GeForce GT 240 GDDR5 vs GeForce GTX Titan

Intro

The GeForce GT 240 GDDR5 uses a 40 nm design. nVidia has set the core frequency at 550 MHz. The GDDR5 memory works at a frequency of 850 MHz on this card. It features 96 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Compare all of that to the GeForce GTX Titan, which comes with a core clock frequency of 837 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 384-bit memory bus, and uses a 28 nm design. It features 2688 SPUs, 224 TAUs, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce GTX Titan should be quite a bit faster than the GeForce GT 240 GDDR5 in general. (explain)

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

Texel Rate

The GeForce GTX Titan will be much (more or less 965%) more effective at texture filtering than the GeForce GT 240 GDDR5. (explain)

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

Pixel Rate

The GeForce GTX Titan should be much (approximately 813%) more effective at full screen anti-aliasing than the GeForce GT 240 GDDR5, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX Titan 40176 Mpixels/sec
GeForce GT 240 GDDR5 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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the 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 texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
