GeForce 8600 GS (OEM) vs GeForce 920M

Intro

The GeForce 8600 GS (OEM) features a GPU clock speed of 540 MHz, and the 256 MB of DDR2 memory is set to run at 400 MHz through a 128-bit bus. It also is comprised of 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.

Compare all of that to the GeForce 920M, which features core speeds of 954 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs along with 32 Texture Address Units and 8 ROPs.

GeForce 8600 GS (OEM) 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 920M will be much (about 253%) more effective at texture filtering than the GeForce 8600 GS (OEM). (explain)

GeForce 920M 30528 Mtexels/sec
GeForce 8600 GS (OEM) 8640 Mtexels/sec
Difference: 21888 (253%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 920M is superior to the GeForce 8600 GS (OEM), by far. (explain)

GeForce 920M 7632 Mpixels/sec
GeForce 8600 GS (OEM) 4320 Mpixels/sec
Difference: 3312 (77%)

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: Bandwidth is the max amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at 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 video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
