GeForce 8800 GT 512MB vs GeForce GT 430 (OEM)

Intro

Compare those specifications to the GeForce GT 430 (OEM), which has a clock speed of 700 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.

GeForce 8800 GT 512MB		105 Watts
	Difference: 45 Watts (75%)

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GT 512MB should be 100% faster than the GeForce GT 430 (OEM) overall, due to its greater data rate. (explain)

GeForce 8800 GT 512MB		57600 MB/sec
GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 28800 (100%)

Texel Rate

The GeForce 8800 GT 512MB should be much (approximately 200%) better at AF than the GeForce GT 430 (OEM). (explain)

GeForce 8800 GT 512MB		33600 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 22400 (200%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 8800 GT 512MB is the winner, by far. (explain)

GeForce 8800 GT 512MB		9600 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 6800 (243%)

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 information (counted in MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure 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 outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
