GeForce GT 130 vs GeForce GT 430

Intro

Compare those specifications to the GeForce GT 430, which features core clock speeds of 700 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 memory. It features 96 SPUs as well as 16 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430		60 Watts
GeForce GT 130		75 Watts
	Difference: 15 Watts (25%)

Memory Bandwidth

The GeForce GT 430 should in theory perform much faster than the GeForce GT 130 overall. (explain)

GeForce GT 430		28800 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 16800 (140%)

Texel Rate

The GeForce GT 130 will be a little bit (more or less 7%) faster with regards to anisotropic filtering than the GeForce GT 430. (explain)

GeForce GT 130		12000 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 800 (7%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GT 130 is a better choice, and very much so. (explain)

GeForce GT 130		8000 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 5200 (186%)

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: Bandwidth is the max amount of data (measured in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 number 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 the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
