IBM Shatters Computing Price Performance Barrier With New High Performance POWER5+(TM) Server

IBM Intellistation™ POWER 185 Express is IBM's lowest priced AIX 5L workstation ever. It has advanced 3D graphics capabilities for a UNIX workstation with excellent performance. The IBM Intellistation POWER 185 Express is great for AIX 5L and Linux application development and more than meets IBM's Quiet Office standard for low-noise environments(11).

1. IBM TPC-C result of 1,025,169 tpmC at $4.42/tpmC on a 16-core (8 processors, 32 threads) 2.2 GHz IBM System p5 570 (configuration planned to be available 05/31/06)2. HP TPC-C result of 1,008,144 tpmC at $8.33/tpmC on a 64-core (64 processors, 64 threads) 1.5 GHz Superdome running HP/UX (configuration available 04/14/04)3. HP TPC-C result of 332,265 tpmC at $4.48/tpmC on a 16-core (16 processors, 16 threads) 1.6 GHz rx8620 running Windows Server 2003 Datacenter Edition (configuration available 07/15/05)4. IBM System p5 560Q (16-cores, 8 chips) SPECjbb2005 result of 226,291 bops, 28,286 bops/JVM compared with all published competitive 16-core system results.5. IBM System p5 575 8-core (2.2 GHz) Stream Triad standard result of 96,327 (tuned result of 100,523) vs. HP Integrity rx7620 8-core (1.5 GHz) Stream Triad standard result of 10,283. IBM System p5 575 16- core (1.9 GHz) Stream Triad standard result of 86,062 vs. HP Integrity Superdome 16-core (1.5 GHz) Stream Triad standard result of 21,053.6. IBM System p5 570 16-core (2.2 GHz) SPECjbb2005 result of 326,651 bops (40,831 bops/JVM) compared with all published competitive 16-core system SPECjbb2005 results and IBM System p5 570 8-core (2.2 GHz) SPECsfs97.v3 result of 169,786 compared with all published competitive 8-core system SPECsfs97.v3 results.7. SPECjbb2005 IBM System p5 510 (2-cores, 1 chip) 36,039 bops, 36,039 bops/JVM compared with all published competitive 2-core system results.8. Based on IBM rPerf comparative performance metrics, System p5 520Q 4-core 1.5 GHz rPerf result of 18.75, System p5 520 2-core 1.9 GHz rPerf result of 11.16 and eServer p5 520 2-core 1.65 GHz rPerf result of 9.86. rPerf (Relative Performance) is an estimate of commercial processing performance relative to other pSeries systems. It is derived from an IBM analytical model which uses characteristics from IBM internal workloads, TPC and SPEC benchmarks. The rPerf model is not intended to represent any specific public benchmark results and should not be reasonably used in that way. The model simulates some of the system operations such as CPU, cache and memory. However, the model does not simulate disk or network I/O operations. rPerf estimates are calculated based on systems with the latest levels of AIX 5L and other pertinent software at the time of system announcement. Actual performance will vary based on application and configuration specifics. The IBM ~ pSeries 640 is the baseline reference system and has a value of 1.0. Although rPerf may be used to approximate relative IBM UNIX commercial processing performance, actual system performance may vary and is dependent upon many factors including system hardware configuration and software design and configuration.9. IBM System p5 560Q (16-cores, 8 chips) SPECjbb2005 result of 226291 bops, 28286 bops/JVM compared with published SUN Fire V40z (4- cores, 4 chips) result of 37,034 bops, 37034 bops/JVM.10. IBM System p5 575 8-core (2.2 GHz) SPECfp_rate2000 result of 382.0, SPECint_rate2000 result of 200.0, SPECompM2001 (peak) result of 40,560 OpenMP performance11.
