GeForce GT 130 vs GeForce GTX 650 Ti

Intro

Compare all of that to the GeForce GTX 650 Ti, which comes with clock speeds of 928 MHz on the GPU, and 1350 MHz on the 1024 MB of GDDR5 memory. It features 768 SPUs as well as 64 Texture Address Units and 16 ROPs.

The GeForce GTX 650 Ti is a lot (more or less 395%) better at texture filtering than the GeForce GT 130. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 650 Ti is superior to the GeForce GT 130, by far. (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 maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's 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 output rate also depends 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.
