Compare any two graphics cards:
Radeon HD 3870 1GB vs Radeon R9 M370X
IntroThe Radeon HD 3870 1GB features a core clock frequency of 775 MHz and a GDDR4 memory frequency of 1125 MHz. It also features a 256-bit bus, and makes use of a 55 nm design. It features 320(64x5) SPUs, 16 TAUs, and 16 ROPs.Compare all of that to the Radeon R9 M370X, which comes with GPU clock speed of 800 MHz, and 2048 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have exactly the same bandwidth, so in theory they should perform exactly the same. (explain)
Texel RateThe Radeon R9 M370X is a lot (more or less 158%) more effective at anisotropic filtering than the Radeon HD 3870 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 M370X is superior to the Radeon HD 3870 1GB, but it probably won't make a huge difference. (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 largest amount of information (in units of MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many 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.
