GeForce GT 130 vs GeForce GTX 460 1GB

Intro

Compare all of that to the GeForce GTX 460 1GB, which features a core clock speed of 675 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 256-bit bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

In theory, the GeForce GTX 460 1GB should be 860% quicker than the GeForce GT 130 in general, due to its higher data rate. (explain)

GeForce GTX 460 1GB		115200 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 103200 (860%)

Texel Rate

The GeForce GTX 460 1GB should be quite a bit (approximately 215%) faster with regards to anisotropic filtering than the GeForce GT 130. (explain)

GeForce GTX 460 1GB		37800 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 25800 (215%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 460 1GB is the winner, by a large margin. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 13600 (170%)

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 largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at 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 the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
