Compare any two graphics cards:
GeForce 820M vs Radeon R9 380X
IntroThe GeForce 820M has a GPU clock speed of 719 MHz, and the 2048 MB of DDR3 RAM is set to run at 1000 MHz through a 64-bit bus. It also features 96 Stream Processors, 16 Texture Address Units, and 4 Raster Operation Units.Compare all of that to the Radeon R9 380X, which has a core clock speed of 970 MHz and a GDDR5 memory frequency of 1425 MHz. It also makes use of a 256-bit bus, and uses a 28 nm design. It is made up of 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 380X should theoretically be a lot faster than the GeForce 820M in general. (explain)
Texel RateThe Radeon R9 380X will be quite a bit (approximately 979%) more effective at anisotropic filtering than the GeForce 820M. (explain)
Pixel RateThe Radeon R9 380X is much (more or less 979%) faster with regards to anti-aliasing than the GeForce 820M, and should be able to handle higher screen 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 max amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen 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 amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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.
