GeForce GT 440 3GB vs GeForce GTX 960

Intro

Compare all of that to the GeForce GTX 960, which uses a 28 nm design. nVidia has clocked the core frequency at 1127 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this specific model. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

GeForce GT 440 3GB		56 Watts
GeForce GTX 960		120 Watts
	Difference: 64 Watts (114%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 960 should be 159% faster than the GeForce GT 440 3GB overall, because of its higher data rate. (explain)

GeForce GTX 960		112000 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 68800 (159%)

Texel Rate

The GeForce GTX 960 is a lot (about 406%) faster with regards to AF than the GeForce GT 440 3GB. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 57872 (406%)

Pixel Rate

The GeForce GTX 960 should be much (approximately 153%) faster with regards to AA than the GeForce GT 440 3GB, and capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GT 440 3GB		14256 Mpixels/sec
	Difference: 21808 (153%)

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 MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card 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 number of colour ROPs by the the core clock speed. 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 rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
