GeForce GT 240 GDDR5 1GB vs GeForce GTX Titan

Intro

Compare all that to the GeForce GTX Titan, which comes with a GPU core clock speed of 837 MHz, and 6144 MB of GDDR5 RAM running at 1502 MHz through a 384-bit bus. It also is comprised of 2688 Stream Processors, 224 Texture Address Units, and 48 Raster Operation Units.

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan should be 430% quicker than the GeForce GT 240 GDDR5 1GB in general, because of its higher data rate. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce GT 240 GDDR5 1GB		54400 MB/sec
	Difference: 233984 (430%)

Texel Rate

The GeForce GTX Titan will be quite a bit (more or less 965%) faster with regards to AF than the GeForce GT 240 GDDR5 1GB. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
	Difference: 169888 (965%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX Titan is the winner, by far. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce GT 240 GDDR5 1GB		4400 Mpixels/sec
	Difference: 35776 (813%)

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 information (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
