Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
GeForce GTS 450		106 Watts
	Difference: 31 Watts (41%)

Memory Bandwidth

In theory, the GeForce GTS 450 will be 381% quicker than the GeForce GT 130 in general, because of its higher data rate. (explain)

GeForce GTS 450		57728 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 45728 (381%)

Texel Rate

The GeForce GTS 450 is much (more or less 109%) better at texture filtering than the GeForce GT 130. (explain)

GeForce GTS 450		25056 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 13056 (109%)

Pixel Rate

The GeForce GTS 450 is much (more or less 57%) faster with regards to FSAA than the GeForce GT 130, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTS 450		12528 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 4528 (57%)

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 transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video 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 colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
