Compare any two graphics cards:
Radeon HD 3870 1GB vs Radeon R9 M370X
IntroThe Radeon HD 3870 1GB makes use of a 55 nm design. AMD has clocked the core frequency at 775 MHz. The GDDR4 RAM works at a speed of 1125 MHz on this model. It features 320(64x5) SPUs as well as 16 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the Radeon R9 M370X, which has core clock speeds of 800 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have the exact same memory bandwidth, so in theory they should perform exactly the same. (explain)
Texel RateThe Radeon R9 M370X should be quite a bit (about 158%) better at AF than the Radeon HD 3870 1GB. (explain)
Pixel RateThe Radeon R9 M370X should be a little bit (about 3%) better at AA than the Radeon HD 3870 1GB, and will be capable of handling higher resolutions without slowing down too much. (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 largest amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs 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 lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
