GeForce 8800 GT 1GB vs GeForce GTX 460 (OEM)

Intro

Compare those specifications to the GeForce GTX 460 (OEM), which uses a 40 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR5 memory is set to run at a frequency of 850 MHz on this particular card. It features 336 SPUs along with 56 TAUs and 32 Rasterization Operator Units.

Texel Rate

The GeForce GTX 460 (OEM) will be a small bit (about 8%) more effective at anisotropic filtering than the GeForce 8800 GT 1GB. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 2800 (8%)

Pixel Rate

If using 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 8800 GT 1GB		9600 Mpixels/sec
	Difference: 11200 (117%)

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 largest amount of information (measured in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, 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 most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
