Compare any two graphics cards:
GeForce GTX 660 vs Radeon R7 240
IntroThe GeForce GTX 660 uses a 28 nm design. nVidia has set the core speed at 980 MHz. The GDDR5 RAM is set to run at a speed of 1502 MHz on this particular card. It features 960 SPUs along with 80 Texture Address Units and 24 ROPs.Compare all that to the Radeon R7 240, which comes with a clock frequency of 730 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is made up of 320 SPUs, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 660 is 401% quicker than the Radeon R7 240 overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 660 is much (more or less 437%) better at anisotropic filtering than the Radeon R7 240. (explain)
Pixel RateThe GeForce GTX 660 will be much (approximately 303%) better at full screen anti-aliasing than the Radeon R7 240, and capable of handling higher 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 max amount of data (in units of megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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.
