Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs Radeon R9 M275X
IntroThe GeForce 8800 GTS (G80) 320MB features a GPU core clock speed of 513 MHz, and the 320 MB of GDDR3 memory runs at 792 MHz through a 320-bit bus. It also features 96 Stream Processors, 48 Texture Address Units, and 20 ROPs.Compare that to the Radeon R9 M275X, which has a clock frequency of 900 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 M275X should in theory be a little bit faster than the GeForce 8800 GTS (G80) 320MB in general. (explain)
Texel RateThe Radeon R9 M275X will be much (about 46%) faster with regards to AF than the GeForce 8800 GTS (G80) 320MB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R9 M275X 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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling 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 card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
