I'm running P41s in one of my test boxes. These don't have support for BF16 but they do support F16 and F32 and those are accelerated to a certain degree, they're lacking kernels that are as optimized but its not terribly hard to adapt other ones for the purposes. You don't get great out-of-the-box performance but it only took me three work days or so with no experience writing these to adapt, test, and validate a kernel using the acceleration hardware that was available (no prior experience writing these kernels). They're not as powerful as others but still significantly better than running on a CPU alone and I'd bet my kernel is missing more advanced optimizations. My issue with these was the power cable and fans. The author touches on the fans and I did try a 3D printed shroud and some of the higher pressure fans but I could only run the cards in short stints. I ended up making an enclosure that went straight out of the case using two high pressure SAN array fans I harvested from the IT graveyard per card and making a hole with an angle grinder. The power cable is NOT STANDARD on these. I had to find a weird specific cable to adapt the standard 8-pin GPU connector and each card takes two of these bad boys.
