GeForce 8300 GS (OEM) vs GeForce GTX 660 Ti

Intro

Compare those specs to the GeForce GTX 660 Ti, which comes with a clock frequency of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 192-bit bus, and makes use of a 28 nm design. It features 1344 SPUs, 112 Texture Address Units, and 24 Raster Operation Units.

GeForce 8300 GS (OEM)		40 Watts
GeForce GTX 660 Ti		150 Watts
	Difference: 110 Watts (275%)

Memory Bandwidth

In theory, the GeForce GTX 660 Ti is 2150% faster than the GeForce 8300 GS (OEM) overall, because of its greater bandwidth. (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 quite a bit (about 5593%) faster with regards to anisotropic 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 will be much (more or less 2340%) more effective at full screen anti-aliasing than the GeForce 8300 GS (OEM), and will be capable of handling higher screen resolutions while still performing well. (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 megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If 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 amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
