GeForce GTX 580 3GB vs Geforce GTX 680


Intro

The GeForce GTX 580 3GB has a GPU clock speed of 772 MHz, and the 3072 MB of GDDR5 RAM is set to run at 1002 MHz through a 384-bit bus. It also is comprised of 512 SPUs, 64 TAUs, and 48 Raster Operation Units.

Compare those specifications to the Geforce GTX 680, which features a GPU core clock speed of 1006 MHz, and 2048 MB of GDDR5 memory set to run at 1502 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 128 TAUs, and 32 Raster Operation Units.

Geforce GTX 680 192256 MB/sec
Difference: 128 (0%)

Texel Rate

The Geforce GTX 680 should be quite a bit (more or less 161%) better at texture filtering than the GeForce GTX 580 3GB. (explain)

Geforce GTX 680 128768 Mtexels/sec
GeForce GTX 580 3GB 49408 Mtexels/sec
Difference: 79360 (161%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 580 3GB is superior to the Geforce GTX 680, but only just. (explain)

GeForce GTX 580 3GB 37056 Mpixels/sec
Geforce GTX 680 32192 Mpixels/sec
Difference: 4864 (15%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.

I still love my GTX 680 4GB, I have no trouble playing any games with it, and honestly as long as I have my 60 fps i'd good.
