Compare any two graphics cards:
GeForce GTS 250 512MB vs Radeon HD 4730
IntroThe GeForce GTS 250 512MB features a clock frequency of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also uses a 256-bit bus, and uses a 65/55 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 4730, which comes with a GPU core clock speed of 700 MHz, and 512 MB of GDDR5 memory running at 900 MHz through a 128-bit bus. It also is comprised of 640(128x5) Stream Processors, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTS 250 512MB is 22% faster than the Radeon HD 4730 in general, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTS 250 512MB should be much (more or less 111%) better at texture filtering than the Radeon HD 4730. (explain)
Pixel RateThe GeForce GTS 250 512MB is a lot (about 111%) faster with regards to anti-aliasing than the Radeon HD 4730, and will 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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 can be processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
