Compare any two graphics cards:
Radeon HD 3850 1GB vs Radeon R9 M375
IntroThe Radeon HD 3850 1GB features a core clock speed of 668 MHz and a GDDR3 memory frequency of 828 MHz. It also makes use of a 256-bit memory bus, and makes use of a 55 nm design. It is comprised of 320(64x5) SPUs, 16 TAUs, and 16 ROPs.Compare that to the Radeon R9 M375, which comes with clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon HD 3850 1GB should be 51% quicker than the Radeon R9 M375 in general, due to its greater bandwidth. (explain)
Texel RateThe Radeon R9 M375 should be quite a bit (about 280%) better at anisotropic filtering than the Radeon HD 3850 1GB. (explain)
Pixel RateThe Radeon R9 M375 should be a lot (about 52%) more effective at full screen anti-aliasing than the Radeon HD 3850 1GB, and 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: Bandwidth is the max amount of information (counted in MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
