Compare any two graphics cards:
GeForce GTX 260 216SP 55 nm vs Radeon HD 7790
IntroThe GeForce GTX 260 216SP 55 nm makes use of a 55 nm design. nVidia has set the core frequency at 576 MHz. The GDDR3 memory is set to run at a frequency of 999 MHz on this specific model. It features 216 SPUs along with 72 Texture Address Units and 28 Rasterization Operator Units.Compare that to the Radeon HD 7790, which comes with core clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 1024 MB of GDDR5 RAM. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 260 216SP 55 nm should perform a little bit faster than the Radeon HD 7790 overall. (explain)
Texel RateThe Radeon HD 7790 should be quite a bit (about 35%) better at texture filtering than the GeForce GTX 260 216SP 55 nm. (explain)
Pixel RateThe GeForce GTX 260 216SP 55 nm is just a bit (more or less 1%) better at anti-aliasing than the Radeon HD 7790, 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: Bandwidth is the max amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the 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 maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
