IBM posts first SPECpower benchmark score of more than 3,000 overall
dx360 M3 demonstrates superior power efficiency with leadership performance per watt
March 16, 2010 ... IBM® today announces a leadership SPECpower® benchmark result for the IBM
System x® iDataPlex™ dx360 M3 server. Demonstrating exceptional performance per watt, the dx360
M3 server achieved a Performance to Power Ratio of 3,038 overall ssj_ops/watt on the
Using the new Intel® Xeon® Processor X5670 and a 900-watt high-efficiency power supply, the dx360
M3 has demonstrated that it can deliver outstanding performance and reduce energy consumption in
the data center. Compared to its previous leadership 2-processor score of 2,231, the dx360 M3's new
score represents a power-efficiency improvement of 36%. (1)
The dx360 M3 was configured with the Intel® Xeon® Processor X5670 (2.93GHz with 256KB L2 cache
per core and 12MB L3 cache per processor—2 chips/12 cores/6 cores per chip), 12GB of memory, one
50GB solid state drive, and IBM J9 Java 6 (using a 1500MB heap), and Microsoft® Windows® Server
2008 R2 Datacenter Edition. (2)
