GeForce GTX Titan Black vs Geforce GTX 780

Intro

The GeForce GTX Titan Black comes with a core clock frequency of 889 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 384-bit memory bus, and makes use of a 28 nm design. It is comprised of 2880 SPUs, 240 Texture Address Units, and 48 Raster Operation Units.

Compare all that to the Geforce GTX 780, which comes with core speeds of 863 MHz on the GPU, and 1502 MHz on the 3072 MB of GDDR5 RAM. It features 2304 SPUs as well as 192 TAUs and 48 ROPs.

Geforce GTX 780 10082 points
Difference: 1584 (16%)

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX Titan Black should be 17% quicker than the Geforce GTX 780 in general, due to its higher bandwidth. (explain)

GeForce GTX Titan Black 336000 MB/sec
Geforce GTX 780 288384 MB/sec
Difference: 47616 (17%)

Texel Rate

The GeForce GTX Titan Black should be a lot (more or less 29%) better at anisotropic filtering than the Geforce GTX 780. (explain)

GeForce GTX Titan Black 213360 Mtexels/sec
Geforce GTX 780 165696 Mtexels/sec
Difference: 47664 (29%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX Titan Black is superior to the Geforce GTX 780, not by a very large margin though. (explain)

GeForce GTX Titan Black 42672 Mpixels/sec
Geforce GTX 780 41424 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 largest amount of data (measured in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
