Compare any two graphics cards:
GeForce 8800 GTX vs Radeon HD 4790
IntroThe GeForce 8800 GTX comes with core clock speeds of 575 MHz on the GPU, and 900 MHz on the 768 MB of GDDR3 memory. It features 128 SPUs as well as 64 TAUs and 24 Rasterization Operator Units.Compare those specifications to the Radeon HD 4790, which uses a 55 nm design. AMD has set the core speed at 600 MHz. The GDDR5 RAM works at a speed of 800 MHz on this particular card. It features 640(128x5) SPUs as well as 32 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the Radeon HD 4790 should be a bit faster than the GeForce 8800 GTX in general. (explain)
Texel RateThe GeForce 8800 GTX is quite a bit (more or less 92%) faster with regards to AF than the Radeon HD 4790. (explain)
Pixel RateThe GeForce 8800 GTX will be quite a bit (about 44%) better at full screen anti-aliasing than the Radeon HD 4790, and will be capable of handling higher screen resolutions without losing too much performance. (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 maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
