GeForce GT 220 GDDR3 vs GeForce GT 430 (OEM)

Intro

Compare those specifications to the GeForce GT 430 (OEM), which features a clock frequency of 700 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is made up of 96 SPUs, 16 Texture Address Units, and 4 ROPs.

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

Texel Rate

The GeForce GT 430 (OEM) will be a little bit (more or less 12%) better at texture filtering 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 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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
