Compare any two graphics cards:
Radeon R9 290 vs Radeon R9 390X 8G
IntroThe Radeon R9 290 features a GPU core clock speed of 800 MHz, and the 4096 MB of GDDR5 memory is set to run at 1250 MHz through a 512-bit bus. It also is made up of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.
Compare those specifications to the Radeon R9 390X 8G, which comes with core clock speeds of 1050 MHz on the GPU, and 1500 MHz on the 8192 MB of GDDR5 memory. It features 2816 SPUs along with 176 TAUs and 64 Rasterization Operator Units.

The Radeon R9 390X 8G should in theory perform just a bit faster than the Radeon R9 290 in general. (explain)
Texel RateThe Radeon R9 390X 8G will be quite a bit (more or less 44%) better at anisotropic filtering than the Radeon R9 290. (explain)
Pixel RateIf running with 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 number 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 higher the texel rate, 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 most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. 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 lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
