GeForce 8800 GTS (G92) vs GeForce GTX 460 (OEM)

Intro

Compare all of that to the GeForce GTX 460 (OEM), which uses a 40 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR5 RAM is set to run at a frequency of 850 MHz on this specific model. It features 336 SPUs along with 56 Texture Address Units and 32 Rasterization Operator Units.

	Difference: 46720 (75%)

Texel Rate

The GeForce 8800 GTS (G92) will be a bit (approximately 14%) more effective at AF than the GeForce GTX 460 (OEM). (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 5200 (14%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 460 (OEM) is a better choice, by far. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 10400 (100%)

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 (counted in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs 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 also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
