Compare any two graphics cards:
Radeon R7 M260X vs Radeon R9 M270X
IntroThe Radeon R7 M260X makes use of a 28 nm design. AMD has clocked the core frequency at 825 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this card. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.Compare all that to the Radeon R9 M270X, which features GPU core speed of 725 MHz, and 2048 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R9 M270X will be 13% quicker than the Radeon R7 M260X overall, due to its greater bandwidth. (explain)
Texel RateThe Radeon R9 M270X should be a lot (more or less 46%) faster with regards to AF than the Radeon R7 M260X. (explain)
Pixel RateThe Radeon R9 M270X should be a lot (approximately 76%) better at anti-aliasing than the Radeon R7 M260X, and should be able to handle higher resolutions more effectively. (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 MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
