Performance Results

These results show the relative speed increase provided by the PowerPC 601-based Workgroup Server 9150 over the Motorola 68K-based Workgroup Server 80. Figures include relative speed ratings for both applications and benchmark tests. The BYTE benchmark integer index figure is the geometric mean of the following tests: numeric sort, string sort, bit-field operations, floating-point emulation, assignment algorithm, IDEA (International Data Encryption Algorithm), and Huffman compression. The floating-point index figure is the geometric mean of the Fourier coefficients calculation, neural network simulation, and LUD (lower and upper decomposition). The tests were compiled using Metrowerks Code Warrior CW4.

The BYTE tests are beta versions, and the results are therefore preliminary. If BYTE finds a significant change between these results and those obtained when the benchmarks are in their final form, the magazine will publish an update.
