GeForce 8800 GS vs GeForce GTX 460 (OEM)

Intro

Compare all of that to the GeForce GTX 460 (OEM), which has core speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.

GeForce 8800 GS		38400 MB/sec
	Difference: 70400 (183%)

Texel Rate

The GeForce GTX 460 (OEM) should be quite a bit (more or less 38%) faster with regards to anisotropic filtering than the GeForce 8800 GS. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
GeForce 8800 GS		26400 Mtexels/sec
	Difference: 10000 (38%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 460 (OEM) is a better choice, and very much so. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 14200 (215%)

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 (in units of MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at 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 video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
