Compare any two graphics cards:
Radeon R7 M265 vs Radeon R9 270
IntroThe Radeon R7 M265 has a clock frequency of 725 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is comprised of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon R9 270, which comes with a clock frequency of 900 MHz and a GDDR5 memory frequency of 1400 MHz. It also features a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1280 SPUs, 80 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R9 270, in theory, should be quite a bit faster than the Radeon R7 M265 overall. (explain)
Texel RateThe Radeon R9 270 will be much (approximately 314%) more effective at AF than the Radeon R7 M265. (explain)
Pixel RateThe Radeon R9 270 will be much (about 397%) more effective at anti-aliasing than the Radeon R7 M265, and will be able to handle higher screen resolutions without losing too much performance. (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 information (counted in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 are applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the 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 number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
