Compare any two graphics cards:
Radeon HD 4830 1GB vs Radeon R9 M280X
IntroThe Radeon HD 4830 1GB comes with a GPU clock speed of 575 MHz, and the 1024 MB of GDDR4 memory is set to run at 900 MHz through a 256-bit bus. It also features 640(128x5) Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.Compare that to the Radeon R9 M280X, which uses a 28 nm design. AMD has clocked the core speed at 900 MHz. The GDDR5 RAM works at a speed of 1375 MHz on this specific card. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon R9 M280X should be a lot faster than the Radeon HD 4830 1GB in general. (explain)
Texel RateThe Radeon R9 M280X will be much (more or less 174%) better at texture filtering than the Radeon HD 4830 1GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R9 M280X is superior to the Radeon HD 4830 1GB, 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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at 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 the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
