Technical specifications

  • CPU: SH-4 RISC|RISC CPU with 128 Bit FPU functions for 3D graphics computations (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 3-5 Mil polygons/second. Tile rendering eliminates overdraw by only drawing visible polygons. This allows more efficient use of polygons and can make games appear to have 2-4 times their actual polygon count (depending on amount of overdraw eliminated).
  • Memory: Main RAM: 16 MB 64 Bit 100 MHz, Video RAM: 8 MB 4x16 Bit 100 Mhz, Sound RAM: 2 MB 16 Bit 66 MHz
  • Sound Engine: Yamaha AICA Sound Processor: 22.5MHz 32-Bit ARM7 RISC CPU core, 64 channel PCM/ADPCM sampler, 128 step DSP
  • GD-ROM Drive: 12x maximum speed (Constant Angular Velocity)
  • GD-ROM: Holds up to 1.2 GB of data. A normal CD-ROM holds 700 megabytes.
  • Inputs: USB-like "Maple Bus". Four ports support devices such as digital and analog controllers, steering wheels, joysticks, keyboards and mouses, and more.
  • Dimensions: 189 mm x 195 mm x 76 mm (7 7/16" x 7 11/16" x 3")
  • Weight: 1.9 kg (4.4 lb)
  • Color: Majority are white. Some late models from a sports package are black.
  • Modem: Removable; Original Asia/Japan model had a 33.6 kbit/s; models released after September 9 1999 had a 56 kbit/s modem
  • 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.
