Compare any two graphics cards:
Radeon HD 4650 512MB vs Radeon R7 M260
IntroThe Radeon HD 4650 512MB features a clock frequency of 600 MHz and a DDR2 memory frequency of 500 MHz. It also features a 128-bit memory bus, and makes use of a 55 nm design. It is made up of 320(64x5) SPUs, 32 TAUs, and 8 ROPs.Compare all of that to the Radeon R7 M260, which features a core clock frequency of 715 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 64-bit memory bus, and uses a 28 nm design. It features 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have exactly the same memory bandwidth, so theoretically they should have identical performance. (explain)
Texel RateThe Radeon HD 4650 512MB is a small bit (about 12%) faster with regards to AF than the Radeon R7 M260. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon R7 M260 is a better choice, though only just barely. (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 max amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should 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 anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
