GeForce GT 230 vs GeForce GT 430

Intro

Compare all of that to the GeForce GT 430, which makes use of a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 memory runs 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.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce GT 230 will be 33% quicker than the GeForce GT 430 overall, due to its higher bandwidth. (explain)

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

Texel Rate

The GeForce GT 430 will be a lot (approximately 27%) faster with regards to texture filtering than the GeForce GT 230. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the GeForce GT 230 is the winner, and very much so. (explain)

GeForce GT 230		4400 Mpixels/sec
GeForce GT 430		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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 are applied in one second. This is worked out by multiplying the total texture units of the card by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
