AMD has released a benchmark selector and filter tool in order to allow customers to pick what processor platform is right for them. The tool currently supports their four and six core Opteron server families and will soon include the eight and twelve core Opteron 6100 series.
The tool can filter for integer throughput performance of servers using low-power six-core AMD Opteron processors, sort data for mainstream processor models, higher performance SE processor models, and energy efficient HE and EE processor models.
It can also benchmark data by workload application, including virtualisation and compute-intensive high performance computing (HPC) applications.
