Compare any two graphics cards:
Radeon HD 4550 256MB vs Radeon R9 M280X
IntroThe Radeon HD 4550 256MB comes with a GPU core clock speed of 600 MHz, and the 256 MB of DDR3 RAM is set to run at 800 MHz through a 64-bit bus. It also is comprised of 80(16x5) SPUs, 8 TAUs, and 4 ROPs.Compare all of that to the Radeon R9 M280X, which comes with a core clock speed of 900 MHz and a GDDR5 memory speed of 1375 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 M280X should perform quite a bit faster than the Radeon HD 4550 256MB overall. (explain)
Texel RateThe Radeon R9 M280X should be a lot (about 950%) better at anisotropic filtering than the Radeon HD 4550 256MB. (explain)
Pixel RateThe Radeon R9 M280X will be a lot (more or less 500%) faster with regards to full screen anti-aliasing than the Radeon HD 4550 256MB, and also will be able to handle higher screen resolutions without slowing down too much. (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 transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If 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 amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
