Mostly lower power from what I understand. Do phones, tablets, and small laptops really need more than 4 cores? Probably not. So the only thing you get is lower power and maybe smaller chips (which can help with the economics).

If you only run one NodeJS app at a time, probably not

The obvious answer would be adding more CPU cores and surrounding circuitry. Especially on mobile it probably also makes a lot of sense to move more algorithms from software to hardware.

Well that would seem to call for adding specialized coprocessors or even FPGA's, not just more CPU cores.

I don't think AES or video decoding uses coprocessors or FPGAs, that's just implemented more or less like any other instruction.

If you're going complete coprocessor, you can do much more like Apple has done with their motion coprocessors or the secure enclave.

I do wish Intel would make a high TDP i7 with improved single thread performance. I would even be OK with a water cooler.

The lack of progress on thread perf is a huge problem.

There's a new laptop with a XEON processor:

If you look at the passmark thread performance charts E5 xeons are very low on the list: https://www.cpubenchmark.net/singleThread.html

E3 xeons (which are essentially i7s with ECC) score higher; But if you care about single thread perf then you get an i7-4790k which has been top of the list since 2014. Zero progress has been made since then.
