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 frequency at 928 MHz. The GDDR5 RAM works at a frequency of 1350 MHz on this specific card. It features 768 SPUs along with 64 TAUs and 16 Rasterization Operator Units.Compare all of that to the Radeon HD 7770, which makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this particular card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 650 Ti 2GB should theoretically be just a bit faster than the Radeon HD 7770 overall. (explain)
Texel RateThe GeForce GTX 650 Ti 2GB is much (approximately 48%) more effective at texture filtering than the Radeon HD 7770. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 7770 is superior to the GeForce GTX 650 Ti 2GB, though not 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
