Anandtech mentions in their review [0] that AMD is shipping a scheduling driver for Windows, with a "game mode" that disables one of the CCDs to prevent games from experiencing high latencies due to threads being spread across dies. So, presumably: yeah, scheduling for this chip is hard and Linux is much better at heterogenous scheduling situations (having been used extensively in e.g. big.LITTLE and NUMA systems for many years certainly can't hurt)!
