Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GTS (G92)		135 Watts
GeForce 9800 GTX+		145 Watts
	Difference: 10 Watts (7%)

Memory Bandwidth

In theory, the GeForce 9800 GTX+ will be 13% quicker than the GeForce 8800 GTS (G92) in general, because of its higher bandwidth. (explain)

GeForce 9800 GTX+		70400 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 8320 (13%)

Texel Rate

The GeForce 9800 GTX+ is just a bit (more or less 14%) better at AF than the GeForce 8800 GTS (G92). (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
GeForce 8800 GTS (G92)		41600 Mtexels/sec
	Difference: 5632 (14%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 9800 GTX+ is superior to the GeForce 8800 GTS (G92), but only just. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 1408 (14%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can 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 ROPs by the the card's clock speed. 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 rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
