GeForce GT 130 vs GeForce GTX 460 (OEM)

Intro

Compare those specs to the GeForce GTX 460 (OEM), which comes with a clock frequency of 650 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 256-bit bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 56 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
GeForce GTX 460 (OEM)		150 Watts
	Difference: 75 Watts (100%)

Memory Bandwidth

The GeForce GTX 460 (OEM), in theory, should perform a lot faster than the GeForce GT 130 overall. (explain)

GeForce GTX 460 (OEM)		108800 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 96800 (807%)

Texel Rate

The GeForce GTX 460 (OEM) should be much (approximately 203%) more effective at AF than the GeForce GT 130. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 24400 (203%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 (OEM) is a better choice, and very much so. (explain)

GeForce GTX 460 (OEM)		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 max amount of data (in units of megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that can be applied per second. This number 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
