GeForce GT 220 GDDR3 vs GeForce GT 430 (OEM)

Intro

Compare those specifications to the GeForce GT 430 (OEM), which uses a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this card. It features 96 SPUs as well as 16 TAUs and 4 ROPs.

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

Memory Bandwidth

Theoretically, the GeForce GT 220 GDDR3 should perform a small bit faster than the GeForce GT 430 (OEM) overall. (explain)

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

Texel Rate

The GeForce GT 430 (OEM) is a little bit (about 12%) more effective at AF than the GeForce GT 220 GDDR3. (explain)

GeForce GT 430 (OEM)		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 the winner, and very much so. (explain)

GeForce GT 220 GDDR3		5000 Mpixels/sec
GeForce GT 430 (OEM)		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 information (in units of MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
