GeForce GT 230 vs GeForce GT 430

Intro

Compare all that to the GeForce GT 430, which features a clock frequency of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is made up of 96 SPUs, 16 TAUs, and 4 Raster Operation 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

Theoretically speaking, the GeForce GT 230 should be quite a bit faster than the GeForce GT 430 in general. (explain)

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

Texel Rate

The GeForce GT 430 should be a lot (about 27%) faster with regards to AF than the GeForce GT 230. (explain)

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

Pixel Rate

The GeForce GT 230 should be a lot (more or less 57%) faster with regards to full screen anti-aliasing than the GeForce GT 430, and also capable of handling higher resolutions without losing too much performance. (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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 can be processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
