Compare any two graphics cards:
Radeon HD 6950 2GB vs Radeon R9 M390X
IntroThe Radeon HD 6950 2GB uses a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM runs at a speed of 1250 MHz on this card. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.Compare those specifications to the Radeon R9 M390X, which makes use of a 28 nm design. AMD has set the core speed at 723 MHz. The GDDR5 memory is set to run at a speed of 1250 MHz on this particular card. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same memory bandwidth, so in theory they should have the same performance. (explain)
Texel RateThe Radeon R9 M390X should be a lot (more or less 31%) more effective at anisotropic filtering than the Radeon HD 6950 2GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 6950 2GB is a better choice, 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 information (measured in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
