GeForce 8300 GS (OEM) vs GeForce GTX 660 Ti

Intro

Compare those specifications to the GeForce GTX 660 Ti, which makes use of a 28 nm design. nVidia has set the core frequency at 915 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this specific model. It features 1344 SPUs along with 112 TAUs and 24 ROPs.

GeForce GTX 660 Ti		150 Watts
	Difference: 110 Watts (275%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 660 Ti should in theory be quite a bit superior to the GeForce 8300 GS (OEM) in general. (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 should be quite a bit (about 5593%) better 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

If running with lots of anti-aliasing is important to you, then the GeForce GTX 660 Ti is a better choice, by a large margin. (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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 are processed per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
