GeForce GT 130 vs GeForce GTX 650 Ti

Intro

Compare that to the GeForce GTX 650 Ti, which makes use of a 28 nm design. nVidia has clocked the core speed at 928 MHz. The GDDR5 memory is set to run at a speed of 1350 MHz on this particular card. It features 768 SPUs as well as 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

As far as performance goes, the GeForce GTX 650 Ti should in theory be much superior to the GeForce GT 130 overall. (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 will be a lot (more or less 86%) better at FSAA than the GeForce GT 130, and also will be capable of handling higher resolutions better. (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: Bandwidth is the largest amount of data (counted in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the 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 - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
