GeForce GT 240 GDDR5 1GB vs Nvidia Titan X

Intro

Compare all that to the Nvidia Titan X, which comes with core speeds of 1417 MHz on the GPU, and 1251 MHz on the 12288 MB of GDDR5X memory. It features 3584 SPUs as well as 224 Texture Address Units and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 240 GDDR5 1GB		70 Watts
Nvidia Titan X		250 Watts
	Difference: 180 Watts (257%)

Memory Bandwidth

In theory, the Nvidia Titan X is 804% quicker than the GeForce GT 240 GDDR5 1GB overall, because of its greater bandwidth. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GT 240 GDDR5 1GB		54400 MB/sec
	Difference: 437120 (804%)

Texel Rate

The Nvidia Titan X is a lot (more or less 1703%) faster with regards to anisotropic filtering than the GeForce GT 240 GDDR5 1GB. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
	Difference: 299808 (1703%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Nvidia Titan X is the winner, and very much so. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GT 240 GDDR5 1GB		4400 Mpixels/sec
	Difference: 131632 (2992%)

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 (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
