Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M380, in theory, should be a lot faster than the GeForce GT 130 overall. (explain)

Radeon R9 M380		96000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 84000 (700%)

Texel Rate

The Radeon R9 M380 will be a lot (more or less 233%) faster with regards to anisotropic filtering than the GeForce GT 130. (explain)

Radeon R9 M380		40000 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 28000 (233%)

Pixel Rate

The Radeon R9 M380 should be much (about 100%) more effective at anti-aliasing than the GeForce GT 130, and also capable of handling higher resolutions better. (explain)

Radeon R9 M380		16000 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 8000 (100%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the 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 amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
