Compare any two graphics cards:
Radeon HD 4750 vs Radeon R7 M260X
IntroThe Radeon HD 4750 has a GPU core clock speed of 730 MHz, and the 512 MB of GDDR5 memory is set to run at 800 MHz through a 128-bit bus. It also features 640(128x5) SPUs, 32 TAUs, and 16 Raster Operation Units.Compare that to the Radeon R7 M260X, which has core speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R7 M260X, in theory, should perform much faster than the Radeon HD 4750 in general. (explain)
Texel RateThe Radeon HD 4750 should be a small bit (more or less 18%) more effective at AF than the Radeon R7 M260X. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 4750 is a better choice, 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 data (in units of MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units by the core clock 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 applied in one second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
