GeForce GT 430 vs GeForce GTX 550 Ti

Intro

Compare all that to the GeForce GTX 550 Ti, which comes with clock speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 RAM. It features 192 SPUs as well as 32 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430		60 Watts
GeForce GTX 550 Ti		116 Watts
	Difference: 56 Watts (93%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 550 Ti should be much faster than the GeForce GT 430 in general. (explain)

GeForce GTX 550 Ti		98496 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 69696 (242%)

Texel Rate

The GeForce GTX 550 Ti should be quite a bit (about 157%) more effective at anisotropic filtering than the GeForce GT 430. (explain)

GeForce GTX 550 Ti		28800 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 17600 (157%)

Pixel Rate

The GeForce GTX 550 Ti will be a lot (more or less 671%) more effective at AA than the GeForce GT 430, and also will be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 18800 (671%)

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 max amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 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 the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
