Compare any two graphics cards:
GeForce GTX 260 vs Radeon HD 6750 1GB
IntroThe GeForce GTX 260 makes use of a 65 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 RAM is set to run at a speed of 999 MHz on this particular card. It features 192 SPUs along with 64 Texture Address Units and 28 ROPs.Compare those specifications to the Radeon HD 6750 1GB, which comes with GPU core speed of 725 MHz, and 1024 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also features 720 SPUs, 36 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 260, in theory, should perform much faster than the Radeon HD 6750 1GB in general. (explain)
Texel RateThe GeForce GTX 260 will be quite a bit (approximately 41%) better at texture filtering than the Radeon HD 6750 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 260 is the winner, and very much so. (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 moved over the external memory interface in one second. The number is calculated by multiplying the bus 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 anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write 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 clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
