POWER8 (and No. 23) is King

with one comment

So it was just announced that LeBron James will be back wearing No. 23 for his return to the Cleveland Cavaliers next season. Cleveland, the old “mistake by the lake” and my current hometown, has had a pretty good last few weeks. With two major coups — a US political national convention and (against all odds) LeBron coming home, there couldn’t be a better place to be.

POWER8 systems have had an awesome month as well. As we know, on top of enterprise RAS and security, performance of POWER8 is king. Let’s take a look at the two latest leadership benchmark results that have been published in two key workloads — Java and virtualization.

  • SPECjbb2013 is THE Java server benchmark. It is based on a world-wide supermarket company with an IT infrastructure that handles a mix of point-of-sale requests, online purchases and data-mining operations. Two metrics are important – a pure throughput metric and a metric that measures critical throughput under service-level agreements (SLAs) specifying response times. So very real world. And the IBM Power S824 (POWER8) system achieved over 95% better performance per core than  Oracle SPARC and over 2x better than x86 Cisco UCS. (1)

 

  • The SPECvirt_sc2013 virtualization benchmark reflects the heavy volume and sudden peaks of traffic faced by datacenter servers used for virtualized server consolidation. It provides four workloads based on real-world traffic faced by a web server, a Java application server, an email server and a batch server. Again, here are the workloads we use every day.And the IBM Power S824 (POWER8) system achieved the #1 result per core and is over 2x the performance per core of the HP DL560 x86 system. (2)

 

So we are talking a winning technology with POWER8 — and a winning city (LeBron, please take us there!)
