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

Intro

Compare all of that to the GeForce GTX 650 Ti 2GB, which comes with GPU clock speed of 928 MHz, and 2048 MB of GDDR5 RAM set to run at 1350 MHz through a 128-bit bus. It also features 768 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 440 3GB		56 Watts
GeForce GTX 650 Ti 2GB		110 Watts
	Difference: 54 Watts (96%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 Ti 2GB should perform much faster than the GeForce GT 440 3GB overall. (explain)

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 will be a lot (more or less 317%) more effective at 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 the winner, but it probably won't make a huge difference. (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 data (in units of megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
