Misleading Port Specification
Hi,
The Specifications of Inspiron 5410 2-in-1 (11th Generation Intel®Core™ i3-1125G4 Processor ) on the Documentation section is different from web Site, which is very confusing
The Site mentions USB 4.0 Type-C™ (full feature) but the document mentions USB 3.2 Gen 2 Type-C with Power Delivery/DisplayPort
I am very confused and not able to figure out what is the USB bandwidth 10/20/40 Gbps, if it is USB 4 ( otherwise Thunder Bold 3) with 40 Gbps.
Can this be clarified ? I connected with the Dell Customer care more than twice for the same above information, they couldn't answer clearly.

@Shibi If Dell’s own information is inconsistent, I’m not surprised that Dell Support can’t give you a reliable answer. But that is simply an “inconsistent” port specification. A “misleading” specification is something that is technically true but is presented in a way to get people to reach an incorrect conclusion.

@Shibi I don't know how you can get it reliably clarified. Dell Support does not always give reliable answers to questions like this, and if Dell's own documentation is inconsistent, that would make it even more difficult. But I just checked the Setup and Specifications of the regular Inspiron 5410 (not the 2-in-1) over here. On Page 6, it shows there are two possible versions of the USB-C port. One has a DP logo and one has a Thunderbolt log. And if you scroll down to Page 7 to read the descriptions of #5 and #6 from that diagram, you will find that one is USB-C and the other is TB4. So it looks like at least on the regular Inspiron 5410, the system is available in multiple configurations, which means you would have to check the specs of the exact system you configure in order to determine what you will get. The Inspiron 5410 2-in-1 might work the same way.

I did see that, but the 2 in 1 laptop Specification and Standard Laptop Specification of the same Series has different information
The Standard Laptop mentions One USB 3.2 Gen 2x2 , which is USB Type C with Display Port & Power delivery, I believe the bandwidth is 20 Gbps which is not confusion because it mentions 2x2. And also the Standard laptop Spec on both website and manual are in Sync.
If USB 4 mention on the Web Site for 2 in 1 laptop is for a purpose, but 2 in 1 laptop manual just mentions "One USB 3.2 Gen 2 Type-C with Power Delivery/ DisplayPort" in manual, not as "USB 3.2 Gen 2x2" But the question is, is it with 10 Gbps / 20 Gbps bandwidth ?
If it says USB 4 on the website for 2 in 1, I guess it could be 20 Gbps. Because it is from same product series. Can we make an assumption that it is 20 Gbps ?
And as per the USB 4 standards the bandwidth should must be 20 Gbps Ref.

@Shibi Unfortunately I can't confidently answer what would be safe to assume. But I personally would not expect to see the "USB 3.x 2x2" version of 20 Gbps get implemented very much at this point. That spec has existed for a while but wasn't widely implemented, partly because it would be impossible to use on docking stations because it would not leave any lanes for DisplayPort traffic. That's why the single-lane variation of 20 Gbps seems more promising, but I agree it's not very clear from the specs whether that's supported. But even there, the fact is that there are very few devices on the market that even use regular 3.x Gen 2 10 Gbps effectively. It's pretty much just SSDs and NBase-T Ethernet adapters (2.5 Gb, 5 Gb, 10 Gb). So realistically I'm not even sure that any products you'd want to use will actually be on the market before you want to replace the system anyway. If high speed I/O is a priority for you, I would recommend that you consider a laptop model that is confirmed to support Thunderbolt 4 instead.
