AMD shared some details about "Seattle", a future chip that will be AMD's first ARM-based Opteron processor. Seattle will use the ARMv8 architecture and will aim at the low-power server market. Full details over here.
In 2014, AMD will once again disrupt the datacenter as x86 processors will be joined by those that make use of ARM’s 64-bit architecture. Codenamed “Seattle,” AMD’s first ARM-based Opteron processor will use the ARMv8 architecture, offering low-power processing in the fast growing dense server space.
To appreciate what the first ARM-based AMD Opteron processor is designed to deliver to those wanting to deploy racks of servers, it is important to realize that the ARMv8 architecture offers a clean slate on which to build both hardware and software.
ARM’s ARMv8 architecture is much more than a doubling of word-length from previous generation ARMv7 architecture: it has been designed from the ground-up to provide higher performance while retaining the trademark power efficiencies that everyone has come to expect from the ARM architecture. AMD’s “Seattle” processors will have either four or eight cores, packing server-grade features such as support for up to 128 GB of ECC memory, and integrated 10Gb/sec of Ethernet connectivity with AMD’s revolutionary Freedom™ fabric, designed to cater for dense compute systems.
