Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 960M		65 Watts
GeForce 8800 GT 1GB		105 Watts
	Difference: 40 Watts (62%)

Memory Bandwidth

In theory, the GeForce GTX 960M will be 11% quicker than the GeForce 8800 GT 1GB in general, because of its greater data rate. (explain)

GeForce GTX 960M		64000 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The GeForce GTX 960M should be much (more or less 30%) faster with regards to texture filtering than the GeForce 8800 GT 1GB. (explain)

GeForce GTX 960M		43840 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 10240 (30%)

Pixel Rate

The GeForce GTX 960M will be a lot (more or less 83%) better at anti-aliasing than the GeForce 8800 GT 1GB, and also will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 960M		17536 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 7936 (83%)

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 max amount of data (measured in MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
