Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs Radeon R7 250X
IntroThe GeForce 8800 GTS (G80) 640MB has a GPU core speed of 513 MHz, and the 640 MB of GDDR3 memory runs at 792 MHz through a 320-bit bus. It also is comprised of 96 SPUs, 48 Texture Address Units, and 20 Raster Operation Units.Compare all of that to the Radeon R7 250X, which features a GPU core clock speed of 1000 MHz, and 1024 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R7 250X should theoretically be a small bit better than the GeForce 8800 GTS (G80) 640MB in general. (explain)
Texel RateThe Radeon R7 250X should be a lot (more or less 62%) better at texture filtering than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateThe Radeon R7 250X is quite a bit (more or less 56%) better at anti-aliasing than the GeForce 8800 GTS (G80) 640MB, and able to handle higher screen resolutions more effectively. (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 transferred past the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
