AMD vs Intel memory managemement

[Bryan O'Neal]

This is kinda new to me - Just so I am clear - unganged systems would
perform better if I have say - a caching system with limited threads each
pined to a specific core (we do this for processor cache anyway) while
ganged systems would perform better it I was spinning up a new thread for
each request and had a large amount (say 768GB) of ram running something
like PostgreSQL where threads are being fired up and down many thousands of
times a second but the data they seek is mostly in main memory.
