The main [[microprocessor]] is a [[R3000]] CPU made by [[LSI Logic]] operating at a [[clock rate]] of 33.8688&nbsp;[[MHz]] and 30&nbsp;[[Million instructions per second|MIPS]].{{sfn|McDonnell|1995}}{{sfn|Harris|1994|p=70}} This [[32-bit]] CPU relies heavily on the "cop2" 3D and matrix math coprocessor on the same die to provide the necessary speed to [[rendering (computer graphics)|render]] complex 3D graphics.<ref name=ignhistory/> The role of the separate GPU chip is to draw 2D polygons and apply shading and textures to them: the rasterisation stage of the graphics pipeline. Sony's custom 16-[[Audio bit depth|bit]] [[sound chip]] supports [[ADPCM]] sources with up to 24 sound channels and offers a [[sampling rate]] of up to 44.1&nbsp;[[Kilohertz|kHz]] and [[MIDI]] sequencing. It features 2&nbsp;[[Megabyte|MB]] of main [[Random access memory|RAM]], with an additional 1&nbsp;MB of [[video RAM]].{{sfn|Perry|1995|p=51}}{{sfn|Leigh|2018|p=189}} The PlayStation has a maximum [[List of color palettes|colour depth]] of 16.7&nbsp;million [[24-bit color|true colours]]<ref name="Ziff Davis">{{cite magazine |title=PlayStation Vs. Saturn: Battle of the Polygon Monsters |magazine=[[Electronic Gaming Monthly]] |issue=67 |publisher=[[Ziff Davis]] |location=Chicago |date=February 1995 |pages=94–95}}</ref> with 32 levels of transparency and unlimited [[colour look-up table]]s. The PlayStation can output [[Composite video|composite]], [[S-Video]] or [[Component video#RGB analog component video|RGB]] video signals through its AV Multi connector (with older models also having [[RCA connectors]] for composite), displaying [[display resolution|resolutions]] from 256×224 to 640×480 [[pixel]]s.{{sfn|Harris|1994|p=70}} Different games can use different resolutions. Earlier models also had proprietary [[Parallel port|parallel]] and [[serial ports]] that could be used to connect accessories or multiple consoles together; these were later removed due to a lack of usage.

The PlayStation uses a [[Proprietary software|proprietary]] video compression unit, MDEC, which is integrated into the CPU and allows for the presentation of [[full motion video]] at a higher quality than other consoles of its generation.{{sfn|Anderson|1997|p=56}} Unusual for the time, the PlayStation lacks a dedicated 2D graphics processor; 2D elements are instead calculated as polygons by the Geometry Transfer Engine (GTE) so that they can be processed and displayed on screen by the GPU.{{sfn|Boyer|1998|p=48}} While running, the GPU can also generate a total of 4,000 [[sprite (computer graphics)|sprites]] and 180,000 [[Polygon (computer graphics)|polygons]] per second, in addition to 360,000 per second [[Flat shading|flat-shaded]].{{sfn|Harris|1994|p=70}}{{sfn|Stockdale|1995|p=42}}
