Compare any two graphics cards:
GeForce GTX 260 Core 216 vs Radeon HD 6790
IntroThe GeForce GTX 260 Core 216 comes with a GPU clock speed of 576 MHz, and the 896 MB of GDDR3 RAM runs at 999 MHz through a 448-bit bus. It also is made up of 216 SPUs, 72 Texture Address Units, and 28 Raster Operation Units.Compare those specs to the Radeon HD 6790, which has a GPU core clock speed of 840 MHz, and 1024 MB of GDDR5 memory running at 1050 MHz through a 256-bit bus. It also features 800 Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6790 should in theory be just a bit better than the GeForce GTX 260 Core 216 in general. (explain)
Texel RateThe GeForce GTX 260 Core 216 should be a lot (approximately 23%) better at anisotropic filtering than the Radeon HD 6790. (explain)
Pixel RateThe GeForce GTX 260 Core 216 will be a little bit (approximately 20%) more effective at full screen anti-aliasing than the Radeon HD 6790, and also will be able to handle higher resolutions better. (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 (in units of MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core clock 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 in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
