Compare any two graphics cards:
Radeon HD 3850 X2 vs Radeon R9 M385X
IntroThe Radeon HD 3850 X2 has a GPU core clock speed of 668 MHz, and the 512 MB of GDDR3 RAM runs at 828 MHz through a 256-bit bus. It also is made up of 320(64x5) Stream Processors, 16 TAUs, and 16 ROPs.Compare that to the Radeon R9 M385X, which uses a 28 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 RAM works at a speed of 1500 MHz on this particular model. It features 896 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon HD 3850 X2 should theoretically be just a bit superior to the Radeon R9 M385X overall. (explain)
Texel RateThe Radeon R9 M385X will be quite a bit (about 188%) more effective at texture filtering than the Radeon HD 3850 X2. (explain)
Pixel RateThe Radeon HD 3850 X2 will be a lot (more or less 21%) faster with regards to FSAA than the Radeon R9 M385X, and also should be capable of handling higher screen resolutions without losing too much performance. (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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported across 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 RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out 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 outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
