GeForce GTX Titan vs Geforce GTX 780

Intro

The GeForce GTX Titan comes with a core clock frequency of 837 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 384-bit bus, and makes use of a 28 nm design. It is comprised of 2688 SPUs, 224 Texture Address Units, and 48 ROPs.

Compare all that to the Geforce GTX 780, which has a GPU core clock speed of 863 MHz, and 3072 MB of GDDR5 memory running at 1502 MHz through a 384-bit bus. It also is comprised of 2304 Stream Processors, 192 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Both cards have the exact same memory bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce GTX Titan should be a small bit (approximately 13%) more effective at AF than the Geforce GTX 780. (explain)

GeForce GTX Titan 187488 Mtexels/sec
Geforce GTX 780 165696 Mtexels/sec
Difference: 21792 (13%)

Pixel Rate

The Geforce GTX 780 should be a small bit (approximately 3%) more effective at FSAA than the GeForce GTX Titan, and able to handle higher resolutions better. (explain)

Geforce GTX 780 41424 Mpixels/sec
GeForce GTX Titan 40176 Mpixels/sec
Difference: 1248 (3%)

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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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

MY GTX 780 Phantom has:
GPU clock: 1079MHZ
Memory clock: 1652MHz
It´s a Titan killer

I searching for the best vga to put it in my specs list for my lap?

NewGirlInTown says:

At almost half the price of the Titan and it can handle the best games the same? It's almost a no brainer.
Much better choice than even going with SLI OR Crossfire.
It's fast! Crisp clean visuals. Fast FPS. No lag due to your card.
As another commenter said, It's a Titan killer!
