GeForce 9800 GTX+ vs GeForce GT 430

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430		60 Watts
GeForce 9800 GTX+		145 Watts
	Difference: 85 Watts (142%)

Memory Bandwidth

Theoretically speaking, the GeForce 9800 GTX+ will be 144% quicker than the GeForce GT 430 overall, because of its higher bandwidth. (explain)

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

Texel Rate

The GeForce 9800 GTX+ will be a lot (more or less 322%) better at AF than the GeForce GT 430. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 9800 GTX+ is the winner, and very much so. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
GeForce GT 430		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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must 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 AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
