    Default 1GB GDDR5 Radeon™ HD 7470M Graphics for gaming?

    What do you guys think about this card? The 7000 series for laptops are fairly new from what I've heard, and there are no gaming benchmarks on it yet.
    Also, how would a 5400 RPM drive work for gaming? The laptop I want has a 750GB 5400 RPM drive, I would rather it be more like 350-400GB and have it be 7200 RPM.

    See here: AMD Radeon HD 7470M - Notebookcheck.net Tech
    And here: AMD Radeon HD 6490M - Notebookcheck.net Tech
    Looks to be a re-badged 6490m DDR5

    Hard-drives have little impact on game performance, only affects loading times.

    Good luck

    I see! Thank you very much for clearing this up, I was extremely confused as there was very little discussion in regards to the 7470m.

    Is there really nothing new that the 7xxx series introduce? I've heard about there new "architecture" with nm chips or something like that. I'm not getting the real picture of that.

    I think it's just a die shrink from 40 nm to 22 nm; uses less wattage and produces less heat. Other than that, I don;t think there are any huge performance differences; maybe others can chime in

    Actually, I think the "less wattage and produces less heat" part is a biggie for me. This is will be obviously be good for laptops so that they can be a little cooler.

    But then again...90C temps would be the new 110C overheating error temps due to their size.

    Depends on which 7XXX it is. Some of them are 28nm, I don't think any of those have been released yet. The ones that are out now are just rebadged 6XXXs, still 40nm.

    DX11.1, New architecture, 28nm, less watts, better power to watt ratio, The desktop cards are also capable of being near enough fully switched off when not in used, down to about 2.6watts low enough for the fan to turn off. All bodes well for the laptop variants if their built on the same newer processes.
