Compare any two graphics cards:
GeForce GTX 260 vs Radeon R9 M290X
IntroThe GeForce GTX 260 makes use of a 65 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 memory works at a frequency of 999 MHz on this model. It features 192 SPUs as well as 64 Texture Address Units and 28 ROPs.Compare those specifications to the Radeon R9 M290X, which comes with GPU clock speed of 850 MHz, and 4096 MB of GDDR5 memory running at 1200 MHz through a 256-bit bus. It also is comprised of 1280 SPUs, 80 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 M290X should theoretically perform much faster than the GeForce GTX 260 overall. (explain)
Texel RateThe Radeon R9 M290X should be quite a bit (more or less 84%) better at texture filtering than the GeForce GTX 260. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon R9 M290X is the winner, by a large margin. (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 max amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 are applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
