GeForce 8800 GT 1GB vs GeForce GTX 860M

Intro

The GeForce 8800 GT 1GB has a GPU core clock speed of 600 MHz, and the 1024 MB of GDDR3 memory is set to run at 900 MHz through a 256-bit bus. It also is made up of 112 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

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

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

Texel Rate

The GeForce GTX 860M is a lot (about 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 resolution is important to you, then the GeForce GTX 860M is a better choice, and very much so. (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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
