Compare any two graphics cards:
GeForce GTS 450 vs Radeon HD 3650 256MB
IntroThe GeForce GTS 450 makes use of a 40 nm design. nVidia has clocked the core speed at 783 MHz. The GDDR5 memory is set to run at a frequency of 902 MHz on this model. It features 192 SPUs as well as 32 Texture Address Units and 16 ROPs.Compare those specs to the Radeon HD 3650 256MB, which comes with clock speeds of 725 MHz on the GPU, and 800 MHz on the 256 MB of DDR2 memory. It features 120(24x5) SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTS 450 should be 126% quicker than the Radeon HD 3650 256MB overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTS 450 is quite a bit (more or less 332%) better at texture filtering than the Radeon HD 3650 256MB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTS 450 is a better choice, and very much so. (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 max amount of information (measured in MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
