Compare any two graphics cards:
GeForce GTX 660 Ti vs Radeon HD 5670
IntroThe GeForce GTX 660 Ti features a core clock speed of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also makes use of a 192-bit memory bus, and makes use of a 28 nm design. It is comprised of 1344 SPUs, 112 TAUs, and 24 ROPs.Compare those specifications to the Radeon HD 5670, which makes use of a 40 nm design. AMD has clocked the core frequency at 775 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this particular model. It features 400(80x5) SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 660 Ti should theoretically be much better than the Radeon HD 5670 in general. (explain)
Texel RateThe GeForce GTX 660 Ti should be a lot (approximately 561%) more effective at AF than the Radeon HD 5670. (explain)
Pixel RateThe GeForce GTX 660 Ti will be quite a bit (about 254%) more effective at AA than the Radeon HD 5670, 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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should 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 anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
