GeForce 830M vs GeForce 8600 GT 1GB DDR2

Intro

The GeForce 830M features a GPU core speed of 1029 MHz, and the 2048 MB of DDR3 RAM is set to run at 900 MHz through a 64-bit bus. It also features 256 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specifications to the GeForce 8600 GT 1GB DDR2, which uses a 80 nm design. nVidia has set the core frequency at 540 MHz. The DDR2 memory is set to run 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.

Memory Bandwidth

Theoretically speaking, the GeForce 830M should perform just a bit faster than the GeForce 8600 GT 1GB DDR2 in general. (explain)

GeForce 830M 14400 MB/sec
GeForce 8600 GT 1GB DDR2 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 830M should be a lot (about 91%) better at AF than the GeForce 8600 GT 1GB DDR2. (explain)

GeForce 830M 16464 Mtexels/sec
GeForce 8600 GT 1GB DDR2 8640 Mtexels/sec
Difference: 7824 (91%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 830M is a better choice, by a large margin. (explain)

GeForce 830M 8232 Mpixels/sec
GeForce 8600 GT 1GB DDR2 4320 Mpixels/sec
Difference: 3912 (91%)

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 transferred across the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture map elements (texels) that are applied in one 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 one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends 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.
