Compare any two graphics cards:
Radeon HD 4830 1GB vs Radeon R9 M375X
IntroThe Radeon HD 4830 1GB comes with a GPU core speed of 575 MHz, and the 1024 MB of GDDR4 memory is set to run at 900 MHz through a 256-bit bus. It also features 640(128x5) SPUs, 32 TAUs, and 16 Raster Operation Units.Compare those specifications to the Radeon R9 M375X, which comes with a GPU core clock speed of 1015 MHz, and 4096 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R9 M375X should in theory be a lot faster than the Radeon HD 4830 1GB in general. (explain)
Texel RateThe Radeon R9 M375X is quite a bit (more or less 121%) faster with regards to anisotropic filtering than the Radeon HD 4830 1GB. (explain)
Pixel RateThe Radeon R9 M375X is much (approximately 77%) better at AA than the Radeon HD 4830 1GB, and should be able to handle 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 maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses 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 high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics 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 maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
