Last year AMD announced it would begin building licensed 64-bit ARM processors as part of the new Cortex-A50 series for its server line. Earlier today the first details of that new series, as it unveiled the Seattle SoCs based on the ARM Cortex-A57. This new line is 64-bit, just like AMD's x86 server chips, and come with either eight or sixteen cores. Each one supports up to 128GB of RAM, features integrated ten gigabit Ethernet (10 GbE), and AMD "Freedom Fabric" technology, which allows for low-power CPU cores to be grouped together into clusters in order to be fed data more efficiently. AMD is planning on both the eight and sixteen-core SoCs to run at 2GHz, with the company saying the ARM chips offer two to four times the performance of the newly announced x86 low-power Opterons.
The Seattle SoCs are expected to begin sampling in the first half of 2014, with shipments set for the latter half. A pair of more tradtional server processors were also unveiled today, with the Berlin CPUs being available in the first half of 2014 and the Warsaw CPUs in the first quarter of next year. The Berlin parts are quad-core chips available in an APU or standalone CPU format, are based on the Steamroller architecture (the second major revision of Bulldozer), and includes support for heterogenous Uniform Memory Access. As for Warsaw, those are twelve or sixteen-core Piledriver CPUs for server motherboard with two or four sockets. AMD claims the Warsaw parts will offer "significantly improved performance-per-watt" than the Opteron 6300 line.
