GeForce 9500 GT DDR2 vs GeForce GT 430

Intro

The GeForce 9500 GT DDR2 comes with a core clock speed of 550 MHz and a DDR2 memory speed of 500 MHz. It also makes use of a 128-bit memory bus, and uses a 65 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 ROPs.

Compare those specifications to the GeForce GT 430, which has GPU clock speed of 700 MHz, and 512 MB of GDDR3 RAM set to run at 900 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 16 Texture Address Units, and 4 Raster Operation Units.

GeForce 9500 GT DDR2 16000 MB/sec
Difference: 12800 (80%)

Texel Rate

The GeForce GT 430 is quite a bit (approximately 27%) faster with regards to anisotropic filtering than the GeForce 9500 GT DDR2. (explain)

GeForce GT 430 11200 Mtexels/sec
GeForce 9500 GT DDR2 8800 Mtexels/sec
Difference: 2400 (27%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 9500 GT DDR2 is a better choice, by far. (explain)

GeForce 9500 GT DDR2 4400 Mpixels/sec
GeForce GT 430 2800 Mpixels/sec
Difference: 1600 (57%)

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 data (counted in MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at 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 graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
