GeForce GT 240 GDDR5 1GB vs GeForce GTX Titan X

Intro

Compare those specifications to the GeForce GTX Titan X, which uses a 28 nm design. nVidia has set the core frequency at 1000 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this particular card. It features 3072 SPUs along with 192 Texture Address Units and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce GTX Titan X should perform a lot faster than the GeForce GT 240 GDDR5 1GB overall. (explain)

GeForce GTX Titan X		336000 MB/sec
GeForce GT 240 GDDR5 1GB		54400 MB/sec
	Difference: 281600 (518%)

Texel Rate

The GeForce GTX Titan X will be quite a bit (approximately 991%) more effective at AF than the GeForce GT 240 GDDR5 1GB. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
	Difference: 174400 (991%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX Titan X is a better choice, and very much so. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
GeForce GT 240 GDDR5 1GB		4400 Mpixels/sec
	Difference: 91600 (2082%)

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 megabytes per second) that can be transported across 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 the card has DDR type memory, it should 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 AA, HDR 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 number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
