The Mac Pro is in the Unix workstation market. Although the high-end technical market has not traditionally been an area of strength for Apple, the company has been positioning itself as a leader in non-linear digital editing for high-definition video, which demands storage and memory far in excess of a general desktop machine. Additionally, the codecs used in these applications are generally processor intensive and highly threadable, which Apple's ProRes white paper describes as scaling almost linearly with additional processor cores. Apple's previous machine aimed at this market, the Power Mac G5, has up to two dual-core processors (marketed as "Quad-Core"), but lacks the storage expansion capabilities of the newer design.
