Compare any two graphics cards:
GeForce GT 340 vs Radeon HD 5830
IntroThe GeForce GT 340 comes with core speeds of 550 MHz on the GPU, and 850 MHz on the 512 MB of GDDR5 RAM. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.Compare that to the Radeon HD 5830, which makes use of a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this specific card. It features 1120(224x5) SPUs as well as 56 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 5830 is 135% quicker than the GeForce GT 340 overall, because of its higher data rate. (explain)
Texel RateThe Radeon HD 5830 should be quite a bit (about 155%) better at AF than the GeForce GT 340. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 5830 is superior to the GeForce GT 340, and very much so. (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 max amount of data (measured in MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
