GeForce GT 130 vs GeForce GT 430

Intro

Compare that to the GeForce GT 430, which uses a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this model. It features 96 SPUs as well as 16 Texture Address Units and 4 Rasterization Operator Units.

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

Memory Bandwidth

Theoretically speaking, the GeForce GT 430 is 140% faster than the GeForce GT 130 in general, because of its higher data rate. (explain)

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

Texel Rate

The GeForce GT 130 is a small bit (about 7%) better at 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 using a high resolution is important to you, then the GeForce GT 130 is superior to the GeForce GT 430, by far. (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: Memory bandwidth is the max amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video 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 - aka 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 - the lower the bandwidth is, the lower the ability to get to the max fill rate.
