GeForce GT 130 vs GeForce GTX 590

Intro

Compare those specifications to the GeForce GTX 590, which comes with a clock speed of 607 MHz and a GDDR5 memory frequency of 855 MHz. It also makes use of a 384-bit memory bus, and uses a 40 nm design. It features 512 SPUs, 64 TAUs, and 48 Raster Operation Units.

The GeForce GTX 590 should be quite a bit (more or less 547%) better at 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

The GeForce GTX 590 should be quite a bit (approximately 628%) better at AA than the GeForce GT 130, and will be able to handle higher screen resolutions more effectively. (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: Bandwidth is the max amount of data (measured in MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high 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 amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record 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 the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
