Compare any two graphics cards:
Radeon HD 4830 512MB vs Radeon R7 M260X
IntroThe Radeon HD 4830 512MB uses a 55 nm design. AMD has set the core frequency at 575 MHz. The GDDR3 memory works at a speed of 900 MHz on this particular card. It features 640(128x5) SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.Compare those specifications to the Radeon R7 M260X, which has a clock frequency of 825 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon R7 M260X should theoretically be a little bit superior to the Radeon HD 4830 512MB in general. (explain)
Texel RateThe Radeon R7 M260X should be just a bit (about 8%) more effective at AF than the Radeon HD 4830 512MB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 4830 512MB is superior to the Radeon R7 M260X, 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 max amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of 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 also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
