GeForce GT 220 GDDR3 vs GeForce GT 430

Intro

Compare those specs to the GeForce GT 430, which has clock speeds of 700 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 memory. It features 96 SPUs along with 16 TAUs and 4 ROPs.

GeForce GT 220 GDDR3		58 Watts
GeForce GT 430		60 Watts
	Difference: 2 Watts (3%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 220 GDDR3 will be 12% quicker than the GeForce GT 430 in general, due to its higher bandwidth. (explain)

GeForce GT 220 GDDR3		32384 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 3584 (12%)

Texel Rate

The GeForce GT 430 will be a small bit (about 12%) faster with regards to anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

GeForce GT 430		11200 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 1200 (12%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GT 220 GDDR3 is a better choice, by a large margin. (explain)

GeForce GT 220 GDDR3		5000 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 2200 (79%)

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 (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock 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 also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
