Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 9600 GSO 768MB should perform just a bit faster than the Radeon R9 M375 overall. (explain)

GeForce 9600 GSO 768MB		38400 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 3200 (9%)

Texel Rate

The Radeon R9 M375 is much (about 54%) more effective at anisotropic filtering than the GeForce 9600 GSO 768MB. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 14200 (54%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 M375 is the winner, by far. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 9640 (146%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
