Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M385X should theoretically be much faster than the GeForce 8800 GT 1GB in general. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 38400 (67%)

Texel Rate

The Radeon R9 M385X will be quite a bit (about 83%) better at anisotropic filtering than the GeForce 8800 GT 1GB. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 28000 (83%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 M385X is a better choice, and very much so. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 8000 (83%)

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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher 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 the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 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.
