Compare any two graphics cards:
Radeon HD 5550 vs Radeon R9 M270X
IntroThe Radeon HD 5550 uses a 40 nm design. AMD has clocked the core speed at 550 MHz. The DDR2 RAM works at a speed of 400 MHz on this model. It features 320(64x5) SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare those specifications to the Radeon R9 M270X, which uses a 28 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this model. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R9 M270X should theoretically perform quite a bit faster than the Radeon HD 5550 overall. (explain)
Texel RateThe Radeon R9 M270X will be much (about 230%) faster with regards to AF than the Radeon HD 5550. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon R9 M270X is superior to the Radeon HD 5550, 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 largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high 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 of the card by the core speed of the chip. The higher this number, the better the graphics 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 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. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
