i5-1335U vs i5-13420H

I bought a Lenovo V15 G4 IRU laptop with 16 Gb RAM and 512 Gb SSD.
It should come with an i5-1335U but instead it came with an i5-13420H.
I want to understand the differences between those CPUs.
Some questions:

1. They went to market at the same time (Q1'23) and almost at same price (342 $ / 340 $) so I guess they must meet very different targets otherwise I would see no point in marketing both.
2. GPU: I read that the 1335U's Iris Xe (80EU) is better than 13420H's Intel UHD 13th (48EU) but I see that on 3DMark it looks like 13420H is faster so I do not understand (https://www.notebookcheck.net/i5-13420H-vs-i5-1335U_14729_14916.247596.0.html)
3. PassMark overall CPU Mark and many others see 13420H slightly faster in multicore and almost identical in single core (so I wonder why should someone buy 1335U at the same price?)
4. PCIe: 1335U PCIe version 4.0 with 20 lanes while 13420H PCIe version 5.0 with 28 lanes. Could you explain what does this impact?
5. TDP: hugely different, 1335U 15 W and 13420H 45 W. I am puzzled here: since technology is very similar (10 nm and equal project age) I guess efficiency is almost equal so it lools like the 13420H is only capable of dissipating more heat, just in case? But when you set power settings to consume less power they should consume more or less behave the same. So I guess there is no difference in battery life: the 13420H is only *able* to consume more. Am I missing something?

UserBenchmark: Intel Core i5-1335U vs i5-13420H

Impacts the drives you put inside and/or the GPU if there's a discrete GPU in play though most GPUs are only Gen4 anyway.

1335U 15 W and 13420H 45 W

U is ultra light / low power for ipad performance / duration whereas the H is high power for gaming / rendering type tasks

Two different beasts and target audiences. One is meant for leisure and the other is more productivity or gaming. I'm running a 12700H currently and base power draw of the system is ~45W but, if I engage the GPU with a game it will run full tilt ~180W w/ the RTX3060 at full speed.

Now, I'm waiting on the new AMD 300 series to come end of next month and ditch Intel completely as they're a dead end right now until the roll over to the new process with ARL and the 12/13/14th gen options are all the same stuff but higher prices with each release.

no sales tax / free shipping and you just put in your own drives/RAM which means not paying a MSFT tax for the OS you already bought as well
