GeForce GT 130 vs GeForce GTX 750 Ti

Intro

Compare those specs to the GeForce GTX 750 Ti, which features core clock speeds of 1020 MHz on the GPU, and 1350 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
GeForce GT 130		75 Watts
	Difference: 15 Watts (25%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 Ti should be quite a bit faster than the GeForce GT 130 in general. (explain)

GeForce GTX 750 Ti		86400 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 74400 (620%)

Texel Rate

The GeForce GTX 750 Ti should be a lot (approximately 240%) better at anisotropic filtering than the GeForce GT 130. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 28800 (240%)

Pixel Rate

The GeForce GTX 750 Ti will be a lot (more or less 104%) more effective at AA than the GeForce GT 130, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 8320 (104%)

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 largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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.
