Given that I wasnt surprised by the headlie Inhave to imagine that nvidia engineers were also well aware.

Nothing is perfect, everything has its failure conditions. The question is where do you choose to place the bar? Do you want your component to work at 60, 80, or 100C? Do you want it to work in high radiation environments? Do you want it to withstand pathological access patterns?

So in other words, there isnt a sufficent market for GPUs at double the $/GB RAM but are resilient to rowhammer attacks to justify manufacturing them.
