Compare any two graphics cards:
GeForce 8400 GS 512MB vs Radeon HD 5830
IntroThe GeForce 8400 GS 512MB features core clock speeds of 650 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 16 SPUs along with 8 TAUs and 4 Rasterization Operator Units.Compare all that to the Radeon HD 5830, which comes with a core clock speed of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It is comprised of 1120(224x5) SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 5830 should perform much faster than the GeForce 8400 GS 512MB in general. (explain)
Texel RateThe Radeon HD 5830 is a lot (approximately 762%) faster with regards to texture filtering than the GeForce 8400 GS 512MB. (explain)
Pixel RateThe Radeon HD 5830 is much (about 392%) more effective at full screen anti-aliasing than the GeForce 8400 GS 512MB, and should be capable of handling higher screen 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 maximum amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
