Geforce GTX 770 vs Nvidia Titan X

Intro

The Geforce GTX 770 comes with a GPU clock speed of 1046 MHz, and the 2048 MB of GDDR5 RAM runs at 1753 MHz through a 256-bit bus. It also is made up of 1536 SPUs, 128 Texture Address Units, and 32 ROPs.

Compare all of that to the Nvidia Titan X, which features a GPU core clock speed of 1417 MHz, and 12288 MB of GDDR5X memory set to run at 1251 MHz through a 384-bit bus. It also is made up of 3584 SPUs, 224 Texture Address Units, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 770 230 Watts
Nvidia Titan X 250 Watts
Difference: 20 Watts (9%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X will be 119% quicker than the Geforce GTX 770 in general, due to its higher data rate. (explain)

Nvidia Titan X 491520 MB/sec
Geforce GTX 770 224384 MB/sec
Difference: 267136 (119%)

Texel Rate

The Nvidia Titan X is a lot (more or less 137%) more effective at texture filtering than the Geforce GTX 770. (explain)

Nvidia Titan X 317408 Mtexels/sec
Geforce GTX 770 133888 Mtexels/sec
Difference: 183520 (137%)

Pixel Rate

The Nvidia Titan X should be quite a bit (more or less 306%) more effective at full screen anti-aliasing than the Geforce GTX 770, and also will be able to handle higher resolutions without losing too much performance. (explain)

Nvidia Titan X 136032 Mpixels/sec
Geforce GTX 770 33472 Mpixels/sec
Difference: 102560 (306%)

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 max amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also 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 of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
