    Default Radeon 7670m vs GeForce GT640m 2GB on Maya

    I am planning to purchase an ultrabook that is powerful, and they come in these dedicated graphic cards. I have no idea how they will perform on Autodesk Maya 2013, can someone tell me how they will perform?

    I generally animate models and use them in animating scenes, then leave them to render overnight.

    Please try not to say, "how the hell do you expect to do this high production stuff on a 13" or 14" screen" or "you have better options (unless the option is available on an ultrabook)", I've heard it already.

    Thanks if you can offer any help!

    640M is faster than the 7670M.

    I think the HD 7670m is a rebranded HD 6750, so i would recommend going for the newer GT 640m.

    Hmm, never seen AMD rebrand old GPUs with higher product numbers before.

    No it's not. 6650M has DDR3, 7670M has DDR5.

    no it doesn't. at least in SONY's SVZ13's case, it's DDR3.

    Oh right. Urgh I wish all versions of a GPU just stuck with just one memory type. It'd be so much simpler for us customers :/

    Why make it support both? You've essentially got two cards there. Why market it as the same?

    I have the same peeve with NVIDIA. Half the 635, 640 & 650M's having GDDR5 and half having DDR3.

    The 7670M is just a rebranded 6750M and comes in GDDR3 and GDDR5 flavors. Obviously, the GDDR5 is faster.

    The Nvidia GT 640M is actually based on the new Kepler architecture. The GDDR5 version is a very decent performer and can run Battlefield 3 on Ultra settings at 1366x768 with 30 FPS. If you're gonna be doing Maya work, I would stick with Nvidia anyway because they have better support for compute technologies such as CUDA, PhysX, etc.
