GeForce GT 440 3GB vs Nvidia Titan X

Intro

Compare those specs to the Nvidia Titan X, which makes use of a 16 nm design. nVidia has clocked the core frequency at 1417 MHz. The GDDR5X RAM runs at a speed of 1251 MHz on this card. It features 3584 SPUs as well as 224 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 440 3GB		56 Watts
Nvidia Titan X		250 Watts
	Difference: 194 Watts (346%)

Memory Bandwidth

The Nvidia Titan X, in theory, should perform quite a bit faster than the GeForce GT 440 3GB overall. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 448320 (1038%)

Texel Rate

The Nvidia Titan X should be a lot (more or less 2126%) faster with regards to texture filtering than the GeForce GT 440 3GB. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 303152 (2126%)

Pixel Rate

The Nvidia Titan X should be quite a bit (approximately 854%) more effective at full screen anti-aliasing than the GeForce GT 440 3GB, and also should be capable of handling higher resolutions while still performing well. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GT 440 3GB		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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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 bandwidth is, the lower the potential to get to the maximum fill rate.
