The Market

• Intel has a solid lead
• No competition
• AMD handicapped by declining CPU profits
• Possible depression

3
An Idea or a Fad?

Xi Yion a Single Instruction Multiple
Data (SIMD) happens four times as fast as on a
single instruction single data machine
5
mi (ai gt bi)?ai 2bi 3 Happens
without branch instructions on a cell. So four
values have already been assigned by the time a
single instruction single data has queued the
first branch.
