All the more reason for them to go with the proven and far cheaper 14nm process node rather than 7nm (which Intel/MobilEye have had difficulties with as far as yields). https://www.techpowerup.com/248008/intel-at-least-5-years-be...

EDIT: Corrected below. MobilEye is using TSMC even though they're owned by Intel.

Intel/MobilEye is using TSMC 7nm for the EyeQ5 chip. There won't be any issues.

TSMC 7nm has already deployed the iPhone A12, the iPad A12x, and AMD's Radeon VII. Its mature and ready for mass production.

-------

The problem with Tesla's 14nm chip is that their capabilities are about to be leap-frogged by a commercial-off-the-shelf solution in just a year. Note that the EyeQ5 is sampling TODAY. MobilEye is aiming at cars being deployed with the thing for 2020.

Being potentially "leap frogged" in a couple years is only a problem if you're not planning on improving the chip in that time. Tesla is, in fact, planning on deploying an improved NN chip in 2 years (currently in development). They can use whatever process is available at that time.

And thank you for the correction about Intel/MobilEye using TSMC instead. Of course, anyone can use TSMC, so there's less vertical integration advantage for Intel/MobilEye than I had previously expected.

> Tesla is, in fact, planning on deploying an improved NN chip in 2 years (currently in development).

So Tesla is planning to spend another $100 to $200 Million on this project? For another chip? That's 10% of its remaining cash (Tesla only has $2.2 Billion left)

I'm not convinced that Tesla has the cash for these projects.

It's effectively coming out of the cash they were sending to Nvidia, so the effect on cash flow is actually positive.
More like all the more reason to source these chips from outside, I would argue
