Compare any two graphics cards:
Radeon HD 7870 XT vs Radeon R9 M290X
IntroThe Radeon HD 7870 XT has a GPU core speed of 925 MHz, and the 2048 MB of GDDR5 RAM runs at 1500 MHz through a 256-bit bus. It also is comprised of 1536 SPUs, 96 TAUs, and 32 Raster Operation Units.Compare all of that to the Radeon R9 M290X, which comes with a core clock speed of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also features a 256-bit memory bus, and uses a 28 nm design. It features 1280 SPUs, 80 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 7870 XT should in theory be a lot better than the Radeon R9 M290X overall. (explain)
Texel RateThe Radeon HD 7870 XT is much (more or less 31%) faster with regards to anisotropic filtering than the Radeon R9 M290X. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 7870 XT is superior to the Radeon R9 M290X, not by a very large margin though. (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 max amount of data (in units of MB per second) that can be transferred across 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, the result 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 anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount 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 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 write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 bandwidth is, the lower the potential to get to the max fill rate.
