AMD has updated its Opteron processors with the Piledriver processing core that was previously introduced for desktop PCs (Vishera, Trinity) and notebooks (Trinity).
The new 6300 series, previously code-named Abu Dhabi, replaces the Interlagos series with Bulldozer core and combines two processor dies in one package. The new Opterons are available with 4 to 16 cores and thermal design power (TDP) levels from 85 to 140 watts.
According to the manufacturer, the 6300 CPUs target virtualized server platforms in private and public cloud deployments, big data systems and high-performance computing clusters. The most significant changes in Pildriver is the upgrade of the Translation Lookaside Buffer (L1-DTLB) from 32 to 64 entries, as well as the additions of a few new instructions that are compatible with Intel's upcoming Haswell chips.
The larger L1-DTLB results in a significant boost in performance in Specjbb2005, a server benchmark used to evaluate Java performance. AMD claims that the Piledriver series are about 24 percent faster than the Bulldozer Opterons in this specific discipline. The processors can be paired with up to four memory channels with up to 1866 MHz memory, low-power 1.25 volt memory, as well as up to 12 DIMMs per CPU for up to 384 GB per processor.
AMD is offering ten different versions of 63xx Opteron processors, including one powered-focused 85 watt model (6366 HE, 16 cores, 1.8 GHz, $575) and one performance model (6386 SE, 16 core, 2.8 GHz, 140 watts, $1,392).
