Compare any two graphics cards:
GeForce GT 220 GDDR3 vs Radeon HD 3470 512MB
IntroThe GeForce GT 220 GDDR3 comes with core clock speeds of 625 MHz on the GPU, and 1012 MHz on the 512 MB of GDDR3 memory. It features 48 SPUs along with 16 TAUs and 8 Rasterization Operator Units.Compare those specs to the Radeon HD 3470 512MB, which comes with GPU clock speed of 800 MHz, and 512 MB of GDDR3 memory running at 950 MHz through a 128-bit bus. It also is comprised of 40(8x5) Stream Processors, 4 TAUs, and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce GT 220 GDDR3 will be 7% faster than the Radeon HD 3470 512MB in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce GT 220 GDDR3 is a lot (about 213%) better at texture filtering than the Radeon HD 3470 512MB. (explain)
Pixel RateThe GeForce GT 220 GDDR3 is quite a bit (approximately 56%) faster with regards to anti-aliasing than the Radeon HD 3470 512MB, and should be capable of handling higher 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: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied 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 better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
