For Better Computing, Liberate CPUs from Garbage Collection

Maybe I'm naive, but with multi-core CPUs, and parallel GCs, isn't it somehow the same? One core is mostly only used for GC, while the others do other things?

Edit: I guess they mention their chip itself can do it at a high level of parallelism, so that's probably one more advantage. But CPUs with additional slower cores and a lot more cores are in the works as well.

But the GC has to do it in a thread safe way which involves locking/synchronization. Otherwise you get nasty race conditions.

There's no need to lock or synchronize if you're working in a language with immutability and copy on write first class data structures.

Well, I can't read the paper, but how is their Chip not having those same issues?
