Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GTX is 20% quicker than the Radeon R9 M370X in general, because of its higher bandwidth. (explain)

GeForce 8800 GTX		86400 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce 8800 GTX is a small bit (more or less 15%) faster with regards to AF than the Radeon R9 M370X. (explain)

GeForce 8800 GTX		36800 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 4800 (15%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 8800 GTX is the winner, though only just barely. (explain)

GeForce 8800 GTX		13800 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 1000 (8%)

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 largest amount of information (counted in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must 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 texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, 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 most pixels that the graphics card could 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 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 rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
