Really, this gets no replies? The highest performing, single chip, mobile GPUs launch and no one replies?
It should be noted that these MR4000s are nearly identical to their desktop counter parts in terms of specs and features. THe MR4870, for example, still has 800 stream processors and GDDR5 RAM. Its clocks are lower, but that is to be expected in a mobile part.
I really hope to see some good Sager models with these chips. My old MR 9000 and 9600 were excellent in their day and it'd be nice to see ATI regain the mobile crown they once held for so many years.
