Compare any two graphics cards:
Radeon HD 3470 256MB vs Radeon R9 M380
IntroThe Radeon HD 3470 256MB has a clock speed of 800 MHz and a DDR2 memory speed of 950 MHz. It also uses a 128-bit bus, and makes use of a 55 nm design. It is made up of 40(8x5) SPUs, 4 Texture Address Units, and 4 Raster Operation Units.Compare all of that to the Radeon R9 M380, which comes with a GPU core clock speed of 1000 MHz, and 4096 MB of GDDR5 memory running at 1500 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 TAUs, and 16 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon R9 M380 should theoretically be quite a bit better than the Radeon HD 3470 256MB overall. (explain)
Texel RateThe Radeon R9 M380 is much (more or less 1150%) faster with regards to anisotropic filtering than the Radeon HD 3470 256MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 M380 is a better choice, by a large margin. (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 maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 can be processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). 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.
