A similar effect played out in the HP3000 stack based CPU systems [1]

The stack was kept in memory, and the CPU only had "registers" for the 
top two, four or eight stack slots.

But reality was that all the way up until somewhere around the iapx286 
time range, RAM memory was faster than the CPU's it was attached to, so 
large register files on the CPU, or giant caches, were not needed.  The 
CPU was as fast as it was, and the RAM wasn't what was holding it back.  
After sometime around the 286 time range, CPU speed started greatly 
outpacing RAM speed and large on chip register files and caches (the 
bigger the better) came into play.
