Compare any two graphics cards:
Radeon R7 370 4G vs Radeon R9 390 8G
IntroThe Radeon R7 370 4G comes with clock speeds of 975 MHz on the GPU, and 1400 MHz on the 4096 MB of GDDR5 RAM. It features 1024 SPUs along with 64 TAUs and 32 ROPs.Compare those specs to the Radeon R9 390 8G, which uses a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM is set to run at a speed of 1500 MHz on this model. It features 2560 SPUs along with 160 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 390 8G should perform a lot faster than the Radeon R7 370 4G overall. (explain)
Texel RateThe Radeon R9 390 8G should be quite a bit (more or less 156%) better at texture filtering than the Radeon R7 370 4G. (explain)
Pixel RateThe Radeon R9 390 8G will be much (more or less 105%) more effective at anti-aliasing than the Radeon R7 370 4G, and also should be able to handle higher screen 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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video 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 maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
