GeForce 9500 GT 1GB GDDR3 vs GeForce GT 430 1GB

Intro

The GeForce 9500 GT 1GB GDDR3 uses a 55 nm design. nVidia has set the core speed at 550 MHz. The GDDR3 memory runs at a frequency of 800 MHz on this particular model. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Compare those specs to the GeForce GT 430 1GB, which comes with GPU clock speed of 700 MHz, and 1024 MB of GDDR3 memory set to run at 900 MHz through a 128-bit bus. It also features 96 SPUs, 16 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 1GB GDDR3 50 Watts
GeForce GT 430 1GB 60 Watts
Difference: 10 Watts (20%)

Memory Bandwidth

In theory, the GeForce GT 430 1GB should be 13% quicker than the GeForce 9500 GT 1GB GDDR3 overall, because of its higher data rate. (explain)

GeForce GT 430 1GB 28800 MB/sec
GeForce 9500 GT 1GB GDDR3 25600 MB/sec
Difference: 3200 (13%)

Texel Rate

The GeForce GT 430 1GB should be much (approximately 27%) better at AF than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce GT 430 1GB 11200 Mtexels/sec
GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Difference: 2400 (27%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 9500 GT 1GB GDDR3 is superior to the GeForce GT 430 1GB, and very much so. (explain)

GeForce 9500 GT 1GB GDDR3 4400 Mpixels/sec
GeForce GT 430 1GB 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 information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 can be applied in one second. This number is calculated by multiplying the total 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
