GeForce 9800 GT 1GB vs GeForce GT 430

Intro

Compare all of that to the GeForce GT 430, which uses a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this specific card. It features 96 SPUs along with 16 TAUs and 4 ROPs.

GeForce GT 430		28800 MB/sec
	Difference: 28800 (100%)

Texel Rate

The GeForce 9800 GT 1GB will be quite a bit (about 200%) faster with regards to anisotropic filtering than the GeForce GT 430. (explain)

GeForce 9800 GT 1GB		33600 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 22400 (200%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 9800 GT 1GB is superior to the GeForce GT 430, and very much so. (explain)

GeForce 9800 GT 1GB		9600 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 6800 (243%)

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 information (measured in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
