Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M370X is 25% faster than the GeForce 8800 GT 1GB in general, because of its greater data rate. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The GeForce 8800 GT 1GB should be a little bit (approximately 5%) more effective at texture filtering than the Radeon R9 M370X. (explain)

GeForce 8800 GT 1GB		33600 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 1600 (5%)

Pixel Rate

The Radeon R9 M370X should be quite a bit (approximately 33%) faster with regards to anti-aliasing than the GeForce 8800 GT 1GB, and also capable of handling higher resolutions more effectively. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 3200 (33%)

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 data (measured in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
