Compare any two graphics cards:
GeForce 9800 GTX vs Radeon HD 4730
IntroThe GeForce 9800 GTX comes with a GPU clock speed of 675 MHz, and the 512 MB of GDDR3 memory runs at 1100 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 4730, which features a core clock speed of 700 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 128-bit bus, and makes use of a 55 nm design. It is comprised of 640(128x5) SPUs, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthThe GeForce 9800 GTX should theoretically be much faster than the Radeon HD 4730 overall. (explain)
Texel RateThe GeForce 9800 GTX should be quite a bit (more or less 93%) better at AF than the Radeon HD 4730. (explain)
Pixel RateThe GeForce 9800 GTX is a lot (approximately 93%) better at anti-aliasing than the Radeon HD 4730, and also should be able to handle higher screen 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: Bandwidth is the largest amount of data (counted in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card 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 maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
