By all metrics in almost all markets, Nvidia is dominant in high end GPU sales, it isn't a 50/50 market. On Steam they are at 60% vs AMDs 23% (http://store.steampowered.com/hwsurvey). All major cloud computing providers deploy Nvidia GPUs and in scientific computing and machine learning they own close to 100% of the market. AMD is only really dominant in game consoles, which is the lowest margin GPU market. OpenCL just doesn't have the software support that CUDA has for scientific computing, and much of that is because Nvidia actively works to support that community.

Then it's unfortunate Apple decided to integrate AMD and Intel cards into MacBook Pro's instead of Nvidia. Many ML researchers probably use MBP's but can't leverage acceleration.

You wouldn't wanna run long-running models that take days to train on your laptop anyway.

No but you would want to develop them on a truncated set of the data without being tethered to the internet.

It's a reasonable use case.

Eh, it's not really that consequential because anything big will need way more horsepower than you're gonna get on any mobile GPU to be able to done in a reasonable amount of time. We built a CLI tool for our stuff on AWS and our gaming/ML desktop at the office specifically because everyone is on laptops and training or evals are so slow.

It really is. I stopped playing around with CUDA precisely because Apple dropped Nvidia GPUs. Granted to anything serious you want something other than a laptop but it's still nice for quick prototyping (I'm referring to CUDA in general not just using it for ML).
