Radeon R9 M395X		125 Watts
	Difference: 20 Watts (19%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 M395X should be 178% quicker than the GeForce 8800 GT 512MB in general, because of its higher bandwidth. (explain)

Radeon R9 M395X		160000 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 102400 (178%)

Texel Rate

The Radeon R9 M395X is a lot (more or less 175%) better at anisotropic filtering than the GeForce 8800 GT 512MB. (explain)

Radeon R9 M395X		92544 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 58944 (175%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M395X is superior to the GeForce 8800 GT 512MB, by a large margin. (explain)

Radeon R9 M395X		23136 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 13536 (141%)

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 max amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 per second. This number is worked out by multiplying the total number of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
