    Xotoic custom GPU with sager np9150. Can we ask for a 660m instead of a 670m?

    So the title says it all. I'm wondering if we can customize the build and request a 660m instead of the 670m for a np9150?

    Why would you want to?

    He wants 128bit GDDR5 apparently. The 28nm Kepler I suppose. I don't see why he doesn't just go the other direction and get the 7970M, with 256bit GDDR5, faster and with the 28nm GCN.

    And if you're going for 660M, might as well drop down to 650M then, since they are the same, just clocked differently.

    If I had to guess, it would be because the 660m is "newer" (28nm, Kepler, etc), runs cooler, and has about the same performance of the 670m.

    Yea the 660m is equal to the 670m (give or take 10-15%) and you can get to stock 670m by over clocking.

    I thought the 660m out preformed the 650m by a ton? One is the first GTX model line and the 650 is the end of the GT line.

    I'm looking to reduce the power pull to 150w compared to a max draw of 180w.

    I'm not sold on AMD GPUs or CPUs and have had bad experiences with them.

    We are not able to get the 660M in the NP9150. While he 670M does use the fermi architecture its is still 10-15% faster as mentioned. While you can OC the 660M to get to 670M speeds, you can still OC the 670M to go beyond that.

    Ok thanks for the answer. I was just checking to make sure. I was willing to take the performance hit for a reduction on power draw.

    Same reason I'm still looking at the 660m: decent performance, with reduced heat.

    I heard from one source that 660m does not run cooler and more energy efficient than 670m, because it runs at a higher clock to make up for the reduced memory bandwidth.

    Needs confirmation here.

    When overclocked the 670m is 35% faster than the 660m overclocked and at idle is switched off.

    I said heat when in load, not power consumption when idling.

    Malibal has the 660m available.

    Its not 35% cooler so your efficiency will actually go down so feel free to downgrade.
