Compare any two graphics cards:
Radeon HD 6770 1GB vs Radeon R9 M270X
IntroThe Radeon HD 6770 1GB has a GPU core speed of 900 MHz, and the 1024 MB of GDDR5 RAM runs at 1050 MHz through a 128-bit bus. It also features 800 SPUs, 40 Texture Address Units, and 16 ROPs.Compare those specifications to the Radeon R9 M270X, which makes use of a 28 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon R9 M270X should theoretically be a small bit better than the Radeon HD 6770 1GB overall. (explain)
Texel RateThe Radeon HD 6770 1GB should be much (about 24%) better at anisotropic filtering than the Radeon R9 M270X. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 6770 1GB is superior to the Radeon R9 M270X, 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 maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed 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. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
