Compare any two graphics cards:
Radeon HD 4670 512MB vs Radeon R9 M375
IntroThe Radeon HD 4670 512MB comes with clock speeds of 750 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR4/GDDR3/DDR3/DDR2 memory. It features 320(64x5) SPUs as well as 32 TAUs and 8 Rasterization Operator Units.Compare those specs to the Radeon R9 M375, which makes use of a 28 nm design. AMD has set the core speed at 1015 MHz. The DDR3 RAM works at a speed of 1100 MHz on this particular card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.
Display Graphs
Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon R9 M375 should perform just a bit faster than the Radeon HD 4670 512MB overall. (explain)
Texel RateThe Radeon R9 M375 should be much (about 69%) more effective at texture filtering than the Radeon HD 4670 512MB. (explain)
Pixel RateThe Radeon R9 M375 is much (approximately 171%) faster with regards to anti-aliasing than the Radeon HD 4670 512MB, and should be capable of handling higher screen resolutions more effectively. (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 data (in units of megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher 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 most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
