Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs Radeon HD 5830
IntroThe GeForce GT 240 GDDR5 1GB features a GPU core clock speed of 550 MHz, and the 1024 MB of GDDR5 RAM is set to run at 850 MHz through a 128-bit bus. It also features 96 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 5830, which uses a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this card. It features 1120(224x5) SPUs as well as 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5830 should in theory perform a lot faster than the GeForce GT 240 GDDR5 1GB overall. (explain)
Texel RateThe Radeon HD 5830 will be quite a bit (about 155%) more effective at texture filtering than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateThe Radeon HD 5830 will be a lot (about 191%) faster with regards to full screen anti-aliasing than the GeForce GT 240 GDDR5 1GB, and also should be able to handle higher screen resolutions without slowing down too much. (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 maximum amount of information (in units of MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write 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 core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
