GeForce GT 220 GDDR3 vs GeForce GT 430 1GB

Intro

Compare all of that to the GeForce GT 430 1GB, which has core clock speeds of 700 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 memory. 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 1GB		60 Watts
	Difference: 2 Watts (3%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 220 GDDR3 should be 12% faster than the GeForce GT 430 1GB overall, because of its greater bandwidth. (explain)

GeForce GT 220 GDDR3		32384 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 3584 (12%)

Texel Rate

The GeForce GT 430 1GB should be just a bit (about 12%) better at 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

The GeForce GT 220 GDDR3 is quite a bit (approximately 79%) faster with regards to anti-aliasing than the GeForce GT 430 1GB, and also able to handle higher resolutions while still performing well. (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 maximum amount of information (in units of MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
