GeForce 8600 GS (OEM) vs GeForce 920M

Intro

The GeForce 8600 GS (OEM) features a clock frequency of 540 MHz and a DDR2 memory speed of 400 MHz. It also uses a 128-bit memory bus, and uses a 80 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare all of that to the GeForce 920M, which makes use of a 28 nm design. nVidia has clocked the core frequency at 954 MHz. The DDR3 memory runs at a speed of 900 MHz on this specific card. It features 384 SPUs as well as 32 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 920M should be just a 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 a lot (about 253%) better 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 the winner, 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.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure 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 also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
