GeForce GT 130 vs GeForce GTX 460 2GB

Intro

Compare all of that to the GeForce GTX 460 2GB, which makes use of a 40 nm design. nVidia has set the core speed at 675 MHz. The GDDR5 memory works at a frequency of 900 MHz on this card. It features 336 SPUs along with 56 TAUs and 32 Rasterization Operator Units.

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
GeForce GTX 460 2GB		160 Watts
	Difference: 85 Watts (113%)

Memory Bandwidth

The GeForce GTX 460 2GB should in theory be a lot faster than the GeForce GT 130 overall. (explain)

GeForce GTX 460 2GB		115200 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 103200 (860%)

Texel Rate

The GeForce GTX 460 2GB will be quite a bit (approximately 215%) faster with regards to texture filtering than the GeForce GT 130. (explain)

GeForce GTX 460 2GB		37800 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 25800 (215%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 460 2GB is a better choice, by a large margin. (explain)

GeForce GTX 460 2GB		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: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

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