GeForce 8800 GS vs GeForce GTX 860M

Intro

Compare that to the GeForce GTX 860M, which features a core clock speed of 797 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is comprised of 1152 SPUs, 96 TAUs, and 16 ROPs.

GeForce GTX 860M		45 Watts
GeForce 8800 GS		105 Watts
	Difference: 60 Watts (133%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 860M should perform a lot faster than the GeForce 8800 GS overall. (explain)

GeForce GTX 860M		64000 MB/sec
GeForce 8800 GS		38400 MB/sec
	Difference: 25600 (67%)

Texel Rate

The GeForce GTX 860M is quite a bit (more or less 190%) faster with regards to texture filtering than the GeForce 8800 GS. (explain)

GeForce GTX 860M		76512 Mtexels/sec
GeForce 8800 GS		26400 Mtexels/sec
	Difference: 50112 (190%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 860M is a better choice, by far. (explain)

GeForce GTX 860M		12752 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 6152 (93%)

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 max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 max fill rate.
