MSI GTX 580 Lightning Twin Frozr III
Features and Specifications
By now we’re very familiar with the GF110 (GTX 580) architecture, so we’ll go with a quick recap. With this generation chip, it’s still based on the Fermi architecture and is very similar to the GF100 (GTX 480) design, though there have been a few changes. The CUDA cores have been bumped up to 512 and Texture Units have also increased slightly from 60 to 64. Polymorph Engines have increased to 16, along with higher core and memory clock speeds. Given these modest increases and nearly identical architecture, we’re a bit surprised this card isn’t the GTX 485 or GTX 490, but Nvidia doesn’t often follow conventional wisdom when designing or naming their models. In any event, the GTX 580 is upon us, promising improved power efficiency and temperatures.
The diagram below shows the architecture of the GTX 580.
Below is a chart that shows the significant differences in the current GeForce GTX performance lineup as things stand from Nvidia:
The MSI GTX 580 Lightning Twin Frozr III, however, gets a factory overclock out of the box, bringing speeds of 832MHz Core and 1050MHz memory (1664MHz Shader).
Needless to say, this is a nice addition to the package, but with a custom heatsink and overvoltage abilities, this card has plenty more surprises in store. We’ll take a closer look at that shortly, so let’s move onto the package and accessories.
