GeForce 8300 GS (OEM) vs GeForce GT 430

Intro

Compare those specifications to the GeForce GT 430, which comes with GPU clock speed of 700 MHz, and 512 MB of GDDR3 memory set to run at 900 MHz through a 128-bit bus. It also is made up of 96 SPUs, 16 TAUs, and 4 ROPs.

GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 22400 (350%)

Texel Rate

The GeForce GT 430 will be quite a bit (more or less 522%) better at anisotropic filtering than the GeForce 8300 GS (OEM). (explain)

GeForce GT 430		11200 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 9400 (522%)

Pixel Rate

The GeForce GT 430 will be a lot (more or less 211%) better at full screen anti-aliasing than the GeForce 8300 GS (OEM), and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GT 430		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 largest amount of information (measured in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the 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 that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few 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.
