Compare any two graphics cards:
GeForce GTX 280 vs Radeon R9 M385X
IntroThe GeForce GTX 280 uses a 65 nm design. nVidia has clocked the core speed at 602 MHz. The GDDR3 memory is set to run at a speed of 1107 MHz on this specific model. It features 240 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.Compare all of that to the Radeon R9 M385X, which comes with a core clock speed of 1100 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the GeForce GTX 280 should be a lot faster than the Radeon R9 M385X overall. (explain)
Texel RateThe Radeon R9 M385X is quite a bit (approximately 28%) more effective at AF than the GeForce GTX 280. (explain)
Pixel RateThe GeForce GTX 280 is a bit (more or less 9%) better at full screen anti-aliasing than the Radeon R9 M385X, and also should be 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 maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
