GeForce 8600 GT 512MB DDR2 vs GeForce GT 430 (OEM)

Intro

The GeForce 8600 GT 512MB DDR2 has a GPU core speed of 540 MHz, and the 512 MB of DDR2 memory runs at 400 MHz through a 128-bit bus. It also is comprised of 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specifications to the GeForce GT 430 (OEM), which has a clock frequency of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It features 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.

GeForce GT 430 (OEM) 28800 MB/sec
GeForce 8600 GT 512MB DDR2 12800 MB/sec
Difference: 16000 (125%)

Texel Rate

The GeForce GT 430 (OEM) should be a lot (approximately 30%) more effective at texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)

GeForce GT 430 (OEM) 11200 Mtexels/sec
GeForce 8600 GT 512MB DDR2 8640 Mtexels/sec
Difference: 2560 (30%)

Pixel Rate

The GeForce 8600 GT 512MB DDR2 should be a lot (approximately 54%) more effective at anti-aliasing than the GeForce GT 430 (OEM), and also will be able to handle higher screen resolutions while still performing well. (explain)

GeForce 8600 GT 512MB DDR2 4320 Mpixels/sec
GeForce GT 430 (OEM) 2800 Mpixels/sec
Difference: 1520 (54%)

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 maximum amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units of the card by the core clock 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 graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
