I'm looking forward to seeing this in stores, as I've wanted to build a new machine learning rig for some time. The GTX 1080 just didn't seem like it would do the trick, with ostensibly limited software support and all.

I'm specifically wondering about FP16 handling though. Single precision FLOPS are never mentioned in the blog, nor on the NVidia page. It would be a shame if the FP16 units on this card were gimped in the same way as the GTX 1080...

I don't think it'll be good. It's probably based on the same chips used in the GTX 1080 which doesn't have the FP16 improvements that GP100 has. I can't be a hundred percent on this since NVIDIA hasn't confirmed.

From Anandtech's 1080 review (page 2): "As a result while GP100 has some notable feature/design elements for HPC – things such faster FP64 & FP16 performance, ECC, and significantly greater amounts of shared memory and register file capacity per CUDA core – these elements aren’t present in GP104 (and presumably, future Pascal consumer-focused GPUs)."

NVIDIA is always publishing just the numbers that it wants to publish. There are still improvements, but they are slowing down.. I'm sure the engineers did their best.

The announcement skipped energy usage as well.

The GTX1080 still isn't available anyway, unless you pay an exorbitant sum to a scalper.

I've been able to get 1070 and 1080s at retail price by backordering through B&H; they took 2 extra days to ship but NBD.

Funny, my friend had no issue getting two of them. The only impossible to get model is gigabyte's xtreme version and it's not even the 'best'.

From which vendor, may I ask?

Zotac Extreme.

Cool. Who has it in stock?

A month ago you'd be right. As it is, all manufacturers are stocking their cards pretty regularly it you set up notifications for em.

I've had notifications set up on Newegg for every variant and I have been notified for only two of the lesser variants, and by the time I check the site it's already out of stock.
