Compare any two graphics cards:
GeForce 8800 GT 256MB vs Radeon R9 M380
IntroThe GeForce 8800 GT 256MB makes use of a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 RAM is set to run at a frequency of 700 MHz on this model. It features 112 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.Compare all that to the Radeon R9 M380, which comes with 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 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the Radeon R9 M380 should be a lot faster than the GeForce 8800 GT 256MB in general. (explain)
Texel RateThe Radeon R9 M380 is a small bit (about 19%) faster with regards to anisotropic filtering than the GeForce 8800 GT 256MB. (explain)
Pixel RateThe Radeon R9 M380 should be quite a bit (about 67%) faster with regards to AA than the GeForce 8800 GT 256MB, and also capable of handling higher 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: Bandwidth is the maximum amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 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 reach the max fill rate.
