The RISC System/6000(r) (RS/6000(tm)) 300 Series workstations and servers are powerful, industry-leading systems. They provide excellent price/performance for interactive 2D and 3D graphical applications, multi-user commercial applications, and numeric intensive computing capability.

Customer solutions

The RS/6000 300 Series desktop workstations and servers provide a broad range of performance and function for technical and commercial customers. Models range from the low-end POWER Model 370 server (62 MHz), to the POWER2 Models 380 (59 MHz), 390 (67 MHz), and 39H (67 MHz) servers. As high-end workstation performers, the POWER2-based 3AT, 3BT, and 3CT also offer 59 and 67 MHz clock rates.

For technical users, the 300 Series offers a broad range of support for graphics functions. The workstations are ideally suited for applications requiring sophisticated interactive 2D and 3D graphical simulations, such as CADAM(r) and CATIA(r).

The 300 Series processors, with their superscalar architecture, protect your investment and provide increased performance as your needs grow.

Technical users will appreciate the outstanding integer and floating-point performance available on the desktop for their compute-intensive

applications. In the commercial arena, the 67 MHz clock rate of Model 390 and 39H means high-speed online transaction processing.

The 300 Series also helps protect your investment by providing a range of performance upgrade options. All currently available models can be upgraded to the higher performing 3AT, 3BT, 3CT, 380, 390, and 39H models and to the SMP Model G30 PowerPC server.

Values shown here are the results of development-level systems. All performance data was obtained in a specific environment and is presented as is for illustrative purposes only. While these values should be indicative of generally-available systems, no warranties or guarantees are stated or implied by IBM. IBM recommends application-oriented testing for performance predictions and offers the above commonly reported benchmarks only as an initial indicator. Additional information on these tests are available from your IBM local Branch Office or IBM Authorized Reseller.

AIX 4.1.1 was used with each of the benchmarks. IBM C Set++ for AIX/6000 3.1 & AIX XL FORTRAN Version 3.2 are the compilers used in these tests. The preprocessors used in the tests include KAP 2.5 for FORTRAN and KAP/C 1.4 from Kuck & Associates, VAST-2 X.03h28 from Pacific-Sierra Research. The preprocessor products are purchased separately.

SPECint92: Geometric mean of six integer tests which comprise the CINT92 benchmark suite. All of these are written in C language. Baseline SPECint92 results are included in the detailed results.

SPECfp92: Geometric mean of 14 tests that represent the CFP92 benchmark suite. Five of the tests are single precision while the remaining nine are double precision. Two tests are written in C language and the rest are written in FORTRAN. Baseline SPECfp92 results are included in the detailed results.

Linpack DP: Double Precision, n=100 results with AIX XL FORTRAN compiler, with optimization. Units are megaflops (MFLOPS).

Linpack SP: Single Precision, n=100 results with AIX XL FORTRAN compiler, with optimization. Units are megaflops (MFLOPS).

Linpack TPP: Toward Peak Performance, n=1,000 results with AIX XL FORTRAN compiler, with optimization. Units are megaflops (MFLOPS).
