GeForce 8600 GS (OEM) vs GeForce 920M

Intro

Compare all that to the GeForce 920M, which features GPU clock speed of 954 MHz, and 2048 MB of DDR3 memory set to run at 900 MHz through a 64-bit bus. It also is comprised of 384 Stream Processors, 32 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 920M should theoretically be a little bit faster than the GeForce 8600 GS (OEM) in general. (explain)

GeForce 920M		14400 MB/sec
GeForce 8600 GS (OEM)		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The GeForce 920M should be quite a bit (about 253%) better at AF 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 using lots of anti-aliasing is important to you, then the GeForce 920M is superior to the GeForce 8600 GS (OEM), and very much so. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, 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 number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
