Compare any two graphics cards:
Radeon HD 6850 vs Radeon R9 M390X
IntroThe Radeon HD 6850 uses a 40 nm design. AMD has set the core speed at 775 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this specific model. It features 960 SPUs as well as 48 TAUs and 32 ROPs.Compare all of that 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 is set to run at a speed of 1250 MHz on this particular card. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon R9 M390X should perform a lot faster than the Radeon HD 6850 overall. (explain)
Texel RateThe Radeon R9 M390X should be quite a bit (approximately 149%) faster with regards to texture filtering than the Radeon HD 6850. (explain)
Pixel RateThe Radeon HD 6850 should be a small bit (more or less 7%) faster with regards to anti-aliasing than the Radeon R9 M390X, and capable of handling higher resolutions while still performing well. (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 largest amount of information (measured in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If 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 high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 ability to reach the maximum fill rate.
