Compare any two graphics cards:
GeForce GT 440 1.5GB vs Radeon R9 M380
IntroThe GeForce GT 440 1.5GB comes with a GPU core clock speed of 594 MHz, and the 1536 MB of GDDR3 RAM is set to run at 900 MHz through a 192-bit bus. It also is made up of 144 SPUs, 24 TAUs, and 24 ROPs.Compare those specs to the Radeon R9 M380, which has core speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon R9 M380 should theoretically be much better than the GeForce GT 440 1.5GB overall. (explain)
Texel RateThe Radeon R9 M380 is a lot (about 181%) more effective at AF than the GeForce GT 440 1.5GB. (explain)
Pixel RateThe Radeon R9 M380 will be a bit (about 12%) faster with regards to FSAA than the GeForce GT 440 1.5GB, and also should be able to handle higher resolutions better. (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 data (counted in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the 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 texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, 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 maximum amount of pixels the video card can possibly record to the 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 the core 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 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 ability to reach the maximum fill rate.
