Compare any two graphics cards:
Radeon HD 7850 vs Radeon R9 390X 8G
IntroThe Radeon HD 7850 uses a 28 nm design. AMD has set the core speed at 860 MHz. The GDDR5 RAM works at a frequency of 1200 MHz on this particular card. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.Compare all that to the Radeon R9 390X 8G, which features core speeds of 1050 MHz on the GPU, and 1500 MHz on the 8192 MB of GDDR5 RAM. It features 2816 SPUs as well as 176 Texture Address Units and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 390X 8G, in theory, should perform much faster than the Radeon HD 7850 overall. (explain)
Texel RateThe Radeon R9 390X 8G is quite a bit (about 236%) better at texture filtering than the Radeon HD 7850. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R9 390X 8G is the winner, by a large margin. (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 largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
