Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT DDR2		50 Watts
GeForce GTX 560		150 Watts
	Difference: 100 Watts (200%)

Memory Bandwidth

In theory, the GeForce GTX 560 should be 701% quicker than the GeForce 9500 GT DDR2 overall, because of its higher data rate. (explain)

GeForce GTX 560		128128 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 112128 (701%)

Texel Rate

The GeForce GTX 560 should be much (approximately 415%) more effective at AF than the GeForce 9500 GT DDR2. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 36560 (415%)

Pixel Rate

The GeForce GTX 560 should be quite a bit (about 489%) faster with regards to AA than the GeForce 9500 GT DDR2, and should be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 21520 (489%)

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 maximum amount of information (counted in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
