Geforce GTX 680 vs Geforce GTX 760

Intro

The Geforce GTX 680 has a core clock speed of 1006 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It is made up of 1536 SPUs, 128 TAUs, and 32 ROPs.

Compare those specs to the Geforce GTX 760, which comes with a core clock frequency of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also features a 256-bit bus, and makes use of a 28 nm design. It is made up of 1152 SPUs, 96 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines 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 fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
