GeForce 8800 GTS (G92) vs GeForce GTX 460

Intro

Compare those specifications to the GeForce GTX 460, which makes use of a 40 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR5 memory is set to run at a frequency of 900 MHz on this particular model. It features 336 SPUs along with 56 TAUs and 24 Rasterization Operator Units.

GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 24320 (39%)

Texel Rate

The GeForce 8800 GTS (G92) will be a bit (more or less 10%) better at texture filtering than the GeForce GTX 460. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 3800 (10%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 460 is superior to the GeForce 8800 GTS (G92), and very much so. (explain)

GeForce GTX 460		16200 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 5800 (56%)

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 maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core 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 fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
