Problem is that the frequency is 1/2 of actual memory frequency, in spite of what the OP stated in this post - please see LClk in the AMD produced slide below. Using 3200Mhz RAM would give you DF bandwidth of 32Bytes * 800000 cycles = 25.6GBs is the maximum throughput that this design has to...

You even state in your answer "...and all this data transfer is repeated upwards of 100 times a second, ideally. That's a *lot* of inter-CCX traffic, and with the user closely observing every tiny little hitch, stutter and speck of input lag." What do you think the inter CCX traffic is running...

I am not saying that there is absolutely no impact, however the thread switching impact will be minimal. Games are not the only applications that are moderately multi threaded but you are not seeing performance drops in anything except gaming. It would seem that you didn't bother to actually...

@Kromaatikse You are showing your ignorance about ethernet networking. Gigabit, 10Gig, 100BaseT 10BaseT 2Base2 all use CSMA/CD (Carrier Sense Multiple Access with Collision Detection). That basically means that a device on the network just throws packets of data out addressed to another device...

I am not suggesting that Ryzen has no other issues. It is a completely new architecture. The apparently unprepared motherboard manufacturers scrambling to catch up with bios revisions would suggest that AMD were rather secretive during development. Core parking, SMT management and affinity is...

Guys, Has it occured to anyone that the CCX switching and slower than expected gaming performance is all connected by one root cause? The reason that we have been observing these anomalies have nothing to do with windows scheduling. It all gets down to the Data Fabric not having enough...
