GeForce 8600 GT 1GB DDR2 vs GeForce GT 430 (OEM)

Intro

The GeForce 8600 GT 1GB DDR2 has a clock frequency of 540 MHz and a DDR2 memory frequency of 400 MHz. It also makes use of a 128-bit memory bus, and uses a 80 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specifications to the GeForce GT 430 (OEM), which comes with a core clock speed of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is comprised of 96 SPUs, 16 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 1GB DDR2 47 Watts
GeForce GT 430 (OEM) 60 Watts
Difference: 13 Watts (28%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 430 (OEM) should be 125% faster than the GeForce 8600 GT 1GB DDR2 in general, because of its higher bandwidth. (explain)

GeForce GT 430 (OEM) 28800 MB/sec
GeForce 8600 GT 1GB DDR2 12800 MB/sec
Difference: 16000 (125%)

Texel Rate

The GeForce GT 430 (OEM) will be quite a bit (about 30%) more effective at anisotropic filtering than the GeForce 8600 GT 1GB DDR2. (explain)

GeForce GT 430 (OEM) 11200 Mtexels/sec
GeForce 8600 GT 1GB DDR2 8640 Mtexels/sec
Difference: 2560 (30%)

Pixel Rate

The GeForce 8600 GT 1GB DDR2 should be much (about 54%) better at AA than the GeForce GT 430 (OEM), and also will be able to handle higher screen resolutions while still performing well. (explain)

GeForce 8600 GT 1GB 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 largest amount of data (measured in MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 get to the max fill rate.
