Compare any two graphics cards:
GeForce 8600 GT 512MB GDDR3 vs Radeon R7 250X 2GB
IntroThe GeForce 8600 GT 512MB GDDR3 features a GPU 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 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare that to the Radeon R7 250X 2GB, which has a GPU core clock speed of 1000 MHz, and 2048 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R7 250X 2GB will be 221% faster than the GeForce 8600 GT 512MB GDDR3 in general, due to its greater bandwidth. (explain)
Texel RateThe Radeon R7 250X 2GB will be much (approximately 363%) more effective at AF than the GeForce 8600 GT 512MB GDDR3. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon R7 250X 2GB 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 max amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type 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 AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, 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 amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's 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 rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
