GeForce 8300 GS (OEM) vs GeForce GTX 550 Ti

Intro

Compare those specifications to the GeForce GTX 550 Ti, which features a core clock speed of 900 MHz and a GDDR5 memory speed of 1026 MHz. It also uses a 192-bit memory bus, and uses a 40 nm design. It features 192 SPUs, 32 Texture Address Units, and 24 ROPs.

GeForce 8300 GS (OEM)		40 Watts
GeForce GTX 550 Ti		116 Watts
	Difference: 76 Watts (190%)

Memory Bandwidth

Performance-wise, the GeForce GTX 550 Ti should in theory be quite a bit better than the GeForce 8300 GS (OEM) overall. (explain)

GeForce GTX 550 Ti		98496 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 92096 (1439%)

Texel Rate

The GeForce GTX 550 Ti will be much (about 1500%) better at texture filtering than the GeForce 8300 GS (OEM). (explain)

GeForce GTX 550 Ti		28800 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 27000 (1500%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 550 Ti is the winner, and very much so. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 20700 (2300%)

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 max amount of data (counted in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
