Compare any two graphics cards:
GeForce GTX 580 3GB vs Geforce GTX 770
IntroThe GeForce GTX 580 3GB features a GPU clock speed of 772 MHz, and the 3072 MB of GDDR5 RAM runs at 1002 MHz through a 384-bit bus. It also is made up of 512 SPUs, 64 Texture Address Units, and 48 Raster Operation Units.Compare those specifications to the Geforce GTX 770, which uses a 28 nm design. nVidia has set the core frequency at 1046 MHz. The GDDR5 RAM runs at a frequency of 1753 MHz on this particular model. It features 1536 SPUs along with 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Geforce GTX 770 should perform a bit faster than the GeForce GTX 580 3GB in general. (explain)
Texel RateThe Geforce GTX 770 should be a lot (approximately 171%) better at texture filtering than the GeForce GTX 580 3GB. (explain)
Pixel RateThe GeForce GTX 580 3GB is just a bit (approximately 11%) faster with regards to anti-aliasing than the Geforce GTX 770, and also able to handle higher screen resolutions while still performing well. (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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also 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 ability to get to the maximum fill rate.
