GeForce 9800 GTX+ vs GeForce GT 430 1GB

Intro

Compare all of that to the GeForce GT 430 1GB, which comes with a core clock frequency of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is comprised of 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.

	Difference: 36032 (322%)

Pixel Rate

The GeForce 9800 GTX+ is quite a bit (about 322%) faster with regards to full screen anti-aliasing than the GeForce GT 430 1GB, and also should be capable of handling higher resolutions better. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
GeForce GT 430 1GB		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 max amount of information (in units of MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses 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 can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
