Follow-up: Just learned that so far AM5 is actually a regression compared to AM4[0]. The best they can give is exactly 16 usable lanes (4 of total 20 reserved for chipset). Zen4c models only give you 10. Between this and Pluton I'm quickly losing interest in AM5...
[0]: OK, total bandwidth is still obviously up because we have gained a PCIe generation but still I'd have expected available lane-count to not drop.
- wtallis 2y agoAM5 is not a regression from AM4; it adds four more PCIe lanes. The laptop chips repackaged for the desktop socket don't have as many lanes, because laptop chips don't need that much IO.
- 3np 2y agoI'm talking about the AM5 desktop APU options (including announced PRO APUs), not the platform itself or laptop SKUs.
