GeForce GTX 460 (OEM) vs GeForce GTX 470

Intro

Compare all of that to the GeForce GTX 470, which features clock speeds of 607 MHz on the GPU, and 837 MHz on the 1280 MB of GDDR5 RAM. It features 448 SPUs along with 56 Texture Address Units and 40 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 460 (OEM)		150 Watts
GeForce GTX 470		215 Watts
	Difference: 65 Watts (43%)

Memory Bandwidth

In theory, the GeForce GTX 470 should be quite a bit faster than the GeForce GTX 460 (OEM) in general. (explain)

GeForce GTX 470		133920 MB/sec
GeForce GTX 460 (OEM)		108800 MB/sec
	Difference: 25120 (23%)

Texel Rate

The GeForce GTX 460 (OEM) will be a small bit (about 7%) more effective at anisotropic filtering than the GeForce GTX 470. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
GeForce GTX 470		33992 Mtexels/sec
	Difference: 2408 (7%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 470 is a better choice, though only just barely. (explain)

GeForce GTX 470		24280 Mpixels/sec
GeForce GTX 460 (OEM)		20800 Mpixels/sec
	Difference: 3480 (17%)

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 max amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels 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 clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
