Compare any two graphics cards:
Radeon R7 M265 vs Radeon R9 M270X
IntroThe Radeon R7 M265 comes with a GPU core speed of 725 MHz, and the 2048 MB of DDR3 memory runs at 1000 MHz through a 128-bit bus. It also features 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon R9 M270X, which features GPU core speed of 725 MHz, and 2048 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the Radeon R9 M270X should be much faster than the Radeon R7 M265 in general. (explain)
Texel RateThe Radeon R9 M270X should be a lot (approximately 67%) better at anisotropic filtering than the Radeon R7 M265. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 M270X is a better choice, by a large margin. (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 megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units by the core clock 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 applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
