Compare any two graphics cards:
Radeon HD 6950 vs Radeon R7 M260X
IntroThe Radeon HD 6950 uses a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory runs at a speed of 1250 MHz on this particular card. It features 1408 SPUs along with 88 Texture Address Units and 32 Rasterization Operator Units.Compare all that to the Radeon R7 M260X, which comes with GPU clock speed of 825 MHz, and 2048 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is made up of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the Radeon HD 6950 should be quite a bit faster than the Radeon R7 M260X in general. (explain)
Texel RateThe Radeon HD 6950 should be much (approximately 256%) more effective at AF than the Radeon R7 M260X. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 6950 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: Bandwidth is the max amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
