Compare any two graphics cards:
Radeon HD 4850 512MB vs Radeon R7 M260X
IntroThe Radeon HD 4850 512MB has a GPU core clock speed of 625 MHz, and the 512 MB of GDDR3 memory runs at 993 MHz through a 256-bit bus. It also is made up of 800(160x5) Stream Processors, 40 TAUs, and 16 Raster Operation Units.Compare all that to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has clocked the core speed at 825 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this card. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R7 M260X should theoretically perform just a bit faster than the Radeon HD 4850 512MB overall. (explain)
Texel RateThe Radeon HD 4850 512MB is a lot (about 26%) better at texture filtering than the Radeon R7 M260X. (explain)
Pixel RateThe Radeon HD 4850 512MB is much (about 52%) better at anti-aliasing than the Radeon R7 M260X, and capable of handling higher 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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
