GeForce GT 130 vs GeForce GT 430 1GB

Intro

Compare all 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 as well as 16 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430 1GB		60 Watts
GeForce GT 130		75 Watts
	Difference: 15 Watts (25%)

Memory Bandwidth

Theoretically, the GeForce GT 430 1GB should perform quite a bit faster than the GeForce GT 130 overall. (explain)

GeForce GT 430 1GB		28800 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 16800 (140%)

Texel Rate

The GeForce GT 130 is just a bit (about 7%) better at texture filtering than the GeForce GT 430 1GB. (explain)

GeForce GT 130		12000 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 800 (7%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 130 is superior to the GeForce GT 430 1GB, and very much so. (explain)

GeForce GT 130		8000 Mpixels/sec
GeForce GT 430 1GB		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 maximum amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video 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 amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many 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.
