This really wasn't a surprise, nVidia has seemed to be itching for a meaningful entry to the CPU market and when intel's CEO started undoing all and any future investment in the company it was clear everything was being setup for a sell off.

5 Billion is just a start but this is a gift for nVidia to eventually squire intel.

I think if Nvidia wanted to acquire Intel, they would acquire Intel.

Intel has never been so cheap relative to the kinds of IP assets that Nvidia values and probably will not be ever again if this and other investments keep it afloat.

Trump's FTC would not block.

You write with proper case-sensitivity for their titles which suggests some historic knowledge of the two. They have been very close partners on CPU+GPU for decades. This investment is not fundamentally changing that.

The current CEO is more like a CFO--cutting costs and eliminating waste. There are two exits from that: sell off, as you say, and re-investment in the products of most likely future profit. This could be a signal that the latter is the plan and that the competitive aspects of the nVidia-intel partnership will be sidelined for a while.
