=== Source for scheduler size increase ===
  
It's increased to 64. I can't find the original Intel source, but its reflected here:

Also the instruction queue is increased from 2x20 to 2x25, but [citation needed] I guess, can't find it anymore :) --[[Special:Contributions/195.241.129.245|195.241.129.245]] 01:39, 18 July 2016 (EDT)

dubious intel statement on scheduler size

According to the Intel presentation slides, they have "Larger out-of-order scheduler" but what's not clear is what they meant by that. The ROB seems to remain at 192 entries. Scheduler is still at 60 entries. Or am I missing something? --At32Hz (talk) 16:20, 14 April 2016 (EDT)
