Compare any two graphics cards:
GeForce 9600 GSO ASUS 512 vs Radeon HD 4650 512MB
IntroThe GeForce 9600 GSO ASUS 512 makes use of a 65 nm design. nVidia has clocked the core frequency at 550 MHz. The DDR2 RAM is set to run at a frequency of 500 MHz on this specific model. It features 96 SPUs along with 48 Texture Address Units and 12 Rasterization Operator Units.Compare that to the Radeon HD 4650 512MB, which uses a 55 nm design. AMD has clocked the core speed at 600 MHz. The DDR2 memory is set to run at a frequency of 500 MHz on this particular model. It features 320(64x5) SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same bandwidth, so in theory they should have identical performance. (explain)
Texel RateThe GeForce 9600 GSO ASUS 512 will be quite a bit (about 38%) faster with regards to texture filtering than the Radeon HD 4650 512MB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 9600 GSO ASUS 512 is a better choice, by far. (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 largest amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If 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 amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock 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 output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
