GeForce 8300 GS (OEM) vs GeForce GT 430 1GB

Intro

Compare all that to the GeForce GT 430 1GB, which has GPU clock speed of 700 MHz, and 1024 MB of GDDR3 RAM set to run at 900 MHz through a 128-bit bus. It also features 96 Stream Processors, 16 Texture Address Units, and 4 ROPs.

GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 9400 (522%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 430 1GB is superior to the GeForce 8300 GS (OEM), by far. (explain)

GeForce GT 430 1GB		2800 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 1900 (211%)

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 (counted in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics 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 amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
