GeForce GTX 460 (OEM) vs Geforce GTX 670

Intro

Compare all that to the Geforce GTX 670, which features a clock speed of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 256-bit memory bus, and makes use of a 28 nm design. It features 1344 SPUs, 112 TAUs, and 32 Raster Operation Units.

GeForce GTX 460 (OEM)		150 Watts
Geforce GTX 670		170 Watts
	Difference: 20 Watts (13%)

Memory Bandwidth

In theory, the Geforce GTX 670 is 76% faster than the GeForce GTX 460 (OEM) in general, because of its higher bandwidth. (explain)

Geforce GTX 670		192000 MB/sec
GeForce GTX 460 (OEM)		108800 MB/sec
	Difference: 83200 (76%)

Texel Rate

The Geforce GTX 670 is a lot (more or less 182%) better at anisotropic filtering than the GeForce GTX 460 (OEM). (explain)

Geforce GTX 670		102480 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 66080 (182%)

Pixel Rate

The Geforce GTX 670 should be quite a bit (more or less 41%) faster with regards to FSAA than the GeForce GTX 460 (OEM), and able to handle higher screen resolutions better. (explain)

Geforce GTX 670		29280 Mpixels/sec
GeForce GTX 460 (OEM)		20800 Mpixels/sec
	Difference: 8480 (41%)

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 largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
