GeForce GTX 580 3GB vs Geforce GTX 780
Intro
The GeForce GTX 580 3GB comes with a core clock frequency of 772 MHz and a GDDR5 memory speed of 1002 MHz. It also uses a 384-bit bus, and uses a 40 nm design. It is comprised of 512 SPUs, 64 TAUs, and 48 Raster Operation Units.Compare all of that to the Geforce GTX 780, which makes use of a 28 nm design. nVidia has clocked the core speed at 863 MHz. The GDDR5 RAM works at a speed of 1502 MHz on this particular card. It features 2304 SPUs along with 192 TAUs and 48 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.

Comments
One Response to “GeForce GTX 580 3GB vs Geforce GTX 780”I have two cards at the moment, both are dual gpu GTX 580. So I have four 580s technically. How would I compare that setup versus a single 780? Do I just multiply all the values for the 580 by four?
