Compare any two graphics cards:

Geforce GTX 680 vs Geforce GTX 760

Intro

The Geforce GTX 680 features a GPU clock speed of 1006 MHz, and the 2048 MB of GDDR5 memory runs at 1502 MHz through a 256-bit bus. It also is comprised of 1536 SPUs, 128 TAUs, and 32 ROPs.

Compare those specs to the Geforce GTX 760, which comes with GPU core speed of 980 MHz, and 2048 MB of GDDR5 RAM set to run at 1502 MHz through a 256-bit bus. It also is made up of 1152 Stream Processors, 96 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 760		170 Watts
Geforce GTX 680		195 Watts
	Difference: 25 Watts (15%)

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The Geforce GTX 680 will be quite a bit (about 37%) better at AF than the Geforce GTX 760. (explain)

Geforce GTX 680		128768 Mtexels/sec
Geforce GTX 760		94080 Mtexels/sec
	Difference: 34688 (37%)

Pixel Rate

If using a high screen resolution is important to you, then the Geforce GTX 680 is the winner, though only just barely. (explain)

Geforce GTX 680		32192 Mpixels/sec
Geforce GTX 760		31360 Mpixels/sec
	Difference: 832 (3%)

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 transferred past the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 ability to get to the maximum fill rate.
