Compare any two graphics cards:
GeForce GTX 260 Core 216 vs Radeon HD 6790
IntroThe GeForce GTX 260 Core 216 comes with a core clock speed of 576 MHz and a GDDR3 memory speed of 999 MHz. It also uses a 448-bit memory bus, and makes use of a 65 nm design. It features 216 SPUs, 72 Texture Address Units, and 28 Raster Operation Units.Compare all of that to the Radeon HD 6790, which makes use of a 40 nm design. AMD has clocked the core frequency at 840 MHz. The GDDR5 memory is set to run at a frequency of 1050 MHz on this particular card. It features 800 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6790 should perform a bit faster than the GeForce GTX 260 Core 216 in general. (explain)
Texel RateThe GeForce GTX 260 Core 216 will be much (approximately 23%) faster with regards to AF than the Radeon HD 6790. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 260 Core 216 is the winner, but 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
