Dreamcast Hardware Specs
Hitachi 128 bit graphics engine with an on-board RISC processor SH4 (operating frequency of 200MHz 360 MIPS/1.4 GFLOPS). The SH4 is optimized for floating point calculations (key to 3D) and is four times faster than the Pentium II.
* Note: the Dreamcast will have both 64 bit and 128 bit components. Polygons:
More than 3 million polygons per second.
* Graphics Chip:
NEC PowerVR2 (rendering capacity: over 3 million polygons per second),
* which outperforms today's most advanced arcade systems. Hardware Graphic Effects:
Bump mapping, Triangular / Quad Engine, real-time lighting, fog, scaling, rotation, alpha-blending, trilinear filtering, super sampling anti-aliasing, texture filtering, perspective correction, ARGB gouraud shading, MIP-mapping: point, bilinear, trilinear, anisotropic environment mapping, specular effects.
* Sound Processor:
32-bit Yamaha Super Intelligent Sound Processor (simultaneously articulates 64 sounds), which is as powerful (alone) as some next generation consoles.
* Operating Systems:
Customized OS using Windows CE as its base (Supports Direct X) for
a flexible, versatile development environment supported by Microsoft Visual Studio
development System Version 5.0 and refined Visual C++. As a result, Dreamcast software
is compatible with PCs and can take full advantage of hardware features. The OS will be on every
* Dreamcast disc to allow for easy upgrades. Also, Sega will provide its own OS which will allow developers access to even more of the Dreamcast's vast powers. Arcade:
Will be compatible with the DC-based Naomi arcade board that Sega and Capcom will
* support. As of October 1998, there are over 20 arcade developers signed on to produce Naomi games. RAM:
16MByte (64Mbit SD-RAM x 2) main system, 8MB of VRAM and 2MB for Audio RAM. 26MB RAM total.
* CD-ROM Drive:
12-speed ( Maximum )
* CD Format:
Proprietary compact disc by Yamaha with 1GB storage (54% more storage than
* standard CDs) and they'll include the Operating System. Modem:
A built-in 33.6Kbps modem with full support for V34, V42 and MNP5. It can be upgraded
* with faster modems and cable modems. The US Dreamcast will likely use a 56k modem. Network:
Built in network play.
Red, Yellow, Blue, and Gray. Analog and digital directional control with anolog triggers.
* Four controller ports standard. The control ports have a peak transfer rate of 2MB/sec, allowing the creation of high-end peripherals, such as true force feedback. Visual Memory System (VMS) (sold separately): A liquid-crystal display PDA for game data
* backup and data exchange. It will be called the Visual Memory Unit (VMU) in America because of trademark rights. Console Dimensions:
7 7/16" X 7 11/16" X 3" , 190 mm (W) x 195 mm (H) x 78 mm (D)
4.4#, 2.0 kg
* Release Date:
November 20, 1998 (Japan), September 1999 (USA)
* Data storage:
Save game files are stored on the PDA (aka VMS)
* CPU 8-bit
