Yep
4 cores in a compute complex (CCX) still.
Zen 2 has double L3 Cache per CCX though ! (16MB instead of 8MB)

CCX size @ Anandtech
Correct, those 4 cores already share the same single L3 cache. Only CPU to GPU communication goes over Infinity Fabric in APUs. Just remember that 2x00G APUs utilize Zen 1 cores. The upcoming 3x00G APUs utilize Zen 1 + cores (same as 2700x). Next years 4x00G APUs should utilize Zen 2 cores. Not known yet if these Zen2 APU will be on its own 4/8 core chiplet with a GPU chiplet or a monolithic Zen2+ GPU die. If next gen APUs have more than 4 cores they will like this patch.
You wont. But anyone with a multiple CCX configuration will see more predictable results with less inter CCX L3 ping pong. It should lift min fps some in games.
