NEC began selling the Express 5800/56Wb high-performance workstation in March 1999. The 56Wb was equipped with either one or two of Intel’s newest and fastest processor, the Pentium III Xeon processor (500/550 MHz). The processor’s excellent core performance — coupled with its use of 70 streaming SIMD extended instructions for faster multimedia processing and the high-speed multiprocessing computation capability — made the 56Wb ideal for 3D graphics, image editing, analytic simulations, and other processing-intense applications. Memory could be extended to as much as 2 GB thanks to the use of the 440GX AGPset chipset and 512 MB of ECC SDRAM memory. The 56Wb model with NEC’s TE3A 3D graphics accelerator chip scored a remarkable 156.30 on the Viewperf CDRS-04 test, a standard benchmark test for 3D rendering performance.
Although a workstation, this model is included in the PC server section because the Express 5800 series included both PC servers and PC workstations.
