PRODUCT PICTORIAL & WALKTHROUGH
Let's take a virtual walk around Zotac's version of the GTX 570.
First off we start at this videocard's VPU. Zotac's use of the 40nm manufactured GF110 core is stock clocked at 732Mhz core, 950Mhz 320bit DDR5 memory which is bandwidth capable of 152.0 Gb/sec memory transfer. This coupled with the VPU's 480 unified shaders is capable of 29.3 GPixels/sec and 43.9 GTexels/s while drawing 300 watts during maximum load and 150 watts at idle.
Zotac chose to use the reference based GPU cooler that exhausts hot air directly out of the case. As with the HD 6970 I have reviewed earlier the exhaust was hot to say the least. After a FurMark stress test, the back exhaust plate was again too hot to touch. Although the cooler seems to be enough to keep temperatures down, testing under a full 1920x1200 FurMark stress test load on an open testbed had temperatures reaching 83c before they would stabilize and 35c during idle. The reference cooler would tend to get overwhelmed rather quickly and temperatures would rise rather quickly and would take a long time to come back down after the load was removed. This in my opinion is due to the fan profile just being too low. Allowing the videocard to control the fan speed, the fan rpm wouldn't go above 1800rpms. Although this allows the card to be quiet, it isn't helping the temperature control.
The back of the card is completely void of any obstruction to interfere with any sort of upper motherboard components and facilitated an easy install. Also keep in mind that this is a full size videocard and consideration should be taken if you are planning on installing this videocard on a smaller motherboard or case. Also note in the top right hand corner you have your SLI bridge connections for use on an Nvidia multi-videocard setup.
