Compare any two graphics cards:
GeForce GT 320 vs Radeon HD 5450
IntroThe GeForce GT 320 makes use of a 40 nm design. nVidia has set the core frequency at 540 MHz. The GDDR3 RAM works at a speed of 790 MHz on this model. It features 72 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.Compare all that to the Radeon HD 5450, which features a core clock speed of 650 MHz and a DDR3 memory frequency of 800 MHz. It also uses a 64-bit bus, and uses a 40 nm design. It features 80(16x5) SPUs, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 320 should be 98% quicker than the Radeon HD 5450 in general, due to its greater data rate. (explain)
Texel RateThe GeForce GT 320 is much (about 149%) better at texture filtering than the Radeon HD 5450. (explain)
Pixel RateThe GeForce GT 320 is a lot (more or less 66%) faster with regards to AA than the Radeon HD 5450, and also will be able to handle higher screen resolutions while still performing well. (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 (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the 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 most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
