GeForce 8500 GT vs GeForce GT 430 (OEM)

Intro

Compare all of that to the GeForce GT 430 (OEM), which makes use of a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this particular card. It features 96 SPUs as well as 16 Texture Address Units and 4 Rasterization Operator Units.

GeForce 8500 GT		12800 MB/sec
	Difference: 16000 (125%)

Texel Rate

The GeForce GT 430 (OEM) is much (about 211%) faster with regards to anisotropic filtering than the GeForce 8500 GT. (explain)

GeForce GT 430 (OEM)		11200 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 7600 (211%)

Pixel Rate

The GeForce GT 430 (OEM) should be quite a bit (approximately 56%) faster with regards to AA than the GeForce 8500 GT, and will be capable of handling higher screen resolutions more effectively. (explain)

GeForce GT 430 (OEM)		2800 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 1000 (56%)

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 maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 per second. This is calculated by multiplying the total amount of texture units by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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 of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
