GeForce GT 130 vs Geforce GTX 670

Intro

Compare all of that to the Geforce GTX 670, which features a GPU core clock speed of 915 MHz, and 2048 MB of GDDR5 memory set to run at 1500 MHz through a 256-bit bus. It also is comprised of 1344 SPUs, 112 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
Geforce GTX 670		170 Watts
	Difference: 95 Watts (127%)

Memory Bandwidth

The Geforce GTX 670, in theory, should perform quite a bit faster than the GeForce GT 130 in general. (explain)

Geforce GTX 670		192000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 180000 (1500%)

Texel Rate

The Geforce GTX 670 will be a lot (more or less 754%) better at AF than the GeForce GT 130. (explain)

Geforce GTX 670		102480 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 90480 (754%)

Pixel Rate

If using a high screen resolution is important to you, then the Geforce GTX 670 is superior to the GeForce GT 130, by a large margin. (explain)

Geforce GTX 670		29280 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 21280 (266%)

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 largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of 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 number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
