Compare any two graphics cards:
Radeon HD 3870 1GB vs Radeon R9 M375
IntroThe Radeon HD 3870 1GB uses a 55 nm design. AMD has clocked the core frequency at 775 MHz. The GDDR4 memory runs at a frequency of 1125 MHz on this specific model. It features 320(64x5) SPUs along with 16 TAUs and 16 Rasterization Operator Units.Compare that to the Radeon R9 M375, which has a core clock frequency of 1015 MHz and a DDR3 memory speed of 1100 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon HD 3870 1GB is 105% quicker than the Radeon R9 M375 overall, because of its higher data rate. (explain)
Texel RateThe Radeon R9 M375 will be a lot (more or less 227%) more effective at AF than the Radeon HD 3870 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon R9 M375 is superior to the Radeon HD 3870 1GB, and very much so. (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 (measured in MB per second) that can be moved 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, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
