Percent faster than the previous model
The Power Mac G5 Quad encoded an HDV project 22 percent faster than the dual 2.7GHz Power
Mac G5. Performance gains were even better for SD and DV encoding: The Power Mac G5 Quad
encoded SD video 60 percent faster than the dual 2.7GHz Power Mac G5—and encoded DV
projects 44 percent faster.*
