GeForce GTX Titan vs Geforce GTX 780

Intro

The GeForce GTX Titan features a GPU clock speed of 837 MHz, and the 6144 MB of GDDR5 memory is set to run at 1502 MHz through a 384-bit bus. It also features 2688 SPUs, 224 TAUs, and 48 ROPs.

Compare those specs to the Geforce GTX 780, which comes with 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 exactly the same memory bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The GeForce GTX Titan will be a small bit (about 13%) faster with regards to texture filtering 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 will be just a bit (more or less 3%) faster with regards to AA than the GeForce GTX Titan, and capable of handling higher resolutions without slowing down too much. (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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR 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 number 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 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 amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum 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!
