GeForce 8800 GT 512MB vs GeForce GTX 960M

Intro

Compare those specifications to the GeForce GTX 960M, which comes with a clock speed of 1096 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 960M		65 Watts
GeForce 8800 GT 512MB		105 Watts
	Difference: 40 Watts (62%)

Memory Bandwidth

Theoretically, the GeForce GTX 960M should be a small bit faster than the GeForce 8800 GT 512MB overall. (explain)

GeForce GTX 960M		64000 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The GeForce GTX 960M should be much (more or less 30%) more effective at AF than the GeForce 8800 GT 512MB. (explain)

GeForce GTX 960M		43840 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 10240 (30%)

Pixel Rate

The GeForce GTX 960M should be a lot (approximately 83%) faster with regards to FSAA than the GeForce 8800 GT 512MB, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 960M		17536 Mpixels/sec
GeForce 8800 GT 512MB		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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
