Compare any two graphics cards:
GeForce GTX 970 vs Radeon HD 7790
IntroThe GeForce GTX 970 has a GPU clock speed of 1050 MHz, and the 4096 MB of GDDR5 memory is set to run at 1750 MHz through a 256-bit bus. It also is comprised of 1664 Stream Processors, 104 Texture Address Units, and 64 ROPs.Compare all of that to the Radeon HD 7790, which features a core clock frequency of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 970, in theory, should be quite a bit faster than the Radeon HD 7790 overall. (explain)
Texel RateThe GeForce GTX 970 is much (more or less 95%) faster with regards to AF than the Radeon HD 7790. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 970 is the winner, and very much so. (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 transported over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
