GeForce GT 130 vs GeForce GTX 470

Intro

Compare those specs to the GeForce GTX 470, which uses a 40 nm design. nVidia has clocked the core speed at 607 MHz. The GDDR5 memory runs at a frequency of 837 MHz on this specific card. It features 448 SPUs along with 56 Texture Address Units and 40 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
GeForce GTX 470		215 Watts
	Difference: 140 Watts (187%)

Memory Bandwidth

Performance-wise, the GeForce GTX 470 should theoretically be quite a bit superior to the GeForce GT 130 in general. (explain)

GeForce GTX 470		133920 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 121920 (1016%)

Texel Rate

The GeForce GTX 470 is a lot (more or less 183%) more effective at texture filtering than the GeForce GT 130. (explain)

GeForce GTX 470		33992 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 21992 (183%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 470 is the winner, by far. (explain)

GeForce GTX 470		24280 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 16280 (204%)

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 information (measured in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
