Compare any two graphics cards:
GeForce GTX 650 Ti vs Radeon HD 4770
IntroThe GeForce GTX 650 Ti uses a 28 nm design. nVidia has set the core frequency at 928 MHz. The GDDR5 memory works at a frequency of 1350 MHz on this model. It features 768 SPUs along with 64 Texture Address Units and 16 ROPs.Compare all that to the Radeon HD 4770, which uses a 40 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 RAM runs at a speed of 800 MHz on this particular card. It features 640(128x5) SPUs as well as 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 650 Ti, in theory, should perform quite a bit faster than the Radeon HD 4770 in general. (explain)
Texel RateThe GeForce GTX 650 Ti should be much (about 147%) faster with regards to anisotropic filtering than the Radeon HD 4770. (explain)
Pixel RateThe GeForce GTX 650 Ti is a lot (approximately 24%) better at anti-aliasing than the Radeon HD 4770, and will be able to handle higher 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: Bandwidth is the max amount of information (in units of MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of 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, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
