the 2008 model Roadster -- how many of those are still running?
Nearly all? The average car is 12 years. Not because cars fail, but because new cars are registered.
A backup for something that has never happened before?
There has been a report every 10 years or so since the '60s or '70s that pointed out the most recent power outage was due to insufficient winterization.
So yes, this has happened before. Quite "often" (once a decade).
it would take a battery the size of Texas.
So the entire ERCOT exists for that one fab, and nothing else can run over it?
Or your simplification is a complete lie.
I can guess which it is.
Original Knights Corner (effectively a stepping of Larrabee) was ~60 cores, each 4-way threaded. Top-shelf Knights Landing parts were 72 cores.
Rumor was that the P54C design was re-imported back into Intel -- they had contracted out a re-implementation, I assume because they needed a fully synthesizable design rather than being tied to a specific die process. My old team had an FPGA socket 7 module that could run an instantiation of this code around 100MHz.
