AMD has finally taken the wraps off its upcoming 8-core ARM SoC, codenamed Seattle. Seattle (officially designated Opteron A1100) is a server-class clip, with four or eight 64-bit ARM Cortex-A57 cores. The part, which begins sampling in March, is aimed squarely at the low-power server market, where AMD hopes that the SoC's low cost (about one tenth the cost of competing Intel Xeon parts) can wrestle some market share from Chipzilla. Performance-wise, AMD only gives rough figures, but it appears that the top-end A1100 will be around 2.5x faster than AMD's current low-power Jaguar-based server chip (the Opteron X2150), while maintaining the same TDP.
