GeForce GTX 580 3GB vs Geforce GTX 680

Intro

The GeForce GTX 580 3GB features a clock speed 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 ROPs.

Compare those specifications to the Geforce GTX 680, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1006 MHz. The GDDR5 RAM is set to run at a speed of 1502 MHz on this model. It features 1536 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach 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.

I still love my ZOTAC GTX 580 3GB. I still playing any game with my 8GB RAM DDR2 1066MHz, and Intel Xeon quad core E5472 with 12 MB cache L2 and 3GHz 1600FSB.
