Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs Radeon R9 M275X
IntroThe GeForce 8600 GT 512MB DDR2 comes with a GPU core speed of 540 MHz, and the 512 MB of DDR2 memory is set to run at 400 MHz through a 128-bit bus. It also features 32 SPUs, 16 TAUs, and 8 ROPs.Compare those specifications to the Radeon R9 M275X, which features a GPU core clock speed of 900 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 M275X is 463% quicker than the GeForce 8600 GT 512MB DDR2 overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon R9 M275X should be much (about 317%) more effective at texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateThe Radeon R9 M275X should be a lot (more or less 233%) faster with regards to AA than the GeForce 8600 GT 512MB DDR2, and also will be capable of handling higher screen resolutions without losing too much performance. (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 information (counted in megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen 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 number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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 reach the maximum fill rate.
