GeForce 8800 GS vs GeForce GTX 460 (OEM)

Intro

Compare all that to the GeForce GTX 460 (OEM), which features GPU core speed of 650 MHz, and 1024 MB of GDDR5 memory running at 850 MHz through a 256-bit bus. It also is made up of 336 SPUs, 56 TAUs, and 32 ROPs.

	Difference: 45 Watts (43%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 (OEM) is 183% quicker than the GeForce 8800 GS in general, because of its greater bandwidth. (explain)

GeForce GTX 460 (OEM)		108800 MB/sec
GeForce 8800 GS		38400 MB/sec
	Difference: 70400 (183%)

Texel Rate

The GeForce GTX 460 (OEM) is quite a bit (about 38%) better at texture 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 running with lots of anti-aliasing is important to you, then the GeForce GTX 460 (OEM) is the winner, by a large margin. (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 maximum amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the 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 maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
