Nvidia claims the Grace CPU Superchip offers 1.5X more performance in a SPEC benchmark than two of the last-gen 64-core AMD EPYC processors in its own DGX A100 servers

We now know the CPU has 72 cores, uses a Neoverse-based design that supports Arm v9

Windows Server 2022 Standard reports as Build 20348 ("21H2") with the familiar Windows 10 desktop - including tiles in the start menu.

The enterprise operating system has been assigned new roles in the future, as it comes with an extended feature set.

DNS-over-HTTPS for DNS resolution
AES-256-GCM / CCM encryption for SMB
Nested virtualization on current processors from the AMD Epyc and Intel Xeon product series
Hyper-V platform in virtual machines
Improved Kubernetes for Azure
Extended container functions

In addition, the Chromium-based Edge completely replaces Internet Explorer and the "old" Edge browser based on the proprietary HTML renderer EdgeHTML in the enterprise sector for the first time .

Also, with 112 cores in a 4P system, that is close to AMD’s 128 core 2P.

Each of the 80 cores is designed to run at 3.0 GHz all-core
, and Ampere was consistent in its messaging in that the top SKU is designed to run at 3.0 GHz at all times, e
ven when both 128-bit SIMD units per core are being used (thus an unlimited turbo at 3.0 GHz)
. The CPU range will vary from 45W to 210W


Ampere has some performance numbers, which as always we take with a grain of salt.
These include 2.23x the performance on SPEC2017_int rate over a single 28-core Intel Xeon Platinum 8280,
and 1.04x over a single 64-core AMD EPYC 7742.
This is obviously extended into a number of claims about improved TCO. Ampere didn’t provide similar numbers for SPEC2017_fp,
because the company states that the SoC has been developed with INT workloads in mind
