Sega NAOMI 2

Manufacturer: Sega

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, and stands as a beefed up version of the NAOMI specification. It is also fully backwards compatible with its predecessor.

The NAOMI 2 is by and large a more powerful successor of the NAOMI, adding a secondary CPU and rasterizer GPU at higher clock rates, adding a new powerful T&L GPU, and increasing the graphics memory. 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.
