GeForce 8600 GT 512MB DDR2 vs GeForce 920M

Intro

The GeForce 8600 GT 512MB DDR2 uses a 80 nm design. nVidia has set the core speed at 540 MHz. The DDR2 memory works at a speed of 400 MHz on this specific model. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Compare that to the GeForce 920M, which features GPU clock speed of 954 MHz, and 2048 MB of DDR3 RAM running at 900 MHz through a 64-bit bus. It also is made up of 384 SPUs, 32 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 920M is 13% faster than the GeForce 8600 GT 512MB DDR2 overall, due to its higher data rate. (explain)

GeForce 920M 14400 MB/sec
GeForce 8600 GT 512MB DDR2 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 920M should be a lot (approximately 253%) more effective at texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)

GeForce 920M 30528 Mtexels/sec
GeForce 8600 GT 512MB DDR2 8640 Mtexels/sec
Difference: 21888 (253%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 920M is a better choice, by a large margin. (explain)

GeForce 920M 7632 Mpixels/sec
GeForce 8600 GT 512MB DDR2 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 (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 are applied per second. This is worked out by multiplying the total texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
