There is no truth in advertising when it comes to mobile GPU's.
These rebrands, just like the last round (continued here) are at the behest of the OEM's. Pretty hard to shift new stock for the holiday season if it doesn't boast higher model numbers that the same stuff thats been available all year.
Yo Ho Ho, and a Merry Christmas to the uninitiated from Dell, HP, Acer, Toshiba....
The comment about mobile GPU's is so true, and funny.
I remember last year a friend of mine was bragging about his 5870M in his laptop and how well it ran games at 1080P, but how he didn't like his 5770.
Then he found out a 5870M's specs are nearly identical to a 5770.
