Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M380 should theoretically be quite a bit superior to the GeForce 9600 GSO 1.5GB in general. (explain)

Radeon R9 M380		96000 MB/sec
GeForce 9600 GSO 1.5GB		38400 MB/sec
	Difference: 57600 (150%)

Texel Rate

The Radeon R9 M380 should be much (more or less 52%) faster with regards to anisotropic filtering than the GeForce 9600 GSO 1.5GB. (explain)

Radeon R9 M380		40000 Mtexels/sec
GeForce 9600 GSO 1.5GB		26400 Mtexels/sec
	Difference: 13600 (52%)

Pixel Rate

The Radeon R9 M380 should be a lot (approximately 142%) faster with regards to AA than the GeForce 9600 GSO 1.5GB, and also will be able to handle higher resolutions more effectively. (explain)

Radeon R9 M380		16000 Mpixels/sec
GeForce 9600 GSO 1.5GB		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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
