GeForce GT 450 (OEM) vs GeForce GTX 550 Ti

Intro

Compare those specifications to the GeForce GTX 550 Ti, which comes with core speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 memory. It features 192 SPUs along with 32 TAUs and 24 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 450 (OEM)		106 Watts
GeForce GTX 550 Ti		116 Watts
	Difference: 10 Watts (9%)

Memory Bandwidth

In theory, the GeForce GTX 550 Ti should be a small bit faster than the GeForce GT 450 (OEM) in general. (explain)

GeForce GTX 550 Ti		98496 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 2496 (3%)

Texel Rate

The GeForce GTX 550 Ti is a lot (more or less 52%) faster with regards to AF than the GeForce GT 450 (OEM). (explain)

GeForce GTX 550 Ti		28800 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 9840 (52%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 550 Ti is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
GeForce GT 450 (OEM)		18960 Mpixels/sec
	Difference: 2640 (14%)

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 largest amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 maximum number of pixels that the graphics chip 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 Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
