I'd put money on an i7 960 from '08 beating a 2 vCPU GitHub Actions instance in raw compute.

My single threaded code runs about half as fast in Actions compared to my 3900x. They're not fast instances.

Your 3900x is from 2019. Op compared a CPU from 2008!

Single threaded performance just hasn't shifted that quickly in the interim.

In order for the quad core, eight thread 960 to be slower than an Actions instance, there'd need to have been an 8x uplift in single core performance since '08. It's been more like 2x.
