GeForce GTX 470 vs GeForce GTX 550 Ti

Intro

Compare all of that to the GeForce GTX 550 Ti, which uses a 40 nm design. nVidia has clocked the core frequency at 900 MHz. The GDDR5 RAM works at a speed of 1026 MHz on this particular card. It features 192 SPUs as well as 32 Texture Address Units and 24 Rasterization Operator Units.

Memory Bandwidth

The GeForce GTX 470, in theory, should be quite a bit faster than the GeForce GTX 550 Ti in general. (explain)

GeForce GTX 470		133920 MB/sec
GeForce GTX 550 Ti		98496 MB/sec
	Difference: 35424 (36%)

Texel Rate

The GeForce GTX 470 should be just a bit (about 18%) more effective at anisotropic filtering than the GeForce GTX 550 Ti. (explain)

GeForce GTX 470		33992 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 5192 (18%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 470 is the winner, but it probably won't make a huge difference. (explain)

GeForce GTX 470		24280 Mpixels/sec
GeForce GTX 550 Ti		21600 Mpixels/sec
	Difference: 2680 (12%)

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 largest amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
