In theory, the GeForce GTX 660 Ti is 2150% faster than the GeForce 8300 GS (OEM) overall, because of its greater data rate. (explain)

GeForce GTX 660 Ti		144000 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 137600 (2150%)

Texel Rate

The GeForce GTX 660 Ti will be a lot (about 5593%) more effective at texture filtering than the GeForce 8300 GS (OEM). (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 100680 (5593%)

Pixel Rate

The GeForce GTX 660 Ti should be quite a bit (approximately 2340%) faster with regards to anti-aliasing than the GeForce 8300 GS (OEM), and also will be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 21060 (2340%)

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 (in units of MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines 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 output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
