Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs Radeon R7 250X
IntroThe GeForce 8800 GTS (G80) 640MB comes with a clock frequency of 513 MHz and a GDDR3 memory frequency of 792 MHz. It also makes use of a 320-bit memory bus, and makes use of a 90 nm design. It features 96 SPUs, 48 TAUs, and 20 ROPs.Compare those specifications to the Radeon R7 250X, which features a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R7 250X is 14% faster than the GeForce 8800 GTS (G80) 640MB in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon R7 250X is a lot (approximately 62%) better at texture filtering than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon R7 250X is superior to the GeForce 8800 GTS (G80) 640MB, and very much so. (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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics 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 that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
