Sega collaborated with Microsoft on the Dreamcast's development, and this partnership would continue later with the Xbox. Sammy's Atomiswave arcade board was also based on the Dreamcast and Naomi. Sega also released the Naomi, an arcade system board with similar components to the Dreamcast. The audio chip could generate 64 voices with PCM or ADPCM codec and provided ten times the performance of the Saturn's sound system. There is a 2 MB audio RAM, which complemented a powerful 67 MHz Yamaha AICA sound processor, with a 32-bit ARM7 RISC CPU core. It had a PowerVR2 GPU at 100 MHz, which theoretically was capable of pushing 3 million polygons/second on-screen. It had a Hitachi SH-4 RISC CPU at 200 MHz with 16 MB of RAM and 8 MB of VRAM.
