Compare any two graphics cards:
GeForce 9500 GT 1GB GDDR3 vs Radeon HD 3650 512MB
IntroThe GeForce 9500 GT 1GB GDDR3 makes use of a 55 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR3 memory works at a speed of 800 MHz on this particular card. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.Compare those specs to the Radeon HD 3650 512MB, which makes use of a 55 nm design. AMD has set the core speed at 725 MHz. The GDDR3 RAM runs at a speed of 800 MHz on this particular model. It features 120(24x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same memory bandwidth, so in theory they should have identical performance. (explain)
Texel RateThe GeForce 9500 GT 1GB GDDR3 is quite a bit (about 52%) better at AF than the Radeon HD 3650 512MB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 9500 GT 1GB GDDR3 is the winner, by a large margin. (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 information (in units of MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
