AMD is giving Nvidia a run for its money with the Vega 20 rocking Radeon VII cranking out, supposedly, 6,912 GFLOPS of double-precision goodness. Source: https://www.techpowerup.com/gpu-specs/radeon-vii.c3358 For the sake of record: - Titan V costs $2,999 (DP of 7,450 GFLOPS) If the leaked specs are accurate, I feel like everyone running projects that benefit from FP64 performance (i.e. Milkyway@home) will grab this card like hot cake. IMO, Radeon VII is the saving grace for researchers in need of affordable DP accelerators. Everything stays But it still changes Ever so slightly Daily and nightly In little ways When everything stays...

That is very interesting. I would prefer lower power however; maybe they will come out with a lower-end version. |

Given the similarities between VII and MI50, the question of whether or not the gamer variant supported FP64 (double-precision floating-point) lingered after its announcement. At the show, I talked to an AMD rep who said the card didn’t support double-precision, and was further told that such a move would cannibalize sales of the higher-priced enterprise cards (which seems likely).https://techgage.com/news/radeon-vii-caps-fp64-performance/ We are out of luck after all. |

maybe we have luck Anandtech has confimred that vega vii wil have a DP ratio of 1:8. that 2 time the DP of of a vega 64 or 1.7TFlop DP. |

Just a FYI - The Titan V, on paper, has a DP of 7.4 TFlops but in real world performance for Milkyway its about half the speed of a Tesla V100 (which is rated the same). Then again it is half the price of a v100 so I guess that makes sense. |

maybe we have luck Let’s hope they will keep it at 1:8. 1.7TFLOPS is still better than any RTX cards right now, at least on paper. Edit: spelling Everything stays But it still changes Ever so slightly Daily and nightly In little ways When everything stays...

Anand says it is 1/4 at 3.5 TFLOPS https://www.anandtech.com/show/13923/the-amd-radeon-vii-review |

all media say 1:4...thats amazing... It is enough to grab your attention. How do the GPU work units do on Linux as compared to Windows? I have only compared the CPU ones. |

Good luck keeping it fed with MW work when you have an outage for hours everyday and not enough cache/work in progress for that downtime. |

Excellent point. I think I will wait for Navi and see how it does on dual-precision. Also, the power should be more reasonable. |

Anand says it is 1/4 at 3.5 TFLOPS all media say 1:4...thats amazing... That is flipping amazing! Although not as good as the rumoured 1: 2 but it’s still way better than 1:8 or anything Nvidia has to offer new at this price point. I will defiantly get my hands on one once the retail pricing is on MSRP. Everything stays But it still changes Ever so slightly Daily and nightly In little ways When everything stays...

Anand was the 1st article I read. I checked another later and it also said 1/4. Typically it is 1/16 then there was the rumor of 1/2 then 1/8 but 1/4 is still fantastic. Just like all projects, have a backup set to 0% resource share. Even the big projects go down unexpectedly or for maintenance. |

Well, if it's fp64 ratio is 1\4 then it's like 7970 all over again, and that was a brutal card back then with it's 1 TF of fp64. (Fp64 for 7970 was set at 1\4 ratio). |

We need a bigger limit allowed for WUs in progress for GPUs with this daily database issue. 600 doesn't cut it with multiple Tahiti based GPUs in 1 PC. |

They take only 2 minutes on my RX 570, and a Radeon VII would do them in only a few seconds. The server must be constantly tied up doing uploads and downloads. Probably 20X longer would be about right. Haven't they considered that already? |

You could reconfigure BOINC to say you have more GPUs than you actually do. Some SETI users do that since there is a weekly server maintenance. https://setiathome.berkeley.edu/top_hosts.php [63] NVIDIA GeForce GTX 1080 Ti (4095MB) driver: 410.66 [64] NVIDIA GeForce GTX 1070 (4095MB) driver: 415.27 [64] NVIDIA TITAN V (4095MB) driver: 410.57 OpenCL: 1.2 |

Good luck keeping it fed with MW work when you have an outage for hours everyday and not enough cache/work in progress for that downtime. Oh so I'm not the only one suffering from that issue! Yeah that really annoys me that I run out of work and can't access anything EVERY day :( Database down. There aren't any Radeon VII's to buy anyway. 0 availability and the temps quoted from testing are quite high. 110 degrees Celsius+. It's already baking in the southern hemisphere running muti GPU's through summer in a small room. I'd wait for the AIB boards to come out and let the dust settle.
