I bought my Dell XPS 15 in 2015 and it has one USB-C. I was hoping to upgrade my laptop to a RTX 2060, 2070 or 2080 laptop in 2019 but I'm also interested in having 4 USB-C and no USB-A at all (they are completely unnecessary because of adapters) and yet nothing is changing for years on the market:

  • 2015 - all laptops have 1 USB-C + 2-3 USB-A*
  • 2016 - all laptops have 1 USB-C + 2-3 USB-A*
  • 2017 - all laptops have 1 USB-C + 2-3 USB-A*
  • 2018 - all laptops have 1 USB-C + 2-3 USB-A*
  • 2019 (up to February) - all laptops have 1 USB-C + 2-3 USB-A*

* - maybe there are some exceptions but that's how it is roughly speaking for 99% of models. Only Macbook Pro and Dell 2-in-1 have 4 USB-C but both lack good GPU for work.

Is there some technical limitation that prevents manufacturers from inserting multiple USB-C on one laptop motherboard together with RTX?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.

    You're putting it "on hold" because it's "primarily opinion-based". But it's not: it's cold facts. I can re-state the question: "Is there some technical limitation that prevents manufacturers from inserting multiple USB-C on one laptop motherboard together with RTX?" If the answer is "current Intel motherboards allow only one USB-C per motherboard" then that answers my question because I will now know to wait for the next motherboard upgrade. I don't see any "opinion" here? – Jimsea Feb 11 at 16:21
  • You are presupposing that there is some technical reason when there almost certainly is not. The simple "cold facts" are that there are several orders of magnitude more USB-A devices than USB-C, that USB-A can (via a blue "enhanced" superspeed socket) support the same connections as USB-C, and that an A-to-C adaptor can make one appear as the other. The result is that it a manufacturer design problem, and that we cannot predict when or why manufacturers will sway from one socket to another, especially when one is so much more prevalent. Divining the future is inherently "opinion based". – Mokubai Feb 11 at 17:02
  • @Mokubai Sorry, I didn't actually know some of this, I'm just a plain "user". For example I genuinely suspect that present chipset for RTX and i7-8750H does not in fact support more than 1 USB-C and that Intel delivered such component to all laptop manufacturers and they are all stuck with no choice but to have exactly 1 USB-C and not more. Why do I think so? Because 2 other laptops without RTX have 4 USB-C so it in fact very much looks like a technical limitation of that particular chipset and motherboard... A-to-C adapter is not sufficient because there exist C-only devices and features. – Jimsea Feb 11 at 17:30

    You're asking us to speculate on behalf of manufacturers. There are certainly answers, but the manufacturers are the only reliable source for your answer. I'll put in my speculation : Power distribution, expectation to also have multiple A ports, expectation to also have HDMI, expectation to also have VGA, and the easy availability of C-to-multiport adapters. – Christopher Hostage Feb 11 at 17:34
  • From what I see approximately every other question on this website are such that they would qualify for "manufacturers" or "developers" to answer. Many are highly technical/detailed. I don't know if what I asked is "difficult" or "easy" to answer. How can I know? It seems like a question that many people have. And yet I'm receiving attacks and mockery (including from moderators) rather than a proper statement like "This question requires too significant research effort to be answered, I'm afraid no one will answer it. But maybe it's related to X or Y." - simple and professional. – Jimsea Feb 11 at 18:00
