Compare any two graphics cards:
GeForce 8800 GTX vs Radeon R7 250
IntroThe GeForce 8800 GTX comes with a GPU core clock speed of 575 MHz, and the 768 MB of GDDR3 memory is set to run at 900 MHz through a 384-bit bus. It also is made up of 128 SPUs, 64 TAUs, and 24 ROPs.Compare that to the Radeon R7 250, which comes with clock speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 8800 GTX should perform just a bit faster than the Radeon R7 250 overall. (explain)
Texel RateThe GeForce 8800 GTX is much (more or less 53%) better at texture filtering than the Radeon R7 250. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 8800 GTX 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 (in units of MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
