Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs Radeon R9 380 4G
IntroThe GeForce 8800 GTS (G80) 640MB comes with a core clock speed of 513 MHz and a GDDR3 memory frequency of 792 MHz. It also features a 320-bit memory bus, and makes use of a 90 nm design. It is comprised of 96 SPUs, 48 TAUs, and 20 Raster Operation Units.Compare that to the Radeon R9 380 4G, which comes with a core clock speed of 970 MHz and a GDDR5 memory speed of 1425 MHz. It also makes use of a 256-bit memory bus, and makes use of a 28 nm design. It is made up of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R9 380 4G should theoretically be a lot better than the GeForce 8800 GTS (G80) 640MB overall. (explain)
Texel RateThe Radeon R9 380 4G should be quite a bit (about 341%) faster with regards to anisotropic filtering than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateThe Radeon R9 380 4G should be quite a bit (about 203%) faster with regards to anti-aliasing than the GeForce 8800 GTS (G80) 640MB, and should be capable of handling higher resolutions better. (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 data (measured in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
