Compare any two graphics cards:
GeForce GTX 590 vs Geforce GTX 770
IntroThe GeForce GTX 590 comes with a GPU clock speed of 607 MHz, and the 1536 MB of GDDR5 memory runs at 855 MHz through a 384-bit bus. It also is comprised of 512 SPUs, 64 Texture Address Units, and 48 ROPs.
Compare that to the Geforce GTX 770, which features GPU clock speed of 1046 MHz, and 2048 MB of GDDR5 RAM running at 1753 MHz through a 256-bit bus. It also is made up of 1536 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 590 should theoretically be quite a bit superior to the Geforce GTX 770 overall. (explain)
Texel RateThe Geforce GTX 770 is a lot (about 72%) more effective at texture filtering than the GeForce GTX 590. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 590 is a better choice, by far. (explain)
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: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
