Guess that is maximum many of us can afford. Hence features that are missing from A100 is a bit moot. But the update we are wait. Still based on what we saw 3090 really does not worth the money. Still 24gb is 24gb.

If you run it 24/7, anyways the cost of electricity will be much more in a year or so. If you run it sparingly, within some time cloud based 30 series will be launched for sure.

What is the price of electricity where you live? For me to pay as much as the card is worth in electricity, even running it continuously, it would take 11 years.

Granted, electricity is exceedingly cheap here, but still, 11 years is a long time.

About $0.20/kWh here. Works out to $600 a year I think

When I first read the review, I couldn't understand why the author was mentioning that FP16 will surely be improved by new drivers despite not understanding that FP16 TFlops are exactly the same as FP32, tensor cores were nerfed and FP32 accumulate set to 0.5x speed, instead of Titan RTX's 1x. I'd say the results are as good as it gets, if you want a better performance, wait for Ampere Titan or Quadro.

I was under the impression the 3090 is the Titan of this generation.

I was as well, until I saw the Linus Tech Tips review of it: the drivers are (were?) missing support for some Titan optimizations -- the Titan RTX significantly beat the 3090 for a few benchmarks.

If the card doesn't have these optimizations, I would expect that an actual 30 series Titan is coming at some point... But the marketing has been really confusing, so who the hell knows.

Is there any reason NVIDIA aren't selling A100s as individual cards?

PCI Express variants are $8300 individually.

Neat, would love to try it but can’t buy the card anywhere. Another shitty Nvidia launch.

I'm looking forward to multi-gpu tests!

Would be good to see if it is worth upgrading x4 and x8 setups.

Single gpu upgrade being worth it is a no-brainer. Launch price of the 30xx cards is lower that then purchase-able price of the two comparison cards!

If only you could buy them though. The only microcenter in PA got 15 of each 30xx on respective launch days.

If anyone knows how many of these cards are being produced please do share.

They just have the wrong ptxas - needs Cuda 11.1 and properly set $PATH.

well ... it was wishful or hopeful thinking :-) I do hope to see better performance but I'm not as optimistic now as I was at first (got some pretty enlightening comments on the post)
