I don't anticipate anyone using Oculink on devices that would have PCIe3.0 but know that bandwidth would only be slightly better than Thunderbolt 3/4 in that arena. ALSO, older cards will see diminishing returns as well between the two. So something to be mindful of.

I just wished Valve released the SteamDeck back in Q4 2019 alongside the RDNA-2 announcement. They could've stolen a lot of the "pandemic sales" from the Nintendo Switch. And it would've given them enough time to come up with the successor. Perhaps one built on AM5 with a powerful Zen4 CPU and a modest RDNA-3 iGPU. Then also release an eGPU Dock for it. Which basically Fast-Charges the unit, provides Active Cooling, speeds up the CPU, disables the iGPU, and runs the eGPU. Being consumer-friendly the dGPU in the unit would also be replaceable even with a behemoth sized card. It could just support AMD cards as they work as partners, but the community would be welcomed to make it compatible with Nvidia cards.

The only reason to not get your hopes up, is that Apple doesn't want to enter that space. There's antitrust. Besides they are the largest gaming corporation in history, because Apple makes the highest revenue and highest profits from Video Games. Yes, it's all from their AppStore but you wouldn't ruin a good thing for yourself would you? No, Apple isn't going to change. The silver lining is that Android follows Apple. So the upcoming QC 8g3 is going to be a beast. And we may see it in Windows tablets, laptops, and Mini PCs, and it might push big-AAA developers to transition from x86 to support ARM. So we might get a killer console eventually, not from Apple, not from Intel, but through the overall competition and likely from AMD and Qualcomm.
