Hey Keith and Al, what do you all think? https://www.pcper.com/news/Processors/AMD-EPYC-Rome-Rumors-7nm-64-Cores-2-Designs |

I believe the "Rome"processor was on the cpu timeline PowerPoint slides at the inaugural Ryzen launch. So nothing unexpected. I have gathered that the TSMC foundry 7nm fab line is further along that many thought. The thinking though was that Qualcomm and Apple would have first shot at production relegating AMD to fill in the minimal production gap slots. Therefore, the "Rome" processors wouldn't be available in any quantities other than engineering samples to whet the datacenter purchasing managers appetites in late 2018. Maybe some slight product availability in 2019. Question is who will get priority at AMD, Zen2 or Navi GPU's for the 7nm parts. Does AMD think there is greater chance to grab market share in gpus or cpus? Granted a 128 thread cpu boggles the mind.

My thought is ... SETI has a 100 task limit per device and couldn't even feed it, LOL. |

Hide your credit cards. Just imagine the price of each one of this toys. A simple math... 128 (threads) x 1 hr (crunch time per WU) x 24 hrs = > 3000 WU /Day per CPU... Something like > 200K/day even with Creditscrew. If is possible to keep it feeded of course. |

Hide your credit cards. Just imagine the price of each one of this toys. You need to rework your math. In my case . . . 128 threads X 30minutes (crunch time per WU and SSE41 app) X 24 hours => 6144 WU /Day per CPU >> 307K/day at 50 credits per WU with CreditScrew.

My thought is ... SETI has a 100 task limit per device and couldn't even feed it, LOL. But the developers write the scheduler code. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

Welll! Look at that won't you.. I bet its clocked relatively low, that seems to be the rule, the more cores, the slower the GHz. It'll be interesting when I get my 44/88 core system up and running (RedHat. Yeah, I know, I know, getting there...) but that wouldn't hold a candle to this 128 core monster. Any guesses as to the cost per chip? Imagine 2 of those on a server board.. Redonkulous! SETI wouldn't know what to do with it! lol |

Haven't a clue. What package? How many dies per package? If it follows Epyc layout, it would have 4 full active dies. Will they keep the 4094 contacts of the SP3r2 socket? Or have to add more and new socket density? Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |
