NVIDIA’s own 4nm CPU scores exceed Ali’s 128-core CPU

NVIDIA announced the Grace CPU server processor last year, which is a 144-core ARM processor, and at the hotchips conference, NVIDIA announced the architecture details and scores of Grace. Intel's x86 flagship, but also more than the recently taken the first Ali Yitian 710 processor.

Grace CPU was previously said to be a 5nm process, but now it is confirmed to be a 5nm modified version of the 4nm custom version, with a single core up to 72 cores, 144 cores under dual cores, 117MB L3 cache (234MB under dual cores), internal chip interconnect bandwidth up to 3.2TB/s, support for 68-way PCIe 5.0, support for 16 channels of LPDDR5X memory, bandwidth over 1TB /s, C2C-NVlink bus bandwidth up to 900GB/s, 7x the performance and 5x the power efficiency of PCIe 5.0.

In addition, NVIDIA also announced the performance of Grace CPU, single-core 72-core SPECrate2017_int_base performance is 370 points, under the dual-core up to 740 points, parallel efficiency is very high, basically a linear increase.

The hardwarexxx website aggregated multiple SPECrate2017_int_base scores, and the 740-point SPECrate2017_int_base performance is currently the highest, not only far ahead of AMD and Intel's 36-core or 64-core x86 processors, but also more than Ali's Yitian 710.

Yitian 710 is Ali's own 5nm 128-core ARM server processor, which was the first in SPECrate2017_int_base with 510 points, but now it is normal to be surpassed by NVIDIA's 144-core CPU, after all, NVIDIA's design is more horrible in memory and interconnect architecture.
