Information leaked about ARM's plans for five new cores on the 10nm and 16nm FinFET processes. The codenames of these chips are inspired by Greek mythology, it includes Ares, Prometheus, Artemis, Ananke and Mercury.
Ares is a 10nm part designed for the server/enterprise clamshell and large tablet markets, this chip has a power envelope of 1-1.2W per core and will replace the Cortex-A72, while the Cortex-A57 will be replaced by the 10nm Prometheus, which offers a power envelope of 600-750mW per core. Prometheus is designed for flagship phones and tablets, as well as the server/enterprise market.
One of the new things in ARM's lineup will be the introduction of a mid-range segment. The new 16nm Artemis has the same power envelope as Prometheus and replaces part of the A57 and A17 segment. Then you also have the Ananke with a 100-250mW power envelope, which will serve segments that currently use the A17 and A53, as well as the Mercury, a low-end chip with a 50-150mW power envelope. Mercury replaces some A53, A7 and A5 cores.
The only problem with the roadmap is that we have no idea when the new designs will come online. ARM doesn’t even say which node Ananke and Mercury are designed for. Ares and Prometheus are designed for 10nm, while Artemis is supposed to end up in 16nm class designs.
