Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375 is 175% faster than the GeForce 8600 GT 512MB DDR2 overall, due to its greater bandwidth. (explain)

Radeon R9 M375		35200 MB/sec
GeForce 8600 GT 512MB DDR2		12800 MB/sec
	Difference: 22400 (175%)

Texel Rate

The Radeon R9 M375 will be much (more or less 370%) faster with regards to anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 31960 (370%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M375 is superior to the GeForce 8600 GT 512MB DDR2, and very much so. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 11920 (276%)

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 max amount of information (measured in MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, the result 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
