Compare any two graphics cards:
Radeon R9 290 vs Radeon R9 390X 8G
IntroThe Radeon R9 290 features a clock frequency of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 512-bit bus, and makes use of a 28 nm design. It is made up of 2560 SPUs, 160 TAUs, and 64 ROPs.Compare those specs to the Radeon R9 390X 8G, which features a GPU core clock speed of 1050 MHz, and 8192 MB of GDDR5 RAM set to run at 1500 MHz through a 512-bit bus. It also is made up of 2816 Stream Processors, 176 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R9 390X 8G should theoretically be a small bit better than the Radeon R9 290 overall. (explain)
Texel RateThe Radeon R9 390X 8G will be quite a bit (approximately 44%) better at anisotropic filtering than the Radeon R9 290. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon R9 390X 8G is superior to the Radeon R9 290, by far. (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 largest amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card 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 colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
