Compare any two graphics cards:
Radeon HD 3870 X2 512MB vs Radeon R9 M375
IntroThe Radeon HD 3870 X2 512MB makes use of a 55 nm design. AMD has clocked the core frequency at 825 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this specific model. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 ROPs.Compare those specifications to the Radeon R9 M375, which makes use of a 28 nm design. AMD has set the core speed at 1015 MHz. The DDR3 memory works at a speed of 1100 MHz on this particular card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon HD 3870 X2 512MB should perform a lot faster than the Radeon R9 M375 in general. (explain)
Texel RateThe Radeon R9 M375 will be quite a bit (more or less 54%) more effective at anisotropic filtering than the Radeon HD 3870 X2 512MB. (explain)
Pixel RateThe Radeon HD 3870 X2 512MB should be quite a bit (about 63%) faster with regards to anti-aliasing than the Radeon R9 M375, and also 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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher 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 a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 ability to get to the maximum fill rate.
