Compare any two graphics cards:
GeForce GT 420 vs Radeon HD 3650 512MB
IntroThe GeForce GT 420 comes with a clock speed of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 48 SPUs, 8 TAUs, and 4 ROPs.Compare those specs to the Radeon HD 3650 512MB, which features a clock speed of 725 MHz and a GDDR3 memory frequency of 800 MHz. It also uses a 128-bit bus, and uses a 55 nm design. It is comprised of 120(24x5) SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 420, in theory, should perform a bit faster than the Radeon HD 3650 512MB in general. (explain)
Texel RateThe Radeon HD 3650 512MB will be a small bit (about 4%) better at AF than the GeForce GT 420. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 3650 512MB is the winner, though only just barely. (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 (in units of MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it 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 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 processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units 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 rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
