The server world will soon be getting a dose of Piledriver, as AMD has announced the Opteron 6300 series. The 6300 series uses the same 32nm chips as the FX-8350, just modified for servers. AMD has designed these as drop-in replacements for the Bulldozer-based 6200 series, just with higher performance and better efficiency. Base and Turbo clocks have increased across the entire line from last year, with parts ranging from four to 16 cores for any requirement. Wattage has remained about the same between the 6200 and 6300 chips, but AMD promises 40% higher performance per watt with the Piledriver ones. Each processor supports 1866MHz memory speeds and even 1.25v modules, and as much as 384GB of RAM and 12 DIMM slots are supported, too. AMD Opteron 6300 chips are available now from SGI, Cray, ASUS, Appro, Colfax, Microway, and more, with Dell and HP expected before the end of the year.
