GeForce GT 240 GDDR5 1GB vs GeForce GTX 980 Ti

Intro

Compare all of that to the GeForce GTX 980 Ti, which makes use of a 28 nm design. nVidia has clocked the core speed at 1000 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this specific card. It features 2816 SPUs along with 176 TAUs and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 240 GDDR5 1GB		70 Watts
GeForce GTX 980 Ti		250 Watts
	Difference: 180 Watts (257%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 980 Ti is 518% quicker than the GeForce GT 240 GDDR5 1GB in general, because of its greater bandwidth. (explain)

GeForce GTX 980 Ti		336000 MB/sec
GeForce GT 240 GDDR5 1GB		54400 MB/sec
	Difference: 281600 (518%)

Texel Rate

The GeForce GTX 980 Ti should be much (more or less 900%) more effective at AF than the GeForce GT 240 GDDR5 1GB. (explain)

GeForce GTX 980 Ti		176000 Mtexels/sec
GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
	Difference: 158400 (900%)

Pixel Rate

The GeForce GTX 980 Ti should be a lot (approximately 2082%) more effective at FSAA than the GeForce GT 240 GDDR5 1GB, and also will be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 980 Ti		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 maximum amount of data (measured in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the 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 write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
