GeForce GT 440 3GB vs GeForce GTX 650 Ti

Intro

Compare all 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 RAM runs at a speed of 1350 MHz on this specific model. It features 768 SPUs as well as 64 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce GTX 650 Ti should be 100% quicker than the GeForce GT 440 3GB in general, due to its higher bandwidth. (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 will be a lot (more or less 317%) better at AF 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 using high levels of AA is important to you, then the GeForce GTX 650 Ti is a better choice, though only just barely. (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 (in units of megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units 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 fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
