GeForce 8600 GT 512MB DDR2 vs GeForce 930M

Intro

The GeForce 8600 GT 512MB DDR2 uses a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The DDR2 memory runs at a speed of 400 MHz on this specific card. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.

Compare all of that to the GeForce 930M, which features GPU clock speed of 928 MHz, and 2048 MB of DDR3 memory running at 900 MHz through a 64-bit bus. It also is made up of 384 Stream Processors, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 930M should in theory be a bit superior to the GeForce 8600 GT 512MB DDR2 overall. (explain)

GeForce 930M 14400 MB/sec
GeForce 8600 GT 512MB DDR2 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 930M will be a lot (about 158%) better at texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)

GeForce 930M 22272 Mtexels/sec
GeForce 8600 GT 512MB DDR2 8640 Mtexels/sec
Difference: 13632 (158%)

Pixel Rate

If using a high resolution is important to you, then the GeForce 930M is the winner, by far. (explain)

GeForce 930M 7424 Mpixels/sec
GeForce 8600 GT 512MB 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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
