GeForce 8800 GT 1GB vs GeForce GTX 860M

Intro

Compare those specifications to the GeForce GTX 860M, which uses a 28 nm design. nVidia has set the core frequency at 797 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this card. It features 1152 SPUs as well as 96 TAUs and 16 ROPs.

GeForce GTX 860M		45 Watts
GeForce 8800 GT 1GB		105 Watts
	Difference: 60 Watts (133%)

Memory Bandwidth

The GeForce GTX 860M, in theory, should be a little bit faster than the GeForce 8800 GT 1GB in general. (explain)

GeForce GTX 860M		64000 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The GeForce GTX 860M is quite a bit (approximately 128%) more effective at anisotropic filtering than the GeForce 8800 GT 1GB. (explain)

GeForce GTX 860M		76512 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 42912 (128%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 860M is the winner, by a large margin. (explain)

GeForce GTX 860M		12752 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 3152 (33%)

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 (counted in MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 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 better the texel rate, the better the video card will be at handling 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 the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
