs support four and eight-socket platforms, offering greater flexibility for data centers. The range also includes models with as few as eight cores.

These processors also differ in memory support. The 6500P and 6700P support eight DDR5 channels, compared to twelve on the 6900P series; both support MRDIMM technology. I/O capabilities also vary, with the newer chips offering up to 88 PCI Express 5.0 lanes (versus 96 on the 6900P) and four UPI 2.0 links (compared to six).

Crucially, the Granite Rapids architecture maintains feature parity with the 6900P, including AVX-512 and AMX support, ensuring consistent software compatibility across the Xeon 6 family. This is a significant advantage in server/workstation environments.

The significant drawback is cost. The high-end Xeon 6787P (86 cores, 3.8GHz turbo, 350W TDP) carries a hefty $10,400 price tag. The Xeon 6788P, with identical specs but eight-socket support, commands a staggering $19,000. Even the lower-end eight-core Xeon 6507P costs $765—comparable to Intel's Core Ultra 9. These prices, typical for this class of chip, effectively rule them out for non-server applications. And remember, even more powerful 128-core models are on the horizon.
