Here's hoping for an A100 titan with un-nerfed FP64. The 3090 is twice as nerfed as previous generations, which were also bad at 1:32. Now it's 1:64 :(

- p1esk 6y agoFP64 is not needed for deep learning.
- jjoonathan 6y agoWhat makes you think I'm doing deep learning?

- Dylan16807 6y agoThe FP64 units are a separate addition that eat a lot of die space, right? I wouldn't use the word "nerf" for the tradeoff between having more SMs versus having more features in the SMs.
- jjoonathan 6y agoThey eat die space but not TDP.
- lsb 6y agoWhat workloads do you run that require fp64?
- jjoonathan 6y agoSimulation.
- bitL 6y agoRadeon VII is the best bang for the bucks in the FP64 space, then older K80s. Titan V/V100 are still expensive.
- jjoonathan 6y agoYep! I've got CUDA, so I still have to pay the green tax.
- nullifidian 6y agoIt seems that Radeon VII and Titan V are the last cards with decent fp64 performance for foreseeable future. Both Nvidia and AMD now basically have different architectures for their consumer and data-center products.
- jjoonathan 6y agoYep, sure looks that way. I'll still be dreaming of a Titan A!
