Compare any two graphics cards:
GeForce GTX 660 Ti vs Radeon HD 6950 2GB
IntroThe GeForce GTX 660 Ti features a GPU core speed of 915 MHz, and the 2048 MB of GDDR5 RAM runs at 1500 MHz through a 192-bit bus. It also is comprised of 1344 Stream Processors, 112 Texture Address Units, and 24 ROPs.Compare all of that to the Radeon HD 6950 2GB, which features core clock speeds of 800 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 memory. It features 1408 SPUs along with 88 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6950 2GB should in theory be a little bit better than the GeForce GTX 660 Ti overall. (explain)
Texel RateThe GeForce GTX 660 Ti is much (more or less 46%) better at anisotropic filtering than the Radeon HD 6950 2GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 6950 2GB is the winner, but it probably won't make a huge difference. (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 information (measured in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, 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 chip could possibly write to the 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 core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
