OUR DREAMCAST PAGE LAST UPDATED 02/08/03
The Sega Dreamcast's CPU is a customized Hitachi
SH4 RISC (Reduced Instruction Set Chip) which provides 128-bit performance and
runs at 200MHz. It has been modified by Sega and Hitachi to enhance its
floating-point operations capabilities which are important for high-output 3D
calculations. The SH4 processor can perform floating-point operations four times
faster than the Intel Pentium II chip. NEC and Videologic combined to develop the Power
VR which drives the Dreamcast's graphics engine. The Power VR boasts a peak
output of more than three million polygons per second and adds customized
anti-aliasing technology to the platform. High-resolution fog and water effects
and a more vivid appearance of light and shadow are among the refined graphics
that sets the Dreamcast system apart from other consoles. Yamaha is providing a dedicated 3D Super
Intelligent Sound Processor for the Dreamcast system. It is a chip is capable of
producing 64 channels of sound. Sega also teamed with Yamaha to develop a
customized 12x GD-ROM drive for Dreamcast. The new drive is intended to
dramatically minimize the standard loading time for a disc-based console. This
advantage will encourage the creation of more complex games and larger playing
fields. The Windows CE operating system that Microsoft specially developed for the Dreamcast has been optimized to run DirectX applications. The primary motive for creating this specialized software was to simplify the process of game developing for third party companies. Even with that, it couldn't stand up to the PS2 at the time. Now that Sega discontinued their home hardware division. This system is becoming quite a collectable.
