Compare any two graphics cards:
Radeon HD 3850 X2 vs Radeon R9 M395X
IntroThe Radeon HD 3850 X2 uses a 55 nm design. AMD has set the core frequency at 668 MHz. The GDDR3 memory is set to run at a frequency of 828 MHz on this specific card. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 ROPs.Compare all of that to the Radeon R9 M395X, which features core clock speeds of 723 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R9 M395X will be 51% faster than the Radeon HD 3850 X2 in general, because of its greater data rate. (explain)
Texel RateThe Radeon R9 M395X will be much (more or less 333%) faster with regards to texture filtering than the Radeon HD 3850 X2. (explain)
Pixel RateThe Radeon R9 M395X will be a bit (approximately 8%) more effective at FSAA than the Radeon HD 3850 X2, and should be capable of handling higher resolutions better. (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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core 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 processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
