GeForce 8300 GS (OEM) vs GeForce GT 430

Intro

Compare all of that to the GeForce GT 430, which has a core clock frequency of 700 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It features 96 SPUs, 16 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8300 GS (OEM)		40 Watts
GeForce GT 430		60 Watts
	Difference: 20 Watts (50%)

Memory Bandwidth

Performance-wise, the GeForce GT 430 should in theory be a lot better than the GeForce 8300 GS (OEM) in general. (explain)

GeForce GT 430		28800 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 22400 (350%)

Texel Rate

The GeForce GT 430 should be quite a bit (about 522%) more effective at AF 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 is much (more or less 211%) better at anti-aliasing than the GeForce 8300 GS (OEM), and also should be capable of handling higher 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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units 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 a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
