Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs Radeon HD 5750 1GB
IntroThe GeForce 8800 GTS (G80) 320MB has core speeds of 513 MHz on the GPU, and 792 MHz on the 320 MB of GDDR3 memory. It features 96 SPUs along with 48 TAUs and 20 ROPs.Compare those specs to the Radeon HD 5750 1GB, which makes use of a 40 nm design. AMD has set the core frequency at 700 MHz. The GDDR5 memory runs at a frequency of 1150 MHz on this card. It features 720(144x5) SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5750 1GB, in theory, should be a little bit faster than the GeForce 8800 GTS (G80) 320MB overall. (explain)
Texel RateThe Radeon HD 5750 1GB should be a little bit (more or less 2%) faster with regards to anisotropic filtering than the GeForce 8800 GTS (G80) 320MB. (explain)
Pixel RateThe Radeon HD 5750 1GB should be a little bit (more or less 9%) more effective at AA than the GeForce 8800 GTS (G80) 320MB, and should be capable of handling higher resolutions more effectively. (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 largest amount of information (counted in megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core 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 card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
