GeForce 9800 GTX vs GeForce GTX 550 Ti

Intro

Compare all of that to the GeForce GTX 550 Ti, which has a clock frequency of 900 MHz and a GDDR5 memory speed of 1026 MHz. It also makes use of a 192-bit memory bus, and uses a 40 nm design. It features 192 SPUs, 32 TAUs, and 24 Raster Operation Units.

GeForce GTX 550 Ti		116 Watts
GeForce 9800 GTX		140 Watts
	Difference: 24 Watts (21%)

Memory Bandwidth

The GeForce GTX 550 Ti, in theory, should be a lot faster than the GeForce 9800 GTX in general. (explain)

GeForce GTX 550 Ti		98496 MB/sec
GeForce 9800 GTX		70400 MB/sec
	Difference: 28096 (40%)

Texel Rate

The GeForce 9800 GTX should be much (more or less 50%) faster with regards to AF than the GeForce GTX 550 Ti. (explain)

GeForce 9800 GTX		43200 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 14400 (50%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 550 Ti is a better choice, by far. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
GeForce 9800 GTX		10800 Mpixels/sec
	Difference: 10800 (100%)

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 (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
