x86 has been doing unified memory for integrated GPUs since at least 2015. It's not a new thing, see for example https://bit-tech.net/news/tech/cpus/amd-huma-heterogeneous-u...

The reason GDDR isn't typically used for system RAM is it's higher latency & more power hungry. Like, the GDDR6 memory on a typical discreet card uses more power than the an entire M1-powered Mac Mini power hungry.

Thanks, I haven't noticed the latency/power difference of GDDR memory.
