it depends on what you take into account. if someone else pays the NREs to the foundry, i.e. a university agrees to collaborate and is offered access to a foundry for either free or at reduced rates, $250k-$500k comes off that amount, straight away.
Some interesting perspectives on this can be read about here:

The author is currently running a campaign on Crowd Supply:

Maybe you might have spoken to the people involved, either at FOSDEM or via Crowd Supply, but I suppose there might be some potential for collaboration or discussion.
The campaign itself won't get funded, it would seem, but like various others that went the same way, this is more a consequence of a number of different factors rather than it being a statement on the merits of making genuinely free and open silicon. FPGAs and the implemented CPUs are widely available and already in use amongst the target audiences, for instance.
However, pursuing such a campaign with a product that really needs to be done with "proper" silicon - needing higher frequencies and power/performance benefits, perhaps - might get more support, albeit from not quite the same audiences as the ones targeted in this campaign.

P.S. Still no progress from Crowd Supply on the latest update?
