Great. Another feature to void your warranty straight from the factory.

Is there PCIe Gen 4 support in it ?

Very few actually overclock their desktop PCs, despite all the press that gets. A miniscule number will overclock a laptop where thermals and battery life are so important. And by overclocking Ryzen I think you have to give up its very smart power management - so, a complete waste of time.

12 cores to a laptop is promising

So this has about 8% lower single core than Tiger Lake-U, with a single core freq of 4.6Ghz vs Tiger Lake's 4.7 (2.1% lower freq).

And its multi-core is about 18% more than Tiger Lake-U despite having 100% more cores?

And this 35W part is going to compete with upcoming 35W TGL-H how?

Overclocking your laptop is dumb. The guys that designed it have very carefully balanced the power draw against the heat against performance. The last thing you need is to let the user go "LOLZ 5GHZ!" and warp their mobo in a week.

Geekbench heavily weights things like ML performance, for which Tiger Lake has dedicated accelerators. Multi-core scores for mobile CPUs are extremely dependent on system configuration, so I'd always encourage people not to read into them too much. In this specific intance, you can point to 4800U entries that have higher MC scores.
