GeForce GT 440 3GB vs Geforce GTX 760

Intro

Compare those specs to the Geforce GTX 760, which has GPU clock speed of 980 MHz, and 2048 MB of GDDR5 RAM set to run at 1502 MHz through a 256-bit bus. It also is made up of 1152 SPUs, 96 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 440 3GB		56 Watts
Geforce GTX 760		170 Watts
	Difference: 114 Watts (204%)

Memory Bandwidth

Theoretically, the Geforce GTX 760 should perform much faster than the GeForce GT 440 3GB in general. (explain)

Geforce GTX 760		192256 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 149056 (345%)

Texel Rate

The Geforce GTX 760 should be quite a bit (about 560%) more effective at anisotropic filtering than the GeForce GT 440 3GB. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 79824 (560%)

Pixel Rate

If using a high resolution is important to you, then the Geforce GTX 760 is superior to the GeForce GT 440 3GB, and very much so. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce GT 440 3GB		14256 Mpixels/sec
	Difference: 17104 (120%)

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 information (in units of MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
