GeForce GT 240 GDDR5 1GB vs GeForce GTX 1080

Intro

Compare those specs to the GeForce GTX 1080, which uses a 16 nm design. nVidia has set the core frequency at 1607 MHz. The GDDR5X RAM is set to run at a speed of 1251 MHz on this card. It features 2560 SPUs along with 160 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 240 GDDR5 1GB		70 Watts
GeForce GTX 1080		180 Watts
	Difference: 110 Watts (157%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1080 will be 502% faster than the GeForce GT 240 GDDR5 1GB overall, due to its greater bandwidth. (explain)

GeForce GTX 1080		327680 MB/sec
GeForce GT 240 GDDR5 1GB		54400 MB/sec
	Difference: 273280 (502%)

Texel Rate

The GeForce GTX 1080 should be much (more or less 1361%) better at AF than the GeForce GT 240 GDDR5 1GB. (explain)

GeForce GTX 1080		257120 Mtexels/sec
GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
	Difference: 239520 (1361%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 1080 is the winner, and very much so. (explain)

GeForce GTX 1080		102848 Mpixels/sec
GeForce GT 240 GDDR5 1GB		4400 Mpixels/sec
	Difference: 98448 (2237%)

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 information (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. 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 lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
