As usual, regardless of validity of leak interesting things to ponder.
Example:
12 core Zen 2.
What are the benefits of 12 core 12 threads?
There is a real cost to SMT, frequency and thermals.
Going without SMT could net higher performance and possibly be better than a slower 8c16t chip for games, or much better than 8c8t. Obviously would make apu bigger in size.
Cloud Scarlett could use 2 full chiplets for 16c16t, and run 2 Lockhart games on single apu when streaming to non 4k devices. Possibly wouldn't need same OS allocations etc.
This is where I have problems squaring it with apu size and if there's that many faulty chiplets to make this reasonable:
10c Lockhart ?
12c Anaconda
12 core sounds monstrously crazy if you assume it's 24 threads.
