Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M380 is 55% quicker than the GeForce 8800 GTS (G92) in general, because of its greater data rate. (explain)

Radeon R9 M380		96000 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 33920 (55%)

Texel Rate

The GeForce 8800 GTS (G92) is just a bit (about 4%) more effective at texture filtering than the Radeon R9 M380. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 1600 (4%)

Pixel Rate

The Radeon R9 M380 is quite a bit (about 54%) better at AA than the GeForce 8800 GTS (G92), and able to handle higher resolutions while still performing well. (explain)

Radeon R9 M380		16000 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 5600 (54%)

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 data (counted in megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
