GeForce GTX 460 1GB vs Geforce GTX 670

Intro

Compare all of that to the Geforce GTX 670, which has GPU core speed of 915 MHz, and 2048 MB of GDDR5 RAM set to run at 1500 MHz through a 256-bit bus. It also is made up of 1344 SPUs, 112 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 460 1GB		160 Watts
Geforce GTX 670		170 Watts
	Difference: 10 Watts (6%)

Memory Bandwidth

In theory, the Geforce GTX 670 should be quite a bit faster than the GeForce GTX 460 1GB overall. (explain)

Geforce GTX 670		192000 MB/sec
GeForce GTX 460 1GB		115200 MB/sec
	Difference: 76800 (67%)

Texel Rate

The Geforce GTX 670 is a lot (more or less 171%) more effective at AF 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 lots of anti-aliasing is important to you, then the Geforce GTX 670 is the winner, 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 information (in units of megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
