GeForce GTX 460 1GB vs Geforce GTX 670

Intro

Compare those specifications to the Geforce GTX 670, which comes with GPU clock speed of 915 MHz, and 2048 MB of GDDR5 RAM running at 1500 MHz through a 256-bit bus. It also is comprised of 1344 SPUs, 112 TAUs, and 32 ROPs.

GeForce GTX 460 1GB		115200 MB/sec
	Difference: 76800 (67%)

Texel Rate

The Geforce GTX 670 will be quite a bit (approximately 171%) more effective at anisotropic filtering than the GeForce GTX 460 1GB. (explain)

Geforce GTX 670		102480 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 64680 (171%)

Pixel Rate

If using a high resolution is important to you, then the Geforce GTX 670 is a better choice, by a large margin. (explain)

Geforce GTX 670		29280 Mpixels/sec
GeForce GTX 460 1GB		21600 Mpixels/sec
	Difference: 7680 (36%)

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 max amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
