Compare any two graphics cards:
GeForce GTX 750 Ti vs Radeon HD 4790
IntroThe GeForce GTX 750 Ti has a clock frequency of 1020 MHz and a GDDR5 memory frequency of 1350 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.Compare all of that to the Radeon HD 4790, which features a core clock speed of 600 MHz and a GDDR5 memory frequency of 800 MHz. It also makes use of a 256-bit bus, and makes use of a 55 nm design. It features 640(128x5) SPUs, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon HD 4790 should theoretically be a little bit superior to the GeForce GTX 750 Ti in general. (explain)
Texel RateThe GeForce GTX 750 Ti will be a lot (about 113%) faster with regards to texture filtering than the Radeon HD 4790. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 750 Ti is the winner, 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 max amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
