AFAIK, hardware is usually done in a such way that pretty much everything is proportional to the master frequency. That said, less pixels should mean that it takes less clocks to get the job done. Also, r300s state management is not currently very "efficient" as can be seen from oprofiled reports... :) -- Aapo Tahkola ------------------------------------------------------- This SF.Net email is sponsored by the 'Do More With Dual!' webinar happening July 14 at 8am PDT/11am EDT.
