GeForce GT 220 GDDR3 vs GeForce GT 430 1GB

Intro

Compare that to the GeForce GT 430 1GB, which comes with GPU core speed of 700 MHz, and 1024 MB of GDDR3 memory set to run at 900 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 16 TAUs, and 4 ROPs.

Texel Rate

The GeForce GT 430 1GB will be a bit (about 12%) faster with regards to texture filtering 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 lots of anti-aliasing 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 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: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units 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 in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
