Compare any two graphics cards:
GeForce GTX 280 vs Radeon R7 240
IntroThe GeForce GTX 280 uses a 65 nm design. nVidia has clocked the core frequency at 602 MHz. The GDDR3 RAM runs at a frequency of 1107 MHz on this particular model. It features 240 SPUs along with 80 TAUs and 32 Rasterization Operator Units.Compare all of that to the Radeon R7 240, which features a core clock frequency of 730 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 128-bit memory bus, and makes use of 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 BandwidthThe GeForce GTX 280 should theoretically perform much faster than the Radeon R7 240 in general. (explain)
Texel RateThe GeForce GTX 280 is a lot (more or less 230%) more effective at AF than the Radeon R7 240. (explain)
Pixel RateThe GeForce GTX 280 will be a lot (approximately 230%) better at full screen anti-aliasing than the Radeon R7 240, and will be capable of handling higher screen resolutions without losing too much performance. (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 maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 can be processed per second. This is calculated by multiplying the total texture units by the core clock 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 maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. 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 output 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.
