Texas Instruments and Microchip: Am I a joke to you?

As far as I know none of them manufacture anything resembling a replacement for a Xeon, which is relevant to national security because those are uses in military applications.

I'm surprised to see on https://en.wikipedia.org/wiki/Microchip_Technology that Microchip does in fact have fabs. I thought it was fabless! Its fabs are in the US, but the assembly and test facilities are all across the Pacific.

Neither of them make high performance CPUs or GPUs
