GeForce GT 440 3GB vs GeForce GTX 650 Ti 2GB

Intro

Compare all that to the GeForce GTX 650 Ti 2GB, which comes with a GPU core clock speed of 928 MHz, and 2048 MB of GDDR5 memory running at 1350 MHz through a 128-bit bus. It also features 768 SPUs, 64 Texture Address Units, and 16 ROPs.

GeForce GTX 650 Ti 2GB		86400 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 43200 (100%)

Texel Rate

The GeForce GTX 650 Ti 2GB is much (approximately 317%) faster with regards to AF than the GeForce GT 440 3GB. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 45136 (317%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti 2GB is a better choice, though only just barely. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
GeForce GT 440 3GB		14256 Mpixels/sec
	Difference: 592 (4%)

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 (measured in megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
