Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M365X, in theory, should perform quite a bit faster than the GeForce 8600 GT 1GB GDDR3 in general. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce 8600 GT 1GB GDDR3		22400 MB/sec
	Difference: 49600 (221%)

Texel Rate

The Radeon R9 M365X will be a lot (approximately 328%) faster with regards to AF than the GeForce 8600 GT 1GB GDDR3. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce 8600 GT 1GB GDDR3		8640 Mtexels/sec
	Difference: 28360 (328%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M365X is superior to the GeForce 8600 GT 1GB GDDR3, by a large margin. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce 8600 GT 1GB GDDR3		4320 Mpixels/sec
	Difference: 10480 (243%)

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 (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
