Compare any two graphics cards:
GeForce GTX 280 vs Radeon R9 M290X
IntroThe GeForce GTX 280 makes use of a 65 nm design. nVidia has set the core frequency at 602 MHz. The GDDR3 RAM runs at a speed of 1107 MHz on this particular model. It features 240 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.Compare that to the Radeon R9 M290X, which has a GPU core clock speed of 850 MHz, and 4096 MB of GDDR5 RAM set to run at 1200 MHz through a 256-bit bus. It also features 1280 Stream Processors, 80 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 M290X is 8% faster than the GeForce GTX 280 in general, due to its higher bandwidth. (explain)
Texel RateThe Radeon R9 M290X will be quite a bit (more or less 41%) more effective at texture filtering than the GeForce GTX 280. (explain)
Pixel RateThe Radeon R9 M290X will be quite a bit (more or less 41%) faster with regards to AA than the GeForce GTX 280, and will be capable of handling higher resolutions better. (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 (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better 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 maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 memory bandwidth is, the lower the ability to get to the maximum fill rate.
