Compare any two graphics cards:
GeForce GTX 650 Ti vs Radeon HD 7790
IntroThe GeForce GTX 650 Ti uses a 28 nm design. nVidia has clocked the core frequency at 928 MHz. The GDDR5 memory works at a speed of 1350 MHz on this model. It features 768 SPUs along with 64 TAUs and 16 Rasterization Operator Units.
Compare those specs to the Radeon HD 7790, which uses a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 memory works at a frequency of 1500 MHz on this specific model. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 7790 should be 11% faster than the GeForce GTX 650 Ti in general, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 650 Ti is a bit (more or less 6%) more effective at texture filtering than the Radeon HD 7790. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 7790 is superior to the GeForce GTX 650 Ti, 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the 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 are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the 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 amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
