A little more information about what is used.
Some details have emerged about the technical specifications of the hardware for the Nintendo 3DS.
An anonymous source has told IGN that "two 266MHz ARM11 CPUs, along with a 133MHz GPU, 4MBs of dedicated VRAM, 64MBs of RAM, and 1.5GBs of flash storage" are powering the handheld.
The ARM11 processor is currently used in devices such as various smartphones, the Zune HD, and the Amazon Kindle. Previous reports have named the GPU as DMP's PICA200, with impressive video demonstrations but the performance would depend on the specific chip in use.
For comparison, the DSi has 133MHz ARM9 and 33 MHz ARM7 CPUs, 16MB of RAM, and 256 MB of flash memory.
