Is there something in Titan XP I would benefit from for ML/DL/AI comparing to 1080Ti (except for extra 1GB)? I am considering getting 8c Ryzen with 1080Ti (1-2x) and am wondering if Titan XP has something that would render 1080Ti obsolete for training models?

In terms of architecture and features the 1080ti and Titan Xp are the same, the only difference is the Titan Xp is slightly faster and has 1GB extra VRAM.

If your workload can be efficiently split between multiple cards then a $1400 pair of 1080tis will vastly outperform a $1200 Titan Xp - 16% more money for nearly double the throughput.

Great! That's what I wanted to know! Many thanks!

I was more curious if Titans had some lower precision data type or better dataset packing than vanilla Pascals, or something similar that would help with ML.

Another poster said that the drivers will prevent you running more than two 1080Ti's properly in the same machine (if I interpret it correctly).

In case you are just checking on your comment thread, do check the other threads as there's interesting performance comparisons being discussed.

just a meta showerthought;

I was about to ask "What is it we expect from GPU companies in the next ten years? Why/how will they dominate computing/innovate in ways that we care/compute?"

you answered my question. I think now is the time to invest in Nvidia and any other GPU manufacturer as the ML/DL/AI field is on the precipice to explode computing in the next 15 years. (15 years happens much faster than you might think)

The 'problem' with the stock market is that most of these expectations are usually already priced in, i.e. NVDA's market cap today reflects expectations of massive future growth.

That said, NVDA's stock just went 7% down due to an analyst's downgrade (which in the long run is relatively meaningless), so if you'd want to buy NVDA stock and hold it long term now might be a good time.

Disclosure: I am long NVDA, and my stock picking track record is atrocious.

That's right.

The stock price reflects the market's overall expectation of all future cash flows discounted to the present value - all the way out to infinity.

When you buy at stock, you are implicitly betting that reality will exceed those expectations.

So, you just said that massive growth is priced in, and the fact you hold the stock implies that you are betting on even more massive growth - relative to expectations.

Correct. The bet here is that 1. we're only seeing the very early stages of what's possible with GPU-based DNNs and 2. while Wall St is certainly considering the future applications their fantasies are on the conservative side.

The main risks to this thesis are that 1. DL could turn out to be a short-lived trend or 2. a new semiconductor technology emerges that is 10x better suited for DL/ML (Google's new architecture?)

Does DNN == Deep Neural Network or Dynamic Neural Net?
"invest" can be interpreted multiple ways... stock and brain-space...

I think brain-space is the safer investment if we are not talking about getting rich from the stock but enrichening the cyber-sphere from that which can be developed in the ML/DL/AI space...
