Compare any two graphics cards:
Radeon HD 3470 512MB vs Radeon R9 M270X
IntroThe Radeon HD 3470 512MB has a core clock frequency of 800 MHz and a GDDR3 memory frequency of 950 MHz. It also features a 128-bit memory bus, and makes use of a 55 nm design. It is comprised of 40(8x5) SPUs, 4 TAUs, and 4 ROPs.Compare those specs to the Radeon R9 M270X, which features a core clock frequency of 725 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R9 M270X, in theory, should perform much faster than the Radeon HD 3470 512MB overall. (explain)
Texel RateThe Radeon R9 M270X is quite a bit (about 806%) faster with regards to AF than the Radeon HD 3470 512MB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon R9 M270X is a better choice, 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 max amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 are processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
