Compare any two graphics cards:
GeForce 8800 GT 512MB vs Radeon R9 390X 8G
IntroThe GeForce 8800 GT 512MB makes use of a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 RAM works at a speed of 900 MHz on this particular card. It features 112 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.Compare those specs to the Radeon R9 390X 8G, which has GPU core speed of 1050 MHz, and 8192 MB of GDDR5 memory running at 1500 MHz through a 512-bit bus. It also is made up of 2816 Stream Processors, 176 TAUs, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon R9 390X 8G should be a lot faster than the GeForce 8800 GT 512MB in general. (explain)
Texel RateThe Radeon R9 390X 8G is much (about 450%) faster with regards to texture filtering than the GeForce 8800 GT 512MB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R9 390X 8G is a better choice, 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: Bandwidth is the maximum amount of data (measured in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
