GeForce 8600 GS (OEM) vs GeForce 920M

Intro

Compare that to the GeForce 920M, which uses a 28 nm design. nVidia has set the core frequency at 954 MHz. The DDR3 RAM works at a speed of 900 MHz on this particular card. It features 384 SPUs along with 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 920M should be 13% quicker than the GeForce 8600 GS (OEM) in general, due to its higher bandwidth. (explain)

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

Texel Rate

The GeForce 920M will be much (about 253%) better at anisotropic 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

The GeForce 920M is a lot (more or less 77%) more effective at FSAA than the GeForce 8600 GS (OEM), and also will be capable of handling higher screen resolutions better. (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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, 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 maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
