GeForce 9800 GTX+ vs GeForce GT 430 (OEM)

Intro

Compare all that to the GeForce GT 430 (OEM), which has a GPU core clock speed of 700 MHz, and 2048 MB of GDDR3 RAM set to run at 900 MHz through a 128-bit bus. It also is made up of 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.

GeForce 9800 GTX+		145 Watts
	Difference: 85 Watts (142%)

Memory Bandwidth

Theoretically speaking, the GeForce 9800 GTX+ should be 144% faster than the GeForce GT 430 (OEM) in general, because of its higher data rate. (explain)

GeForce 9800 GTX+		70400 MB/sec
GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 41600 (144%)

Texel Rate

The GeForce 9800 GTX+ will be much (more or less 322%) faster with regards to texture filtering than the GeForce GT 430 (OEM). (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 36032 (322%)

Pixel Rate

The GeForce 9800 GTX+ is a lot (about 322%) more effective at anti-aliasing than the GeForce GT 430 (OEM), and capable of handling higher screen resolutions while still performing well. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 9008 (322%)

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 largest amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core clock 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. 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 lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
