Compare any two graphics cards:
VS

GeForce GTX 460 (OEM) vs Geforce GTX 690

Intro

The GeForce GTX 460 (OEM) comes with a core clock frequency of 650 MHz and a GDDR5 memory frequency of 850 MHz. It also uses a 256-bit memory bus, and uses a 40 nm design. It features 336 SPUs, 56 TAUs, and 32 ROPs.

Compare all that to the Geforce GTX 690, which has a core clock frequency of 915 MHz and a GDDR5 memory speed of 1502 MHz. It also features a 256-bit memory bus, and makes use of a 28 nm design. It is comprised of 1536 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

GeForce GTX 460 (OEM) 36400 Mtexels/sec
Difference: 197840 (544%)

Pixel Rate

The Geforce GTX 690 is quite a bit (about 182%) better at FSAA than the GeForce GTX 460 (OEM), and capable of handling higher screen resolutions better. (explain)

Geforce GTX 690 58560 Mpixels/sec
GeForce GTX 460 (OEM) 20800 Mpixels/sec
Difference: 37760 (182%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
