GeForce 8600 GS (OEM) vs GeForce 920M

Intro

The GeForce 8600 GS (OEM) uses a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The DDR2 memory runs at a frequency of 400 MHz on this model. It features 32 SPUs along with 16 TAUs and 8 ROPs.

Compare those specifications to the GeForce 920M, which makes use of a 28 nm design. nVidia has set the core frequency at 954 MHz. The DDR3 RAM is set to run at a speed of 900 MHz on this particular model. It features 384 SPUs along with 32 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce 920M should perform a little bit faster than the GeForce 8600 GS (OEM) overall. (explain)

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

Texel Rate

The GeForce 920M will be quite a bit (approximately 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

The GeForce 920M will be quite a bit (about 77%) better at FSAA than the GeForce 8600 GS (OEM), and will be capable of handling higher screen resolutions without losing too much performance. (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 maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per 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 drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
