The Dreamcast's specs:
The CPU is a Hitachi SH-4 that runs at 200 MHz. It reportedly runs four times faster than an Intel Pentium II chip for processing 3-D graphics.
The Graphics chip is the PowerVR provided by NEC. I could mention that the chip can provide such advanced features as texture mapping, ground shading, and the ability to render three million polygons per second. However all that adds up to is the fact that the graphics rival those of true arcade machines.
The audio is provided by Yamaha using a 32-bit ARM 7 RISC CPU with a processor capable of producing 64 channels of sound and full 3-D audio support. The sound is nothing short of amazing.
The Dreamcast boasts 26 MB of RAM divided into several parts. 16 MB in main RAM, 8 MB Video RAM and 2 MB of audio RAM.
The drive provided in the Dreamcast is a 12X speed GD-ROM drive.
The modem is a 56k winmodem utilizing the v.90 standard. The modem plugs into a serial port in the back of the unit. The modem will be able to be upgraded in the future to meet the changing standards.
The previously mentioned serial port is important as it provides the Dreamcast with expandability.
