Compare any two graphics cards:
GeForce GTS 250 512MB vs Radeon HD 6750 1GB
IntroThe GeForce GTS 250 512MB comes with a clock speed of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also features a 256-bit bus, and makes use of a 65/55 nm design. It is comprised of 128 SPUs, 64 TAUs, and 16 ROPs.Compare those specs to the Radeon HD 6750 1GB, which has a GPU core clock speed of 725 MHz, and 1024 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is made up of 720 Stream Processors, 36 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTS 250 512MB will be 10% faster than the Radeon HD 6750 1GB in general, due to its higher data rate. (explain)
Texel RateThe GeForce GTS 250 512MB is quite a bit (about 81%) better at anisotropic filtering than the Radeon HD 6750 1GB. (explain)
Pixel RateThe GeForce GTS 250 512MB should be a little bit (about 2%) better at AA than the Radeon HD 6750 1GB, and will be capable of handling higher screen resolutions more effectively. (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 (measured in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 are processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
