Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M380 is 150% quicker than the GeForce 9600 GSO 768MB in general, because of its higher data rate. (explain)

Radeon R9 M380		96000 MB/sec
GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 57600 (150%)

Texel Rate

The Radeon R9 M380 is a lot (about 52%) faster with regards to AF than the GeForce 9600 GSO 768MB. (explain)

Radeon R9 M380		40000 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 13600 (52%)

Pixel Rate

The Radeon R9 M380 will be much (approximately 142%) more effective at full screen anti-aliasing than the GeForce 9600 GSO 768MB, and also able to handle higher screen resolutions more effectively. (explain)

Radeon R9 M380		16000 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 9400 (142%)

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 data (counted in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
