Compare any two graphics cards:
GeForce 9500 GT 1GB GDDR3 vs Radeon HD 3650 256MB
IntroThe GeForce 9500 GT 1GB GDDR3 has a GPU core speed of 550 MHz, and the 1024 MB of GDDR3 RAM is set to run at 800 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 TAUs, and 8 ROPs.Compare that to the Radeon HD 3650 256MB, which uses a 55 nm design. AMD has set the core frequency at 725 MHz. The DDR2 RAM is set to run at a frequency of 800 MHz on this specific card. It features 120(24x5) SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same bandwidth, so in theory they should have the same performance. (explain)
Texel RateThe GeForce 9500 GT 1GB GDDR3 should be a lot (approximately 52%) better at texture filtering than the Radeon HD 3650 256MB. (explain)
Pixel RateThe GeForce 9500 GT 1GB GDDR3 is quite a bit (about 52%) better at FSAA than the Radeon HD 3650 256MB, and also should be able to handle higher screen resolutions more effectively. (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 moved over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once 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 AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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 potential to get to the max fill rate.
