GeForce GT 440 3GB vs GeForce GTX 970

Intro

Compare those specs to the GeForce GTX 970, which makes use of a 28 nm design. nVidia has set the core speed at 1050 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this specific card. It features 1664 SPUs as well as 104 Texture Address Units and 64 Rasterization Operator Units.

Texel Rate

The GeForce GTX 970 is a lot (about 666%) more effective at anisotropic filtering than the GeForce GT 440 3GB. (explain)

GeForce GTX 970		109200 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 94944 (666%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 970 is the winner, by far. (explain)

GeForce GTX 970		67200 Mpixels/sec
GeForce GT 440 3GB		14256 Mpixels/sec
	Difference: 52944 (371%)

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 largest amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling 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 card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
