GeForce 8800 GT 1GB vs GeForce GTX 460

Intro

Compare that to the GeForce GTX 460, which makes use of a 40 nm design. nVidia has set the core frequency at 675 MHz. The GDDR5 memory runs at a frequency of 900 MHz on this particular model. It features 336 SPUs as well as 56 TAUs and 24 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 1GB		105 Watts
GeForce GTX 460		150 Watts
	Difference: 45 Watts (43%)

Memory Bandwidth

Theoretically, the GeForce GTX 460 should be much faster than the GeForce 8800 GT 1GB in general. (explain)

GeForce GTX 460		86400 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 28800 (50%)

Texel Rate

The GeForce GTX 460 should be a bit (more or less 13%) more effective at anisotropic filtering than the GeForce 8800 GT 1GB. (explain)

GeForce GTX 460		37800 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 4200 (13%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 is a better choice, and very much so. (explain)

GeForce GTX 460		16200 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 6600 (69%)

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 max amount of data (counted in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 processed per second. This figure is calculated 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its 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 - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
