The DC-DC PSU part can give or add some 10 percent .
The rest is the chip
So you are not exactly right
Show me real world numbers of Avalon 3 implementation at the same clock rates with better power efficiency than 15 percent.
I agree that using ready DC DC solution for 40-50 USD  will improve the power consumption a little bit  but then pricing of the miner will go up and this is pointless, as far the chip pricing is too high for what it is at the current market.
So at the end Avalon 3 chip is not going to have sales as it was with Avalon 2 gen chip.
It came out too late, then Avalon freeze the sales for 1 month (similar story to Gen1 mess) and now it is almost obsolete.
As usualy Avlalon chips are power hungry at high clock.
The only way would be to under clock the chip if it has a good pricing.
Only then there will be some market for it

Nope
