GeForce 8800 GTX vs GeForce GTX 960M

Intro

Compare those specs to the GeForce GTX 960M, which has GPU clock speed of 1096 MHz, and 2048 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

GeForce GTX 960M		64000 MB/sec
	Difference: 22400 (35%)

Texel Rate

The GeForce GTX 960M should be a little bit (more or less 19%) more effective at AF than the GeForce 8800 GTX. (explain)

GeForce GTX 960M		43840 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 7040 (19%)

Pixel Rate

The GeForce GTX 960M should be a lot (approximately 27%) more effective at FSAA than the GeForce 8800 GTX, and will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 960M		17536 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 3736 (27%)

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 maximum amount of data (in units of MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses 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 can be processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
