AMD’s First ARM CPU To Begin Shipping In The Second Half Of 2015

by Khalid Moammer 4/20/2015

AMD announced at its Q1 2015 earnings conference call that the company will be shipping its first ever ARM powered CPU this year. More specifically in the second half of 2015. The chip in question is the eight core A57 powered server processor code named Seattle. Seattle began sampling last year and according to AMD has so far managed to become the most used platform for ARM based sever development. Seattle is primarily targeted towards servers and the embedded market. It was in fact believed for a long time that this chip would be a perfect fit for dense servers. However AMD’s recent exit from that market indicates that this may not have been the case and that a shift in philosophy is taking place at the company.

AMD Seattle Features 8 ARM A57 Cores 12MB of Cache and Dual Channel Memory Interface:

Seattle is built on Globalfoundries 28nm process node. It features an eight core design based on the 64bit ARM A57 CPU cores. The chip features 1MB of L2 cache per core pair and 8MB of shared L3 cache accessible to all cores. The chip features support for ECC DDR3 memory with speeds of up to 1866Mhz running on a dual channel memory interface. Seattle also features an ARM security processor and a cryptographic coprocessor. The TrustZone technology enabled by the ARM security processor allow for sensitive tasks to be processed interdependently from the the A57 cores isolating them from any possible security risk.
