GeForce GT 440 1.5GB vs Nvidia Titan X

Intro

Compare all of that to the Nvidia Titan X, which has GPU clock speed of 1417 MHz, and 12288 MB of GDDR5X memory set to run at 1251 MHz through a 384-bit bus. It also features 3584 Stream Processors, 224 TAUs, and 96 Raster Operation Units.

In theory, the Nvidia Titan X should be 1038% quicker than the GeForce GT 440 1.5GB overall, because of its higher bandwidth. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GT 440 1.5GB		43200 MB/sec
	Difference: 448320 (1038%)

Texel Rate

The Nvidia Titan X is quite a bit (about 2126%) faster with regards to texture filtering than the GeForce GT 440 1.5GB. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 303152 (2126%)

Pixel Rate

The Nvidia Titan X should be quite a bit (about 854%) better at anti-aliasing than the GeForce GT 440 1.5GB, and capable of handling higher resolutions without losing too much performance. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GT 440 1.5GB		14256 Mpixels/sec
	Difference: 121776 (854%)

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 (measured in megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This 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 graphics 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 most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
