Till today, based on the public news, here is the summary of Grin ASIC miners:
|Miner||Vendor||Price($)||C31 Hashpower (GPS)||C31 $/GPS||C32 Hashpower (GPS)||Power (Watts)||Total Produced||Type||Efficiency (GPS/kW)||Delivery Date||C31 Life (Months)||C32 Life (Months)||Pre-Saled Number|
- The Innosilicon didn’t publish their total produced data
- Vidtoo didn’t publish their spec
There’s no way to give a ROI estimation without these. It’s appreciated if all ASIC miner vendors can provide these data trustworthy, to give a healthy mining ecosystem.
- Obelisk GRN1 Full Sale
[Updated at 4th May, 2019]:
Obelisk’s sale for their GRN1 was closed according to their info on website:
This sale will close on May 3, 2019. Obelisk expects to ship orders in October 2019.
And based on the public sales info, only about 101 GRN1 has been sold.
Note: “GRN1 Mini units count as 1/6th, and GRN1 Immersion units count as 2.”
I believe it’s quite far from a success sale for GRN1 - the 1st announced Grin ASIC miner. For 101 GRN1, it will increase C31 hash power for about 3.6k or only 5% (suppose no other ASIC miners) for current C31 hash power . We can imagine the main reason for this poor sales data is the short life period of GRN1. Because C31 will start phase out from 2020-01-15 (and completely phase out at 2020-08-11), and GRN1 “shipping estimated for October”, GRN1 only has about 10 month life period.
To summarize, C31-Only ASIC should be produced and delivered at the 1st time of Grin mainnet launching, otherwise, the C31/32 compatible ASIC solution (such as Innosilicon G32 miner and Vidtoo G1 miner) is the better choice for ASIC manufacturer. Hope Obelisk’s next generation GRN2 will have better performance and sales.
The good point of Obelisk’s GRN1 is their public promise of Sale capped at 2,500 units, and their transparent Order Counts, and of course their 5% donation promise to Grin development. At these aspects, both Innosilicon and Vidtoo are like a blackbox for community, nobody know how many G32 and G1 miners they will produce, and whether a big centralized Grin mining farm will grow up from these non-transparent ASIC miners in the near future.
