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. It was more affordable than the Sega Hikaru arcade system that preceded it.
The NAOMI 2 is by and large a more powerful successor of the NAOMI, adding a secondary CPU and GPU at higher clock rates, adding a new T&L GPU, and increasing the main 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.
As with the NAOMI, the NAOMI 2 was also available in GD-ROM and Satellite Terminal variants.
