GeForce 9500 GT 1GB GDDR3 vs GeForce GT 430

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 speed of 800 MHz on this specific model. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.

Compare those specs to the GeForce GT 430, which comes with 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 SPUs, 16 TAUs, and 4 Raster Operation Units.

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

Memory Bandwidth

As far as performance goes, the GeForce GT 430 should theoretically be a bit better than the GeForce 9500 GT 1GB GDDR3 in general. (explain)

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

Texel Rate

The GeForce GT 430 should be much (more or less 27%) better at anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the GeForce 9500 GT 1GB GDDR3 is the winner, by a large margin. (explain)

GeForce 9500 GT 1GB GDDR3 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 information (counted in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video 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 that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
