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

Theoretically speaking, the GeForce 9800 GTX+ will be 13% faster than the GeForce 8800 GTS (G92) in general, because of its greater bandwidth. (explain)

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

Texel Rate

The GeForce 9800 GTX+ should be a little bit (more or less 14%) faster with regards to 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

The GeForce 9800 GTX+ is just a bit (more or less 14%) better at full screen anti-aliasing than the GeForce 8800 GTS (G92), and should be capable of handling higher screen resolutions better. (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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated 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 applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
