GeForce GT 320 vs GeForce GT 430 1GB

Intro

Compare all of that to the GeForce GT 430 1GB, which has core clock speeds of 700 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 memory. It features 96 SPUs along with 16 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
GeForce GT 430 1GB		60 Watts
	Difference: 17 Watts (40%)

Memory Bandwidth

In theory, the GeForce GT 430 1GB is 14% faster than the GeForce GT 320 overall, because of its higher data rate. (explain)

GeForce GT 430 1GB		28800 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 3520 (14%)

Texel Rate

The GeForce GT 320 should be a little bit (more or less 16%) faster with regards to texture filtering than the GeForce GT 430 1GB. (explain)

GeForce GT 320		12960 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 1760 (16%)

Pixel Rate

The GeForce GT 320 will be much (about 54%) better at FSAA than the GeForce GT 430 1GB, and will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GT 320		4320 Mpixels/sec
GeForce GT 430 1GB		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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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 reach the maximum fill rate.
