GeForce GTX Titan vs Geforce GTX 780

Intro

Compare all of that to the Geforce GTX 780, which features a GPU core clock speed of 863 MHz, and 3072 MB of GDDR5 RAM running at 1502 MHz through a 384-bit bus. It also features 2304 SPUs, 192 TAUs, and 48 ROPs.

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 bit (about 13%) more effective at 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 should be a small bit (approximately 3%) faster with regards to FSAA than the GeForce GTX Titan, and capable of handling higher screen resolutions without losing too much performance. (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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. 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 lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
