Compare any two graphics cards:
GeForce 8800 GT 256MB vs Radeon R9 M390X
IntroThe GeForce 8800 GT 256MB has a GPU clock speed of 600 MHz, and the 256 MB of GDDR3 RAM runs at 700 MHz through a 256-bit bus. It also features 112 Stream Processors, 56 Texture Address Units, and 16 Raster Operation Units.Compare all that to the Radeon R9 M390X, which has clock speeds of 723 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 M390X should be 257% faster than the GeForce 8800 GT 256MB in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon R9 M390X is quite a bit (approximately 175%) better at AF than the GeForce 8800 GT 256MB. (explain)
Pixel RateThe Radeon R9 M390X will be a lot (about 141%) better at anti-aliasing than the GeForce 8800 GT 256MB, and capable of handling higher 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 maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
