GeForce GT 440 3GB vs GeForce GTX 550 Ti

Intro

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

GeForce GTX 550 Ti		116 Watts
	Difference: 60 Watts (107%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 550 Ti should in theory be a lot superior to the GeForce GT 440 3GB in general. (explain)

GeForce GTX 550 Ti		98496 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 55296 (128%)

Texel Rate

The GeForce GTX 550 Ti should be quite a bit (about 102%) more effective at texture filtering than the GeForce GT 440 3GB. (explain)

GeForce GTX 550 Ti		28800 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 14544 (102%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 550 Ti is a better choice, by a large margin. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
GeForce GT 440 3GB		14256 Mpixels/sec
	Difference: 7344 (52%)

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 moved past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it must 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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