GeForce 9800 GTX+ vs GeForce GT 430

Intro

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

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

In theory, the GeForce 9800 GTX+ is 144% faster than the GeForce GT 430 in general, because of its greater 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 quite a bit (approximately 322%) more effective at texture filtering 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 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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's 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 - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
