80-core ARM CPU to bring lower power, higher density to a rack near you

Enlarge / "Cloud Native" can also be taken to mean "not for you, unless you plan to buy entire racks full of them." (credit: Ampere)

ARM CPU vendor Ampere announced an 80-core CPU called the Altra on Tuesday. If the core count didn't clue you in already, the Altra is aimed at data-center computing rather than home or even typical business needs. The Altra's 80 cores do not offer hyperthreading, so 80 cores here means 80 threads as well.

Before we go into too much detail about the Altra-which is currently sampling but is not yet generally available and does not have any third-party benchmarks-it's instructive to take a look slightly backward to its little sibling, the 32-core eMAG 8180.

Before Altra, there was (and is) eMAG

The Altra is not Ampere's first entry into data-center ARM computing. Its last processor, the eMAG 8180, is a 32-core part running at up to 3.3GHz turbo. The eMAG 8180 is available in packet.net's c2.large.arm package, in the form of Lenovo's ThinkSystem HR330A 1u single-socket systems.
