Power And Battery Life

AMD's Mobility Radeon HD 6970 In CrossFire On Eurocom's Panther
By

Because the Eurocom Panther 2’s hard drive requires power to remain “active” while not transferring data, the GeForce GTX 470M and GTX 480M appear to have similar idle power. The Radeon HD 6970M consumes around 10 W more in 2D mode, though this may be improved later with new drivers and/or firmware.

Kick the system up to 3D mode and the single Radeon HD 6970M is in a dead heat with the GeForce GTX 470M. Nvidia's GTX 480M can’t even compete for thermal efficiency, converting an extra 40 to 50 watts per card into heat.

Problems getting the Radeon HD 6970M to idle down effectively with current drivers and Clevo’s initial firmware are reflected in reduced run time. These desktop replacement notebooks are designed to run primarily from a wall outlet anyway, but we like having the capacity to at least check our email a few times while en route to the next power source.

    Impressive gaming performance, power draw and price.

    Just goes to show AMD is more than just a big hitter in the CPU ring. Well done.

    So here we go again... using CPU tests for GPU articles...

    You know programs like photoshop, 3dStudio Max etc can really benefit from a good GPU, but definitely not on that tests you are running here.
    At 3d studio final renders are a CPU job and the GPU doesn't get involved in that at all, but if we have a heavy populated scene and we try to move around the camera or an object with openGL/Direct3D preview on all 4 views, THEN a good GPU can make the difference and this is where we can see as well the benefits of pro cards vs the gaming ones.

    So please, use the software and the hardware in a better way so we can get a better picture of the performance, people doesn't just play games, we are interested to see the actual benefits from a GPU while we work as well.
