AMD has released a new range of Opteron processors, a mix of quad-core, 8-core, 12-core and 16-core parts ranging in clock speeds from 2.3 GHz to 3.5 GHz.
According to the data released by AMD, these new processors will offer a 37 percent 'uplift' compared to the 6200-series. The processors all feature AMD's second-generation modular core architecture codenamed "Piledriver" that allows for higher performance, and better price/performance, than the 6200-series.
All processors are manufactured using 32-nanometer architecture and feature a Socket G34 1944-pin LGA. They all have 16 MB L3 cache, four HyperTransport links, 2MB of L2 cache per core, and a quad-channel memory controller that supports RAM up to DDR3-1600.
As far as enterprise users are concerned, one feature of the new 6300-series parts will be socket compatibility with existing processors. This means the new processors are a drop-in replacement for the 'Bulldozer' Opteron series, even keeping the same TDP levels, which range between 115W and 140W for all but the high efficiency (HE) 16-core part. This allows companies to extend the life of existing hardware.
Even on paper there's a black mark against these processors. While the new processors offer a performance boost of about 7-8 percent, they cost about 10 percent more than the previous silicon. Even when the power saving is factored in, it is not clear that these parts offer strong value.
This launch comes hot on the heels of AMD announcing that it had licensed ARM technology for server processors. AMD plans to manufacture 64-bit server processors based on ARM's Cortex-A50 series designs beginning in 2014.
