The game data is read from the GD-ROM at bootup, stored onto the SDR RAM to which the NAOMI reads from during game.

This system uses standard PC SDR-DIMM modules which are battery backed-up for storing game data. The NAOMI was extended in November 2000 so that it could interface with GD-ROM-based arcade games. large game cartridges) with up to 168В MB of usable data (more expensive but with faster loading), while the Dreamcast uses GD-ROM optical-storage with up to 1GB of storage (at the expense of load times). ДЄnother key difference between NAOMI and Dreamcast lies in the game-media - the NAOMI primarily uses ROM PC (printed circuit) boards (i.e. According to VideoLogic's president and CEO, Hossein Yassaie, in September 1998: ' With Dreamcast, PowerVR set out to create a new standard in 3D graphics for console gaming now with SegaвЂ™s Naomi, we will deliver unprecedented levels of 3D performance to arcade systems'. Multiple NAOMI boards can also be 'stacked' together to achieve better graphics performance, or for a multi-monitor setup.ДЄfter The House of the Dead 2, a newer revision of the PowerVR2 graphics chip was used in subsequent NAOMI systems. While the CPU of the NAOMI and Dreamcast operate at the same clock frequency, the NAOMI packs twice as much system and graphics memory, four times as much sound memory, a faster PowerVR2 graphics processor, faster VRAM bandwidth, and FPGA with additional processing. The NAOMI shares the same basic system architecture as the Dreamcast, with both systems using the same Hitachi SH-4 CPU and Yamaha AICA based sound system, along with different revisions of the PowerVR Series 2 GPU architecture.
