For something that carries an ARM720 or ARM920 core, I think a Geforce2Go or the ATI equivalent would be overkill. The ARM720 core is intended to be run at about 50MHz and will use 32MB SDRAM chips. The MCU is EP7312 by Cirrus (this is not confirmed). Does anyone know of a lesser and cheaper 3d chip in production?? Possibly directly connected to the RAM (DMA?) rather than using the PCI bus?
Thanks
