Geforce GTX 770 vs Nvidia Titan X

Intro

The Geforce GTX 770 features core speeds of 1046 MHz on the GPU, and 1753 MHz on the 2048 MB of GDDR5 memory. It features 1536 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

Compare those specs to the Nvidia Titan X, which has GPU 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 comprised of 3584 Stream Processors, 224 Texture Address Units, and 96 Raster Operation Units.

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

The Nvidia Titan X, in theory, should perform much faster than the Geforce GTX 770 overall. (explain)

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

Texel Rate

The Nvidia Titan X will be much (more or less 137%) better 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

If using high levels of AA is important to you, then the Nvidia Titan X is a better choice, and very much so. (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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
