GeForce GT 130 vs GeForce GTX 580

Intro

Compare those specifications to the GeForce GTX 580, which features a core clock frequency of 772 MHz and a GDDR5 memory frequency of 1002 MHz. It also makes use of a 384-bit memory bus, and uses a 40 nm design. It is comprised of 512 SPUs, 64 TAUs, and 48 ROPs.

GeForce GTX 580		49408 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 37408 (312%)

Pixel Rate

The GeForce GTX 580 should be much (about 363%) faster with regards to AA than the GeForce GT 130, and also should be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 580		37056 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 29056 (363%)

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 (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
