Compare any two graphics cards:
Radeon R9 290 vs Radeon R9 390 8G
IntroThe Radeon R9 290 uses a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM is set to run at a speed of 1250 MHz on this particular card. It features 2560 SPUs along with 160 TAUs and 64 Rasterization Operator Units.Compare those specifications to the Radeon R9 390 8G, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 memory is set to run at a frequency of 1500 MHz on this specific card. It features 2560 SPUs as well as 160 Texture Address Units and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R9 390 8G should in theory be just a bit superior to the Radeon R9 290 overall. (explain)
Texel RateThe Radeon R9 390 8G will be quite a bit (approximately 25%) better at anisotropic filtering than the Radeon R9 290. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon R9 390 8G is superior to the Radeon R9 290, 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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 are processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
