Thunderbolt 4 - Is this even out yet or just a spec? Also, this is an Intel spec and Intel doesn't have PCIe 4.0 either so ...
eGPUs - Given that eGPUs only use 4 lanes, it seems like this is the best use case.
Ultra-high-speed external storage - There is only one PCIe 4.0 internal controller (Phison) at the moment (Samsung soon to join) and it isn't even very good. External storage generally lags behind internal storage so there is plenty of room to improve external storage within the bounds of PCIe 3.0.
Ultra-high-speed networking - PCIe 3.0 supports 10G ethernet as well as the latest wireless standards just fine. When I see 10G ethernet as common place, I'll reconsider the need here.
So it really just comes down to eGPUs. An alternate solution is to give them more lanes.
Exactly, I don`t have any reason to doubt Renoir`s efficiency improvements over Picasso. But Picasso was miles behind Intel on mobile efficiency. Hopefully the aforementioned power gating and decoupling Infinity Fabric from memory frequency will do the trick. If Renoir laptops get within 5% of Intel on battery life that would be a huge positive step for AMD.

Damn, you are right. That's a big miss IMO.Spunjji - Tuesday, January 7, 2020 - link
Why is not having PCIe 4.0 in a laptop a big miss? What would it be used for?Orange_Swan - Tuesday, January 7, 2020 - link
thunderbolt 4?, eGPUs, ultra-high-speed external storage & networking.BurntMyBacon - Wednesday, January 8, 2020 - link

Thunderbolt 4 is Intel only (TB3 is now open), but it also isn't any faster than 3...https://www.anandtech.com/tag/thunderbolt-4

Are you unable to read basic English or something? Perhaps go back to elementary school lol; it seems you need t more than you might think.oynaz - Wednesday, January 8, 2020 - link
It is in this very article. One of the first paragraphs.zamroni - Sunday, January 12, 2020 - link
hence, amd needs to add more pci lanes so manufacturers can put thunderbolt portsKorguz - Sunday, January 12, 2020 - link
try intel... arent they still below amd on total pcie lanes ???SolarBear28 - Monday, January 6, 2020 - link
