Radeon HD 7990 And GeForce GTX 690: Bring Out The Big Guns

Noise Comparison Videos: 500 FPS

Coil Squealing at 500 FPS

We commonly get complaints from readers about coil whine from graphics cards in older games or game menus, where very high frame rates are common. We're not strangers to this phenomenon, so we tested each graphics card at 500 FPS using an Unigine Sanctuary loop.

Every single card, including EVGA's GeForce GTX 690, demonstrates at least some squealing at these frame rates. It's barely noticeable from the dual-GK104 board, and the HIS 7970 X2 isn't too disturbing. But again, PowerColor's Devil13 HD7990 is barely tolerable.

    IMHO, the GTX690 looks best. There is something really alluring about shiny white metallic shine and the fine metal mesh. Along with the fluorescent green branding.
    Maybe i am too much of a retro SF buff :)

    What's the most impressive is that the GTX 690 was made by nVidia themselves and not an OEM. Very nice and balanced card.

    You can't really go wrong either way with these generally insane(so to speak) cards.

  • thanks for the in depth analysis with adaptive V-sync and radeon pro helping with micro stutter.

    not to take away anything for the hard work performed; i would have liked have seen nvidia's latest beta driver, 310.33, included also to see if nvidia is doing anything to improve the performance of their card instead of just adding 3d vision, AO, and sli profiles.

    AMD's Dual GPU at 500+ Watts of electricity is out for me.. Too Much Power and Noise..

    2 670's in sli is better than spending on a 690 and 2 7950's in Xfire is better than spending on a 7990. this way you save nearly $300 both ways
