NAOMI2.jpg
Sega NAOMI 2
Manufacturer: Sega
Variants: Sega NAOMI 2 GD-ROM, Sega NAOMI 2 Satellite Terminal
Add-ons: GD-ROM
Release Date RRP Code

The Sega NAOMI 2 is an arcade board developed by Sega and is a successor to Sega NAOMI hardware. It was originally released in 2000. Since it uses similar NAOMI architecture (but significantly beefed up), it is also fully backwards compatible with its predecessor.

The NAOMI 2 is significantly more powerful than the NAOMI, including a dual CPU setup, new T&L GPU, dual rasterizer GPU, increased memory, and faster clock rates and bandwidth. This leads to games with much more polygons than a NAOMI game, rendered at much faster speeds, while the new T&L GPU adds advanced lighting and particle effects. It was also more affordable than the very expensive Sega Hikaru arcade system that preceded it.

As with the NAOMI, the NAOMI 2 was also available in GD-ROM and Satellite Terminal variants.

Development

VideoLogic's Elan, the T&L geometry GPU coprocessor used in the NAOMI 2, had been in development since 1998, when the original NAOMI arcade system and Dreamcast console launched. [1]

NAOMI 2 GD-ROM Specifications

The NAOMI GD-ROM, released in 2001, is identical to the standard NAOMI, but uses GD-ROM discs for storage instead of ROM cartridges. It comes with a DIMM Board, which is very similar to a ROM cartridge, but with RAM instead of ROM. When a game is installed, the GD ROM content is loaded onto the DIMM Board RAM, so that the game data runs from the DIMM Board rather than the GD-ROM disc. The NAOMI 2 GD-ROM specification includes the following differences:

  • Board composition: Motherboard + Daughter Board + DIMM Board
  • Storage media: GD-ROM drive
    • GD-ROM transfer rate: 1.8 MB/sec (1800 KB/sec)

Memory

  • RAM: 392–648 MB (SDRAM)
    • Main RAM: 32 MB
    • VRAM: 96 MB
    • Sound RAM: 8 MB
    • DIMM RAM: 256–512 MB [26]
  • L2 cache: 256 KB
  • ROM: 26 MB
    • System ROM: 2048.25 KB (24 MB BIOS EPROM, 256 bytes EEPROM)
    • DIMM ROM: 24 MB (EPROM)

Bandwidth

  • RAM bandwidth: 16–17 GB/sec
    • Main RAM: 1.6 GB/sec
    • VRAM: 13 GB/sec
    • Sound RAM: 132 MB/sec
    • SRAM: 44 MB/sec
