Compare any two graphics cards:
Radeon HD 3870 512MB vs Radeon R9 M375X
IntroThe Radeon HD 3870 512MB features a core clock speed of 775 MHz and a GDDR3 memory speed of 900 MHz. It also features a 256-bit bus, and makes use of a 55 nm design. It is made up of 320(64x5) SPUs, 16 TAUs, and 16 ROPs.Compare that to the Radeon R9 M375X, which features GPU clock speed of 1015 MHz, and 4096 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R9 M375X should be 25% faster than the Radeon HD 3870 512MB in general, because of its higher data rate. (explain)
Texel RateThe Radeon R9 M375X is quite a bit (about 227%) more effective at texture filtering than the Radeon HD 3870 512MB. (explain)
Pixel RateThe Radeon R9 M375X will be quite a bit (approximately 31%) faster with regards to FSAA than the Radeon HD 3870 512MB, and should be capable of handling higher screen resolutions while still performing well. (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 maximum amount of information (measured in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR 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 anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
