Please... this topic has been beaten to death on the lists during the last
couple of weeks.
Briefly: If it's just about putting pixels on the screen, then what we win
with the faster rendering speed is lost due to the smaller bus bandwith to
the GPU. Plus, SD transfers go the same path, hence sharing bandwith with
transferring pixel commands to the GPU.
Number crunching though is almost twice as fast on the 02.
Can we talk about something else now?
