Compare any two graphics cards:
GeForce GTX 460 2GB vs Radeon HD 5830
IntroThe GeForce GTX 460 2GB features a GPU core speed of 675 MHz, and the 2048 MB of GDDR5 memory runs at 900 MHz through a 256-bit bus. It also is made up of 336 Stream Processors, 56 Texture Address Units, and 32 Raster Operation Units.Compare that to the Radeon HD 5830, which features a clock speed of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It is made up of 1120(224x5) SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 5830 should be a little bit faster than the GeForce GTX 460 2GB overall. (explain)
Texel RateThe Radeon HD 5830 will be a bit (approximately 19%) faster with regards to texture filtering than the GeForce GTX 460 2GB. (explain)
Pixel RateThe GeForce GTX 460 2GB will be a lot (approximately 69%) faster with regards to FSAA than the Radeon HD 5830, and also 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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, 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 amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
