Compare any two graphics cards:
GeForce 8600 GT 512MB GDDR3 vs Radeon R9 M275X
IntroThe GeForce 8600 GT 512MB GDDR3 features a GPU core clock speed of 540 MHz, and the 512 MB of GDDR3 memory runs at 700 MHz through a 128-bit bus. It also is comprised of 32 Stream Processors, 16 TAUs, and 8 Raster Operation Units.Compare that to the Radeon R9 M275X, which makes use of a 28 nm design. AMD has clocked the core speed at 900 MHz. The GDDR5 RAM runs at a frequency of 1125 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 M275X should be 221% quicker than the GeForce 8600 GT 512MB GDDR3 in general, because of its greater data rate. (explain)
Texel RateThe Radeon R9 M275X is quite a bit (approximately 317%) faster with regards to texture filtering than the GeForce 8600 GT 512MB GDDR3. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon R9 M275X is the winner, by far. (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 maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
