GeForce GT 440 3GB vs GeForce GTX 650 Ti

Intro

Compare all that to the GeForce GTX 650 Ti, which has clock speeds of 928 MHz on the GPU, and 1350 MHz on the 1024 MB of GDDR5 RAM. It features 768 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

As far as performance goes, the GeForce GTX 650 Ti should theoretically be a lot superior to the GeForce GT 440 3GB in general. (explain)

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

Texel Rate

The GeForce GTX 650 Ti is much (more or less 317%) better at texture filtering than the GeForce GT 440 3GB. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 650 Ti is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 650 Ti		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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of 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 quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
