GeForce GT 130 vs GeForce GTX 650 Ti

Intro

Compare those specifications to the GeForce GTX 650 Ti, which makes use of a 28 nm design. nVidia has set the core frequency at 928 MHz. The GDDR5 memory is set to run at a frequency of 1350 MHz on this particular model. It features 768 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
GeForce GTX 650 Ti		110 Watts
	Difference: 35 Watts (47%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 Ti is 620% quicker than the GeForce GT 130 in general, because of its greater data rate. (explain)

GeForce GTX 650 Ti		86400 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 74400 (620%)

Texel Rate

The GeForce GTX 650 Ti should be quite a bit (approximately 395%) more effective at AF than the GeForce GT 130. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 47392 (395%)

Pixel Rate

The GeForce GTX 650 Ti is a lot (approximately 86%) more effective at FSAA than the GeForce GT 130, and should be able to handle higher resolutions more effectively. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 6848 (86%)

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 maximum amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
