Compare any two graphics cards:
Radeon HD 4850 2GB vs Radeon R7 M260X
IntroThe Radeon HD 4850 2GB makes use of a 55 nm design. AMD has clocked the core frequency at 625 MHz. The GDDR4 memory runs at a speed of 993 MHz on this particular model. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.Compare all that to the Radeon R7 M260X, which features GPU core speed of 825 MHz, and 2048 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is made up of 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon R7 M260X should in theory be just a bit better than the Radeon HD 4850 2GB overall. (explain)
Texel RateThe Radeon HD 4850 2GB will be quite a bit (about 26%) faster with regards to texture filtering than the Radeon R7 M260X. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 4850 2GB is the winner, by far. (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 largest amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core 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 most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
