Intel show off 28 core processor at 5ghz

There's been a lot of criticism of what is just a publicity stunt but I quite like it for how ridiculous it is:

Although Intel is promising a Q4 release for this processor it seems unlikely, what it appears they've done is take their existing $10,000 Xeon platinum 20 core processor which normally tops out at 3.2Ghz with all cores running, fitted a monster cooling system to it (even the VRM array needs a quad set of fans) with a beefy power delivery system to allow all 28 cores to hit 5Ghz.

AMD also showed their own monster with Threadripper 2 which is likely to be released soon with 32 cores instead of the 16 of the original:

This also seems a bit pointless as the large number of cores on the original Threadripper could cause problems with some applications and there's not much that can support such a large core count beyond high levels of virtualisation.

I was reading about this as well, the intel processor was a bit of a joke, not entirely sure they were trying to prove.

I'm probably being a bit dumb, but are these processors targeted at the consumer market in anyway or are they just for Commercial/Enterprise use?
Even for a gaming PC wouldn't there be other components that would choke the PC before the processor

I can't see any function for these processors for gaming PC's or consumers apart from for boasting, it's easy enough for both companies to effectively rebadge their server processors. I don't see what Intel was doing is any worse than AMD as both are pointless products aimed at getting headlines.

The problem with multi core processing is that the software has to be well written to take advantage of multiple threads, most applications tend to be optimised for around four cores and even those that claim to have good multi-threaded support will only support a small number of cores. I have an elderly hex core i7 3930K which with hyperthreading has 12 threads on offer and regularly even with multithreaded optimised applications such as video encoding there's cores sitting idle. AMD's original 16 core threadripper's game mode actually reduces the core count by half to improve performance since there's no need for the additional cores but even in high performance modelling applications and similar at work we don't use more than ten core processors and even then CPU utilisation is low.

Virtualisation is where the high core counts come in handy for running a large number of high performance servers but that's far beyond any consumer is going to need and even much lower core count processors can do the job for simpler consumer use.
