*Four 128-bit 54&nbsp;MHz or 108&nbsp;MHz Nuon MPE (Media Processing Element) [[very long instruction word]] processors supporting [[parallel computing|parallel operations]] on (at most) 32-bit scalars. An MPE's register file contains eight 128-bit [[processor register|registers]], which can be used to store vectors of that size (composed of 4 scalars), or be partitioned down to offer thirty-two 32-bit (scalar) registers, or eight packets of 3 (pixel) or 4 ("small") 16-bit vectors. Each MPE operates on [[random access memory|RAM]] that is local to itself, but MPEs 1 and 4 can directly operate on data located in system memory. Those same specific MPEs can use their memories as configurable caches, and have access to additional tag RAM for that purpose. MPEs have a hardware multiply unit, but no hardware division. There is no hardware support for floating point computation.<ref>[https://cdn.arstechnica.net/wp-content/uploads/2015/06/1383659488_NUON-Architecture-26-OEM.pdf] "NUON Multi-Media Architecture Aries 3 Specifications, Full OEM Version", September 26th, 2001</ref> Some report(s){{By whom|date=June 2023}} suggested that a certain model had sported a 333+&nbsp;MHz [[clock frequency]] but it was never released widely.
*[[MCS-251]] [[microcontroller]] for background task
*32 [[megabyte|MB]] 8-bit [[Fast Page Mode DRAM|Fast Page DRAM]] at 33&nbsp;[[MHz]], 512 [[kilobyte|KB]] sound RAM and 24 KB programmable [[read only memory|ROM]]
*2x 3d Media GL MPE with 8 MB 32-bit [[video RAM]] at 66 MHz.
*64~256&nbsp;MB writable ROM and optional hard drive (up to 137&nbsp;GB)   
*Optical drive support DVD or [[CD-R]]
