Performance and power efficiency of Dell PowerEdge servers with E5-2600 v2Executive summaryIntroductionDell PowerEdge and PowerEdge C servers are now available with the Intel Xeon processor E5-2600 v2product family, code named “Ivy Bridge-EP”. These new Xeon processors feature up to 12 cores and arefabricated on a 22-nanometer process for improved power efficiency.In order to show customers the performance and power efficiency improvements that E5-2600 v2 processorsbring to PowerEdge servers, Dell’s Solutions Performance Analysis team performed a series of benchmarksusing the new processors then compared the results to those obtained using the Intel Xeon processor E52600 product family, code named “Sandy Bridge-EP”.Based on the results of performed testing, PowerEdge servers with E5-2600 v2 processors perform 23% to50% better and have as much as 52% better power efficiency, compared to the same servers running E5-2600processors.Key findingsPower efficiency with E5-2600 v2 The PowerEdge R720 is the world’s most power-efficient server, achieving a 54% higher overall scorein the industry standard SPECpower ssj2008 benchmark with two E5-2660 v2 processors. The PowerEdge M620 is once again the world’s most power-efficient blade server, achieving a 51%higher overall score in the industry standard SPECpower ssj2008 benchmark with two E5-2660 v2processors.Performance with E5-2600 v25 The PowerEdge R720 server with two E5-2697 v2 processors supported 50% more virtual desktopsusing the industry standard Login VSI benchmark. The PowerEdge R620 server with two E5-2697 v2 processors achieved 48% higher gigaFLOPSrunning the Linpack scientific-computing benchmark.

Performance and power efficiency of Dell PowerEdge servers with E5-2600 v2MethodologyTo highlight the performance improvements gained by PowerEdge servers running E5-2600 v2 processors,few configuration changes were made between those runs and the runs with E5-2600 processors that wereused for comparison. However, as PowerEdge servers with E5-2600 v2 processors support up to 16 DIMMsrunning at 1866MT/s, that speed memory was used in most benchmarks, except as noted in Appendix A.6

Performance and power efficiency of Dell PowerEdge servers with E5-2600 v2Integer performanceSPEC CPU2006 integer testsThe industry standard SPEC CPU2006 benchmark is described on SPEC.org as:CPU2006 is SPEC's next-generation, industry-standardized, CPU-intensive benchmark suite, stressinga system's processor, memory subsystem and compiler. SPEC designed CPU2006 to provide acomparative measure of compute-intensive performance across the widest practical range ofhardware using workloads developed from real user applications.The integer portion of the benchmark is particularly good at measuring a server’s ability to run generalbusiness applications. In Figure 1, we see a 41% improvement in the SPECint rate benchmark with E5-2600 v2processors.Figure 1: Performance improvement running SPECint rate base2006SPECint rate base2006100093880041%600666R620 with E5-2697 v2R620 with E5-269040020007

Performance and power efficiency of Dell PowerEdge servers with E5-2600 v2Even the SPECint base 2006 benchmark, which only runs a single copy of each benchmark, benefits with theupgrade to E5-2667 v2, as seen in Figure 2.Figure 2: Performance improvement running SPECint base2006SPECint base2006(higher is M620 with E5-2667 v2M620 with E5-2680

Performance and power efficiency of Dell PowerEdge servers with E5-2600 v2Java server testsThe SPECjbb2005 and SPECjbb2013 are also useful for measuring a server’s ability to run general businessapps. As described on SPEC.org:SPECjbb2005 (Java Server Benchmark) is SPEC's benchmark for evaluating the performance of serverside Java. SPECjbb2005 evaluates the performance of server side Java by emulating a three-tierclient/server system (with emphasis on the middle tier).SPECjbb2005 is a multithreaded benchmark, and as Figure 3 shows, scores 42% higher with E5-2697 v2.Figure 3: Performance improvement running SPECjbb2005SPECjbb2005 score(BOPS, higher is 00500,000091,493,52942%M620 with E5-2697 v2M620 with E5-2680

Performance and power efficiency of Dell PowerEdge servers with E5-2600 v2SPECjbb2005 was retired on October 1, 2013, for the newer SPECjbb2013 benchmark, which is described asfollows:A usage model based on a worldwide supermarket company with an IT infrastructure that handles amix of point-of-sale requests, online purchases and data-mining operations.As Figure 4 shows, the performance improvement with SPECjbb2013 is 33%.Figure 4: Performance improvement running SPECjbb2013SPECjbb2013 score(SPECjbb2013-MultiJVM max-jOPS, higher is 0,00001042,43133%R720 with E5-2697 v2R720 with E5-2690

Performance and power efficiency of Dell PowerEdge servers with E5-2600 v2Floating point performanceSPEC CPU2006 floating point testsFloating point performance is important to those running science, simulations and HPC workloads. SPECCPU2006 contains a suite of floating point tests which when in “rate” (multithreaded) mode, show a 39%performance improvement with E5-2697 v2, as seen in Figure 5.Figure 5: Performance improvement running SPECfp rate base2006SPECfp rate base2006(higher is better)80070068160050040030020010001139%491T620 with E5-2697 v2T620 with E5-2690

Performance and power efficiency of Dell PowerEdge servers with E5-2600 v2SPECfp base2006 runs a single copy of each benchmark. In Figure 6 we see a 26% performanceimprovement with the E5-2667 v2 processor.Figure 6: Performance improvement running SPECfp base2006SPECfp base200612010410082.88060402001226%M620 with E5-2667 v2M620 with E5-2680

Performance and power efficiency of Dell PowerEdge servers with E5-2600 v2HPC performance testsThe Linpack benchmark is used to measure a system’s floating point processing power by solving linearequations. We ran the Intel Optimized Linpack Benchmark against a single node using both generations ofprocessors. The E5-2697 v2 shows a 48% performance improvement, as seen in Figure 7.Figure 7: Performance improvement running LinpackLinpack performance(gigaFLOPS, higher is 0.013R620 with E5-2697 v2R620 with E5-2690

Performance and power efficiency of Dell PowerEdge servers with E5-2600 v2SPEC OMP2012 is another scientific computing benchmark, described on SPEC.org as:SPEC OMP2012 is designed for measuring performance using applications based on the OpenMP 3.1standard for shared-memory parallel processing. The benchmark suite includes 14 scientific andengineering application codes, covering everything from computational fluid dynamics (CFD) tomolecular modeling to image manipulation.Figure 8 shows that running E5-2697 v2 processors on the PowerEdge R720 provides a 38% upli
