Compare any two graphics cards:
GeForce GT 220 GDDR3 vs Radeon HD 3470 512MB
IntroThe GeForce GT 220 GDDR3 features a core clock frequency of 625 MHz and a GDDR3 memory frequency of 1012 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is made up of 48 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specs to the Radeon HD 3470 512MB, which has a GPU core clock speed of 800 MHz, and 512 MB of GDDR3 memory set to run at 950 MHz through a 128-bit bus. It also is comprised of 40(8x5) Stream Processors, 4 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce GT 220 GDDR3 should perform a little bit faster than the Radeon HD 3470 512MB overall. (explain)
Texel RateThe GeForce GT 220 GDDR3 is much (approximately 213%) better at texture filtering than the Radeon HD 3470 512MB. (explain)
Pixel RateThe GeForce GT 220 GDDR3 will be much (approximately 56%) better at anti-aliasing than the Radeon HD 3470 512MB, and should be capable of handling higher 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 largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
