Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M365X should theoretically be quite a bit superior to the GeForce 8800 GT 512MB overall. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M365X is a little bit (more or less 10%) faster with regards to anisotropic filtering than the GeForce 8800 GT 512MB. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 3400 (10%)

Pixel Rate

The Radeon R9 M365X is much (about 54%) better at anti-aliasing than the GeForce 8800 GT 512MB, and capable of handling higher resolutions while still performing well. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 5200 (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 largest amount of information (counted in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per 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 worked out by multiplying the amount of Render Output Units by the the core clock speed. 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
