GeForce GT 130 vs GeForce GTX 590

Intro

Compare those specs to the GeForce GTX 590, which features GPU clock speed of 607 MHz, and 1536 MB of GDDR5 memory running at 855 MHz through a 384-bit bus. It also is comprised of 512 SPUs, 64 Texture Address Units, and 48 ROPs.

GeForce GT 130		12000 MB/sec
	Difference: 316320 (2636%)

Texel Rate

The GeForce GTX 590 should be quite a bit (about 547%) faster with regards to texture filtering than the GeForce GT 130. (explain)

GeForce GTX 590		77696 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 65696 (547%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 590 is the winner, by far. (explain)

GeForce GTX 590		58272 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 50272 (628%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the 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 number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
