Codenamed Seattle, the chip will use ARM’s 64-bit ARMv8 architecture. With Seattle, AMD hopes to repeat the success of its first 64-bit x86 Opteron parts from a decade ago. The focus is on dense server space and power efficiency. The ARMv8 architecture more than doubles the word-length compared to the previous ARMv7 instruction set. Seattle parts will feature four to eight cores, with support for up to 128GB of ECC memory, Integrated 10Gb/sec Ethernet connectivity.
Seattle is for clearly for networks, but AMD points out that it is in a unique position to ship mixed racks with 64-bit ARM chips and traditional 64-bit x86 parts. This should allow the company to leverage the power efficiency and networking prowess of Seattle with upcoming x86 Opterons that will do most of the heavy lifting.
