News Jensen Huang Says Nvidia-Branded ARM CPUs Are a Possibility

I'd love to seem them get into the desktop / laptop CPU market. More competition benefits us all. They certainly have the resources to do it.

Remember Transmeta? They thought they could run ARM live translate based on CISC (x86) code. It's performance was horrid. Apple is now showing this.

You need a full recompile to squeeze the best performance. There are enough legacy programs that this creates all kinds of problems. (Especially video games)
 
That or Apple does a 180 and develops RISC-V chips.
Even if they went that route, it would be a very long time before anything shows up considering the bombshell announcement earlier in the year.

But then again they could just shove it on iOS platforms to serve as a test platform before migrating a mature product onto the desktop/laptop product stack.
