I've been using Mflop instead of Gflop. Go check out Apple's G4 page. To clarify earlier tech errors from myself and others: G4 dual 800= 11.8 Gflops. That's still 6-10 times more data crunching per second than ANY OTHER PROCESSOR (card) currently available outside of refridgerator-size models. G4 is 128 bit wide, not 64 bits. To the best of my knowledge, most other machines run 32 or 64 bits wide-yuck. Total Impact is making expansion chassis' with up to 10 4-processor cards running G4 500's. If each G4 is worth a theoretical 5.3 Gflops than the Array would be around 212Gflops! The Linux core they use to run it all can handle more processors than that too!
