GeForce GT 220 GDDR3 vs GeForce GT 430 1GB

Intro

Compare all of that to the GeForce GT 430 1GB, which uses a 40 nm design. nVidia has clocked the core frequency at 700 MHz. The GDDR3 memory runs at a speed of 900 MHz on this model. It features 96 SPUs as well as 16 TAUs and 4 ROPs.

GeForce GT 430 1GB		28800 MB/sec
	Difference: 3584 (12%)

Texel Rate

The GeForce GT 430 1GB is just a bit (approximately 12%) faster with regards to AF than the GeForce GT 220 GDDR3. (explain)

GeForce GT 430 1GB		11200 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 1200 (12%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 220 GDDR3 is superior to the GeForce GT 430 1GB, by far. (explain)

GeForce GT 220 GDDR3		5000 Mpixels/sec
GeForce GT 430 1GB		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 largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
