GeForce GT 130 vs GeForce GTX 460

Intro

Compare that to the GeForce GTX 460, which has core clock speeds of 675 MHz on the GPU, and 900 MHz on the 768 MB of GDDR5 RAM. It features 336 SPUs along with 56 Texture Address Units and 24 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce GTX 460 should be a lot faster than the GeForce GT 130 in general. (explain)

GeForce GTX 460		86400 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 74400 (620%)

Texel Rate

The GeForce GTX 460 should be quite a bit (about 215%) more effective at anisotropic filtering than the GeForce GT 130. (explain)

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

Pixel Rate

The GeForce GTX 460 should be quite a bit (approximately 103%) better at full screen anti-aliasing than the GeForce GT 130, and capable of handling higher resolutions better. (explain)

GeForce GTX 460		16200 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 8200 (103%)

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 max amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
