For years? bzzzzzzt
There is no new "more efficient" node anticipated to BUILD miners on for years.
Is that hard for you to understand?
In fact, there is some question how much longer semiconductor node CAN continue to progress - GMO's over-optimistic projections to the contrary.
Intel and IBM in particular have both stated that "pure silicon" has reached the end of the road - IBM's current "next gen" process design work uses a MIXED silicon/germanium die while Intel has been quite mum on their plans for anything past their current 10nm node.
The old "new miner model every 6 months" routine died when ASIC mining hardware caught up with semiconductor state-of-the-art at the 14nm node (S9 and such), and CAN'T ever return.
Just noticed something I find a bit iffy about the S15/T15.
"exposed die" design on the chips.
Does anyone remember the massive FAIL issues associated with that concept on the Athlon Thunderbird/Palomino and same timeframe Pentium 3 generation CPUs that ALSO used an exposed die?
Probably less of an issue with the "glue-on" heatsinks Bitmain uses, but still a bit iffy - and definitely NOT THE NORM that Bitmain claims in that part of their "overview."
