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 memory runs at a speed of 1000 MHz on this specific card. It features 1152 SPUs along with 96 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 860M is 11% faster than the GeForce 8800 GT 1GB overall, because of its higher bandwidth. (explain)

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

Texel Rate

The GeForce GTX 860M should be quite a bit (more or less 128%) more effective at AF 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

The GeForce GTX 860M should be quite a bit (about 33%) better at AA than the GeForce 8800 GT 1GB, and should be capable of handling higher screen resolutions while still performing well. (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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at 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 per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
