Compare any two graphics cards:
GeForce 8600 GT 1GB GDDR3 vs Radeon HD 3650 512MB
IntroThe GeForce 8600 GT 1GB GDDR3 comes with clock speeds of 540 MHz on the GPU, and 700 MHz on the 1024 MB of GDDR3 RAM. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.Compare all that to the Radeon HD 3650 512MB, which features GPU core speed of 725 MHz, and 512 MB of GDDR3 memory set to run at 800 MHz through a 128-bit bus. It also features 120(24x5) SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 3650 512MB should theoretically be a little bit faster than the GeForce 8600 GT 1GB GDDR3 in general. (explain)
Texel RateThe GeForce 8600 GT 1GB GDDR3 should be a lot (more or less 49%) faster with regards to AF than the Radeon HD 3650 512MB. (explain)
Pixel RateThe GeForce 8600 GT 1GB GDDR3 is much (about 49%) faster with regards to AA than the Radeon HD 3650 512MB, and also should be able to handle higher resolutions without losing too much performance. (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 (measured in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory 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 higher the bandwidth is, 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 number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
