GeForce 9800 GTX+		145 Watts
GeForce GTX 470		215 Watts
	Difference: 70 Watts (48%)

Memory Bandwidth

In theory, the GeForce GTX 470 should be 90% faster than the GeForce 9800 GTX+ overall, due to its higher data rate. (explain)

GeForce GTX 470		133920 MB/sec
GeForce 9800 GTX+		70400 MB/sec
	Difference: 63520 (90%)

Texel Rate

The GeForce 9800 GTX+ is a lot (more or less 39%) better at AF than the GeForce GTX 470. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
GeForce GTX 470		33992 Mtexels/sec
	Difference: 13240 (39%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 470 is superior to the GeForce 9800 GTX+, by far. (explain)

GeForce GTX 470		24280 Mpixels/sec
GeForce 9800 GTX+		11808 Mpixels/sec
	Difference: 12472 (106%)

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 information (measured in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock 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 also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
