GeForce GT 220 GDDR3 vs GeForce GT 430

Intro

The GeForce GT 220 GDDR3 features a core clock speed of 625 MHz and a GDDR3 memory speed of 1012 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 48 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the GeForce GT 430, which uses a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR3 RAM works at a speed of 900 MHz on this particular card. It features 96 SPUs as well as 16 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GT 220 GDDR3 should perform a bit faster than the GeForce GT 430 in general. (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 just a bit (approximately 12%) faster with regards to AF 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 running with high levels of AA is important to you, then the GeForce GT 220 GDDR3 is a better choice, and very much so. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant 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 maximum fill rate.
