Compare any two graphics cards:
Radeon HD 5570 vs Radeon R9 M280X
IntroThe Radeon HD 5570 features a GPU clock speed of 650 MHz, and the 512 MB of DDR3 memory runs at 900 MHz through a 128-bit bus. It also features 400(80x5) Stream Processors, 20 TAUs, and 8 Raster Operation Units.Compare all that to the Radeon R9 M280X, which comes with a GPU core clock speed of 900 MHz, and 4096 MB of GDDR5 RAM set to run at 1375 MHz through a 128-bit bus. It also is comprised of 896 Stream Processors, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 M280X should be 206% faster than the Radeon HD 5570 in general, due to its greater bandwidth. (explain)
Texel RateThe Radeon R9 M280X should be a lot (more or less 288%) better at AF than the Radeon HD 5570. (explain)
Pixel RateThe Radeon R9 M280X is much (more or less 177%) better at FSAA than the Radeon HD 5570, and also able to handle higher screen resolutions while still performing well. (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 (in units of megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock 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 is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
