[edit] Technical specifications
Internal view of a Dreamcast ConsoleProcessor
SH-4 RISC CPU with 32-bit Instruction Set and 128-bit FPU functions (operating frequency: 200 MHz, 360 MIPS, 1.4 GFLOPS)
Graphics Engine
PowerVR2
CLX2, 7.0 Mil polygons/second peak performance, supports Trilinear filtering. Actual maximum in game performance (with full textures, lighting, gameplay, etc.) of over 5 Mil polygons/second.
Tile Based Deferred Rendering eliminates overdraw by only drawing visible fragments. This makes required fillrate almost independent from scene depth complexity, thus making up for a low, compared to other 6th generation consoles, nominal fillrate of 100 MPixels/s as effective fillrate can be triple that amount.
Graphics hardware effects include gouraud shading, z-buffering, anti-aliasing and bump mapping.

PAL: No known alternate designs or colors
Networking
A black 56k Dreamcast modem.Modem: Removable; speed varied among regions:
Original Asia/Japan model had a 33.6 kbit/s; consoles sold after September 9, 1999 had a 56 kbit/s modem
All American models had a 56 kbit/s
All PAL models had a 33.6 kbit/s
Broadband: these adapters are available separately and replace the removable modem
HIT-400: "Broadband Adapter", the more common model, this used a Realtek 8139 chip and supported 10 and 100 Mbit speeds.
HIT-300: "Lan Adapter", this version used a Fujitsu MB86967 chip and supported only 10 Mbit speed.
