Main Ram : 32 megs
Main Memory : 32 MByte 
Graphic Memory : 16 MByte 
Sound Memory : 8 MByte 
Media : ROM Board (maximum size of 172MBytes) / GD-Rom
Simultaneous Number of Colors : Approx. 16,770,000 (24bits)

Additional Features : Bump Mapping, Fog, Alpha-Bending (transparency), Mip Mapping (polygon-texture auto switch),
Tri-Linear Filtering, Anti-Aliasing, Environment Mapping, and Specular Effect.
Known games on Naomi hardware : 64+ 
NAOMI (New Arcade Operation Machine Idea) also Japanese for beauty above all else.
Notice that Naomi has twice the amount of main memory and graphics memory that Dreamcast has, so ports from Naomi
to DC may involve more conversion time. Also note that the Naomi board has four times the sound memory of the Dreamcast,
and the reason for this is because the Naomi board is'nt meant to spool redbook audio from the GD-ROM drive.
The Naomi architecture is very flexible in that a cabinet can have anywhere from 1 to 16 boards. A multi board system 
would operate in parallel increasing the power of the system tremendously! Theoritically a 16 board Naomi system could do
(16 x 3.5 mpps) = 56 million polygons per second maximum! Realistically it would most likely be around 20 to 30 mpps.
Then of course there is also the issue of the CPU being capable of driving all of this hardware.
