GeForce 8500 GT vs GeForce GTX 460 (OEM)

Intro

Compare all that to the GeForce GTX 460 (OEM), which uses a 40 nm design. nVidia has set the core frequency at 650 MHz. The GDDR5 RAM works at a frequency of 850 MHz on this particular card. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.

GeForce 8500 GT		12800 MB/sec
	Difference: 96000 (750%)

Texel Rate

The GeForce GTX 460 (OEM) should be quite a bit (approximately 911%) more effective at AF than the GeForce 8500 GT. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 32800 (911%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 (OEM) is the winner, and very much so. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 19000 (1056%)

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 maximum amount of data (in units of MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
