GeForce 8800 Ultra vs GeForce GT 430 (OEM)

Intro

Compare all of that to the GeForce GT 430 (OEM), which features a clock speed 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 made up of 96 SPUs, 16 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430 (OEM)		60 Watts
GeForce 8800 Ultra		171 Watts
	Difference: 111 Watts (185%)

Memory Bandwidth

Theoretically speaking, the GeForce 8800 Ultra will be 260% faster than the GeForce GT 430 (OEM) in general, due to its higher data rate. (explain)

GeForce 8800 Ultra		103680 MB/sec
GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 74880 (260%)

Texel Rate

The GeForce 8800 Ultra should be quite a bit (approximately 250%) better at anisotropic filtering than the GeForce GT 430 (OEM). (explain)

GeForce 8800 Ultra		39168 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 27968 (250%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 8800 Ultra is superior to the GeForce GT 430 (OEM), and very much so. (explain)

GeForce 8800 Ultra		14688 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 11888 (425%)

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 largest amount of information (in units of MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
