GeForce 8600 GT 256MB DDR2 vs GeForce 930M

Intro

The GeForce 8600 GT 256MB DDR2 uses a 80 nm design. nVidia has set the core frequency at 540 MHz. The DDR2 memory works at a frequency of 400 MHz on this card. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Compare all of that to the GeForce 930M, which comes with core clock speeds of 928 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 930M should be a small bit faster than the GeForce 8600 GT 256MB DDR2 in general. (explain)

GeForce 930M 14400 MB/sec
GeForce 8600 GT 256MB DDR2 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 930M should be a lot (more or less 158%) faster with regards to texture filtering than the GeForce 8600 GT 256MB DDR2. (explain)

GeForce 930M 22272 Mtexels/sec
GeForce 8600 GT 256MB DDR2 8640 Mtexels/sec
Difference: 13632 (158%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 930M is superior to the GeForce 8600 GT 256MB DDR2, by a large margin. (explain)

GeForce 930M 7424 Mpixels/sec
GeForce 8600 GT 256MB DDR2 4320 Mpixels/sec
Difference: 3104 (72%)

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 (in units of MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video 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 amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
