GeForce 8800 GTX vs GeForce GTX 460

Intro

The GeForce 8800 GTX has clock speeds of 575 MHz on the GPU, and 900 MHz on the 768 MB of GDDR3 RAM. It features 128 SPUs along with 64 TAUs and 24 Rasterization Operator Units.

Compare all that to the GeForce GTX 460, which features core speeds of 675 MHz on the GPU, and 900 MHz on the 768 MB of GDDR5 RAM. It features 336 SPUs as well as 56 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 460 150 Watts
GeForce 8800 GTX 155 Watts
Difference: 5 Watts (3%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The GeForce GTX 460 is a little bit (approximately 3%) more effective at texture filtering than the GeForce 8800 GTX. (explain)

GeForce GTX 460 37800 Mtexels/sec
GeForce 8800 GTX 36800 Mtexels/sec
Difference: 1000 (3%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 is a better choice, not by a very large margin though. (explain)

GeForce GTX 460 16200 Mpixels/sec
GeForce 8800 GTX 13800 Mpixels/sec
Difference: 2400 (17%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
