[citation][nom]cangelini[/nom]Bottom line: both companies are in the wrong, and ATI calling it's Mobility Radeon HD 4850 by that name is all the impetus Nvidia needs to call it's FASTER mobile solution a GeForce GTX 260M or 280M, regardless of what architecture is under the hood.[/citation]
While I understand you were responding to someone being overzealous, on thinking about this more I actually think ATI is being fairly honest. Because the architecture is the same as the desktop 4850, and they preface it as the "mobility" model...I'm not sure what else they should do.
Think in the reverse scenario: Several vendors offer overclocked versions of the 4850, GTX-260, et al...but they keep the same number. The number only changes with architecture no matter the overclocking, it's something else in the name that changes, such as adding "TOP" or "OC" or...whatever. We aren't going to see Sapphire's 1000MHz 4890 rebadged as a 4970 or something like that purely on the basis of an overclock, why should it be any different in the reverse scenario? Call it a 4730 even though it has more shaders than a 4830? How much sense does that make?
But, it is good to scrutinize everyone. AMD, Intel, NVidia, ATI...they've all done their little bits to market in ways that can be downright deceptive to consumers. NVidia just happens to be quite a bit more wrong in this circumstance.
