GeForce GT 130 vs GeForce GTX 460 SE

Intro

Compare those specifications to the GeForce GTX 460 SE, which features clock speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 288 SPUs as well as 48 Texture Address Units and 32 ROPs.

GeForce GT 130		12000 MB/sec
	Difference: 96800 (807%)

Texel Rate

The GeForce GTX 460 SE will be quite a bit (approximately 160%) better at AF than the GeForce GT 130. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 19200 (160%)

Pixel Rate

The GeForce GTX 460 SE will be quite a bit (more or less 160%) more effective at full screen anti-aliasing than the GeForce GT 130, and should be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 12800 (160%)

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 maximum amount of data (in units of MB per second) that can be moved over the external memory interface in one 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 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 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 number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
