Compare any two graphics cards:
Radeon HD 6450 (OEM) 1GB vs Radeon R9 M375X
IntroThe Radeon HD 6450 (OEM) 1GB comes with a core clock frequency of 750 MHz and a GDDR5 memory frequency of 900 MHz. It also features a 64-bit memory bus, and uses a 40 nm design. It is comprised of 160 SPUs, 8 TAUs, and 4 Raster Operation Units.Compare all that to the Radeon R9 M375X, which comes with a clock frequency of 1015 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the Radeon R9 M375X should be quite a bit faster than the Radeon HD 6450 (OEM) 1GB overall. (explain)
Texel RateThe Radeon R9 M375X is much (more or less 577%) more effective at texture filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R9 M375X is the winner, by far. (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 max amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core 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 is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
