GeForce GT 230 vs GeForce GT 430 1GB

Intro

Compare those specs to the GeForce GT 430 1GB, which makes use of a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this specific model. It features 96 SPUs along with 16 Texture Address Units and 4 Rasterization Operator Units.

GeForce GT 430 1GB		60 Watts
GeForce GT 230		65 Watts
	Difference: 5 Watts (8%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 230 is 33% quicker than the GeForce GT 430 1GB overall, due to its higher bandwidth. (explain)

GeForce GT 230		38400 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 9600 (33%)

Texel Rate

The GeForce GT 430 1GB is quite a bit (more or less 27%) faster with regards to texture filtering than the GeForce GT 230. (explain)

GeForce GT 430 1GB		11200 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 2400 (27%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GT 230 is the winner, by far. (explain)

GeForce GT 230		4400 Mpixels/sec
GeForce GT 430 1GB		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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
