Earlier today, we covered the announcement of AMD's ARM-based server architecture codenamed Seattle. Following that announcement, AMD laid out the next generation of its x86 server compatible chips.
First up is Berlin which will replace the Opteron 3300 series at the end of this year. From looking at the specifications, Berlin appears to be a server-oriented version of the upcoming Kaveri APU which includes the Steamroller CPU microarchitecture. Berlin will include accommodations for servers including ECC support any internal caches or memory, as well as uniform memory access which is promised by AMD to be the next big thing.
Up next is Warsaw which appears to be a very small update to the current eight-core Opteron chips. It will only be offered in dual-chip package configurations with 12 to 16 cores. Warsaw will be built on a 32nm process and will feature the current Piledriver cores instead of the next-generation Steamroller architecture. It will be socket compatible with the Opterton 6300 series and AMD is promising power efficiency improvements even though it utilizes the older technology.
