Happy weekend @Sonia-Chen,
I am responding to several of your comments including:
- potential ASICs for Ethereum;
- Why Ethereum doesn’t scale with process nodes;
- Other information/FUD
1. Follow the Money – why small companies are eyeing Ethereum?
There’s saying in North America that encapsulates what you are pointing out here about multiple companies eyeing Ethereum ASIC’s … “Follow the money!”
To elaborate, Ethereum is the 2nd largest coin and represents over $700M USD in mining rewards. Currently there are only 2 serious contenders, AMD and Nvidia (and counting the weak E3 effort from Bitmain) and in theory, ASIC’s should have an overwhelming advantage over GPU’s. So multiple companies are relishing the opportunity to make bijillions of dollars by building Ethereum ASIC’s.
This is no different than how the market evolved with Bitcoin ASIC development. The path to Bitcoin success is littered with defunct companies, failed efforts and $100’s of millions of dollars of lost investments. I point you to this Bitcoin Wiki which shows:
- 28 ASIC’s going to market
- 10 ASIC’s being canceled
- About 50 ASIC’s announced but status is unknown
Ultimately only Bitmain, Canaan, Innosilicon/Holong and Whatsminer/Bitwei were successful. Even a giant with deep pockets and early access to 7nm nodes like GMO failed and withdrew from the market.
Ethereum is a much more complicated design and has the added cost burden of memory dependency (that I will post on a different thread one day).
As you well know, Ethereum ASIC’s are not easy to build. Even with a superstar designer like your CEO, Chen Min, Linzhi is at least 11 months (Aug 2018 to June 2019) into development with no tape-out date in sight. Assuming you are taping out at the end of July and the earliest you will see “super hot lot” samples is Nov. 7. Assuming another 2 weeks testing and qualification, you are another 80 days from production depending on fab availability. Oh and add another 2 weeks for OSAT (Outsourced Assembly & Test) which takes a little longer due to your use of an interposer and HBM stacked die.
Linzhi’s total project time is “guestimated” to be 19 months (i.e. August 2018 to Feburary 2020). That’s a far cry from your original presentation in September that was projecting April 2019 projection or 9 months (August 2018 to April 2019)
2. Semiconductor densities translate to non-linear improvements
Sonia, my friend, let’s debate using facts and empirical proof.
Your comment makes no sense as Ethereum is bottlenecked by memory bandwidth and not semiconductor logic; therefore, Ethereum hashrate will improve but only to the extent of available memory bandwidth (in other words, zero improvement, unless memory subsystem changes).
Case in point is the 7nm Radeon VII at 90MHs (1400c/1000m) compared to the 14nm Vega56 at 38MHs (1138c/800m). Performance increases by 2.4x which is the increase in memory bandwidth by 2x bus width (ie. 4096-bit vs 2048-bit) multiplied by 1.25 or 1000MHz/800MHz (increase in memory clock).
38 MHs x 4096/2048 x 1000/800 = 95MHs (close to the measured 90MHs)
To reiterate, moving from 14nm to 7nm and increasing the core clock by 23% (ie 1400MHz/1138MHz) DID NOT improve hashing performance beyond the increase in memory bandwidth.
3. ProgPOW and BSV conspiracy
What point are you trying to make about Kristy, Calvin and Craig? Are you suggesting that Bitcoin SV is going to adopt ProgPOW as their POW instead of SHA256 and nChain? ROFLMFAO
4. Help from friends
Send me a PM. We can help you with design of your ASIC and procurement of HBM memories. My team is from AMD and has extensive experience with HBM through 2 generations of Vega design and 8 generations of GPU design. Even the Beatles know that they need to get by “With a little help from my friends.”
