Compare any two graphics cards:
Radeon HD 6970 vs Radeon R9 M390X
IntroThe Radeon HD 6970 features a GPU core clock speed of 880 MHz, and the 2048 MB of GDDR5 RAM runs at 1375 MHz through a 256-bit bus. It also is made up of 1536 SPUs, 96 Texture Address Units, and 32 ROPs.Compare those specifications to the Radeon R9 M390X, which makes use of a 28 nm design. AMD has clocked the core frequency at 723 MHz. The GDDR5 RAM works at a speed of 1250 MHz on this model. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6970 should theoretically perform a little bit faster than the Radeon R9 M390X overall. (explain)
Texel RateThe Radeon R9 M390X is a little bit (more or less 10%) faster with regards to AF than the Radeon HD 6970. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 6970 is the winner, 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 largest amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, 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, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
