VS

GeForce 8600 GS (OEM) vs GeForce 930M

Intro

The GeForce 8600 GS (OEM) features clock speeds of 540 MHz on the GPU, and 400 MHz on the 256 MB of DDR2 RAM. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Compare that to the GeForce 930M, which uses a 28 nm design. nVidia has clocked the core speed at 928 MHz. The DDR3 memory works at a speed of 900 MHz on this particular card. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 930M, in theory, should be a bit faster than the GeForce 8600 GS (OEM) overall. (explain)

GeForce 930M 14400 MB/sec
GeForce 8600 GS (OEM) 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 930M will be a lot (about 158%) more effective at anisotropic filtering than the GeForce 8600 GS (OEM). (explain)

GeForce 930M 22272 Mtexels/sec
GeForce 8600 GS (OEM) 8640 Mtexels/sec
Difference: 13632 (158%)

Pixel Rate

The GeForce 930M is a lot (about 72%) better at full screen anti-aliasing than the GeForce 8600 GS (OEM), and capable of handling higher resolutions without slowing down too much. (explain)

GeForce 930M 7424 Mpixels/sec
GeForce 8600 GS (OEM) 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 data (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 interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 fill rate also depends on quite a few 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.
