Compare any two graphics cards:
GeForce GTX 750 vs Radeon R9 M270X
IntroThe GeForce GTX 750 features a GPU core speed of 1020 MHz, and the 1024 MB of GDDR5 RAM runs at 1250 MHz through a 128-bit bus. It also is comprised of 512 Stream Processors, 32 Texture Address Units, and 16 ROPs.Compare all of that to the Radeon R9 M270X, which uses a 28 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this specific model. It features 640 SPUs along with 40 TAUs and 16 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce GTX 750 is 11% quicker than the Radeon R9 M270X in general, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 750 will be just a bit (more or less 13%) better at AF than the Radeon R9 M270X. (explain)
Pixel RateThe GeForce GTX 750 is a lot (more or less 41%) better at anti-aliasing than the Radeon R9 M270X, and should be able to handle 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 max amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of 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 anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units 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 processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
