Compare any two graphics cards:
GeForce GTX 650 Ti 2GB vs Radeon HD 7770
IntroThe GeForce GTX 650 Ti 2GB makes use of a 28 nm design. nVidia has set the core speed at 928 MHz. The GDDR5 memory is set to run at a frequency of 1350 MHz on this particular card. It features 768 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 7770, which uses a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this model. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 650 Ti 2GB should in theory be a little bit faster than the Radeon HD 7770 in general. (explain)
Texel RateThe GeForce GTX 650 Ti 2GB should be quite a bit (about 48%) faster with regards to texture filtering than the Radeon HD 7770. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 7770 is the winner, not by a very large margin though. (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 max amount of information (measured in MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
