At this time last year, the most energy efficient AMD Opteron^TM processor-based server (based on the SPECpower^TM_ssj benchmark) could achieve only a score of 203 overall ssj_ops/watt (95,853 ssj_ops & 276W @ 100% target load) and consumed 164W at Active Idle. A server using the newest Six-Core AMD Opteron HE processor achieved a score of 1228 overall ssj_ops/watt (419,277 ssj_ops & 221W @ 100% target load) and consumed only 120W at Active Idle¹. That’s more than 6x the performance-per-watt AND more than a 25% drop in Active Idle power.

AMD technology-based servers help increase performance-per-watt and decrease power consumption at the same time by using a suite of features we call AMD-P. AMD-P is supported by the Six-Core AMD Opteron 2400 and 8400 Series processors as well as the Quad-Core AMD Opteron 2300 and 8300 Series processors. This suite of features and the large number or processors that support them enable customers to build energy efficient two-socket, four-socket, and eight-socket servers which can efficiently meet the needs of almost any server application.

When we compare servers using the newest Six-Core AMD Opteron 2400 Series HE processors to servers using existing AMD Opteron processors, we find that a server based on the AMD Opteron 2400 Series HE processor is able to achieve 18% higher performance-per-watt than a server using Quad-Core AMD Opteron 2300 Series HE processors² and also consumes 18% lower platform-level power than a server using Six-Core AMD Opteron 2400 Series processors³.

That’s a pretty big improvement over a processor that was released just six months ago!

In addition to lowering server Active Idle power and boosting server performance-per-watt, these new Six-Core AMD Opteron HE processors are designed to provide significantly more processing performance than prior low-power AMD Opteron processors. Servers using these processors are able to achieve up to 50% higher performance than servers using Quad-Core AMD Opteron 2300 Series HE and 8300 Series HE processors in the same power and thermal envelope. That’s like getting the performance of V6-powered Ford Mustang and the fuel efficiency of a four-cylinder Ford Fusion in the same car.

Whether they’re being used in a cloud cluster or a High Performance Computing cluster, the newest AMD Opteron HE processors provide plenty of performance for only a few watts.

What do you think – is a cloud a cluster or is a cluster a cloud?
