Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 6750
IntroThe GeForce GTX 550 Ti makes use of a 40 nm design. nVidia has clocked the core frequency at 900 MHz. The GDDR5 RAM runs at a speed of 1026 MHz on this model. It features 192 SPUs as well as 32 Texture Address Units and 24 Rasterization Operator Units.
Compare those specifications to the Radeon HD 6750, which features a clock speed of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is comprised of 720 SPUs, 36 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 550 Ti should be much faster than the Radeon HD 6750 in general. (explain)
Texel RateThe GeForce GTX 550 Ti should be a small bit (about 10%) more effective at texture filtering than the Radeon HD 6750. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 550 Ti is superior to the Radeon HD 6750, 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total 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 processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure 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 outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
