Compare any two graphics cards:
Radeon HD 4770 vs Radeon R9 M375
IntroThe Radeon HD 4770 features a GPU core speed of 750 MHz, and the 512 MB of GDDR5 RAM runs at 800 MHz through a 128-bit bus. It also features 640(128x5) Stream Processors, 32 Texture Address Units, and 16 ROPs.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 uses a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 4770, in theory, should perform much faster than the Radeon R9 M375 in general. (explain)
Texel RateThe Radeon R9 M375 will be quite a bit (more or less 69%) more effective at AF than the Radeon HD 4770. (explain)
Pixel RateThe Radeon R9 M375 will be much (about 35%) more effective at FSAA than the Radeon HD 4770, and also will be able to handle higher screen resolutions without losing too much performance. (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 information (in units of megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out 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 applied in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
