GeForce GTX 980 vs Geforce GTX 680

Intro

The GeForce GTX 980 uses a 28 nm design. nVidia has set the core speed at 1126 MHz. The GDDR5 memory works at a frequency of 1750 MHz on this particular card. It features 2048 SPUs along with 128 Texture Address Units and 64 ROPs.

Compare those specifications to the Geforce GTX 680, which features a GPU core clock speed of 1006 MHz, and 2048 MB of GDDR5 RAM set to run at 1502 MHz through a 256-bit bus. It also is made up of 1536 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
