Yeah, not sure where ED got those numbers from, but I did try to clear that up in a different thread a while back. The graphics core in all SOC's is a fractional value of the main processor clock. It would be impossible to keep the pipe full if the clock was anywhere near the processor clock and would completely dominate the memory bus. The result would be degraded performance at an ever higher power consumption! The graphics core does have a set clock speed that will be made available when Pandora is released.
The ARM core clock speed doesn't seem to have a pre-defined speed. TI seems to expect their customers to clock the chip at a speed that suits their needs for battery life but then we aren't using a tiny little battery like you would have in a cell phone (which is where these chips usually go) so we should have more freedom to speed it up as we see fit. Development kits are set at 440MHz and 550MHz and of course they have that news report at 1GHz. It will probably be a very dynamic setup for Pandora: low clock for things like the main menu, MP3 playback, and some video playback and then boost the clock for apps that need it (like emulators and web browsers).
With all this interesting and "free" MHz Skills of the Chipset, maybe it would be good to know, how fast the Pandora clocks. Because nobody liked my Idea of an seperate MHz Display, the current Clockspeed could be displayed optional in the applications or with an always working key-combination over all applications?
I always like to know the current speed of my computers.
