Laptop is the smallest worry for AMD at this point. Intel has allowed them to push TDP in server space by quite a bunch. Efficiency matters because Density matters to AMD. But removing themselves from any kind of 4S space, means density isn't even a worry unless they shooting for 2s 128c 1U systems at no to little performance loss. Clocks stay about even, maybe increase slightly or decrease slightly dependent on how the process develops or tweaks to uarch for increased clocks.
Then we look at Zen vs. Zen+. We didn't get a new Epyc even though we got a new TR. If anything the improvements to Zen+ should have worked more wonders on the efficiency table and allowed for dramatic increase in clocks on full spec'ed 32c EPYCs. Here we have no additional cores, maybe better efficiency, stagnate clocks, yet there is a Milan on the roadmap.
There is a balance here. But performance must increase. Otherwise if they they didn't make a Zen+ Epyc even thought they used the same tooling they would use for EPYC on TR2. Then they wouldn't be pushing out a new EPYC chip. All these can't be right. Either Zen 3 has higher IPC (enough to impact sales enough to do the validation), more cores, or increased clocks (with enough impact in sales to make it worth validation).
