Apples and oranges.

Browser applications generate a lot of garbage, there are many 
things going on in the background as browsers are high level 
development environments. There is no way you can use a 
freeze-the-world GC as the primary collection mechanism and be 
competitive. And most likely not using Go's GC either.

Not to mention that the memory consumption nearly doubles when 
you start to rely on the GC.

If writing a heavy "realtime" runtime using a run-of-the-mill GC 
was competitive, then people would do it to save money.
