One interesting parallel is Intel and AMD back in x86 1991, which is today the reason AMD is at all allowed to produce x86 without massive patent royalties to intel. [Asianometry](https://youtu.be/5oOk_KXbw6c) had a nice summery of it.

Nvidia is leaning more into data centres, but lack a CPU architecture or expertise. Intel is struggling financially, but have knowledge in iGPUs and a vast amount of patents.

They could have alot to give one another, and it's a massive win if it keeps intel afloat.
