The UK's most powerful (publicly known) supercomputer will use only AMD's Epyc CPUs (no GPUs or other accelerators):
Cray has landed a £79m deal to construct Blighty's 28-petaFLOPS Archer2 supercomputer, which will use second-generation AMD Epyc processors.
The contract was confirmed on Monday in an email from the British government's UK Research and Innovation (UKRI) organization to boffins.
The 750,000-ish-core supercomputer is significantly more powerful than its predecessor, the 2.6-petaFLOPS Cray XC30 Archer, which has 118,000 CPU cores inside racks of Intel Xeon E5 v2 processors. The UK's most powerful publicly known super, the 2.7-petaFLOPS 50,000-core Dell-EMC-Intel Cumulus, meanwhile, lives at the University of Cambridge.
The system includes "5,848 compute nodes, each with dual AMD Rome 64 core CPUs at 2.2GHz, for 748,544 cores in total and 1.57 PBytes of total system memory".
An older article explains the choice of a homogeneous, CPU-only system.

They'll be able to tally the Scotland independence votes in no time.
If only they'll manage to bring it up soon enough, otherwise the UKians may not have enough money to pay for it.

How many exaflops to create an immersive VR simulation of pre/non-Brexit UK?

I reckon a lot more than the £79m quoted value of this project.
Plus, the cost will be ongoing and raising with the amount of discrepancy between the cold (and foggy) reality and the virtual world.

Maybe so, but it will never be powerful enough to answer the question 'Why, after gaining Independence from a perceived abusive 300 year marriage with England, are the Scots so eager to join, what is in all but name, the Fourth Reich?'.(Really, as if being under the direct yoke of Germans is going to be any better than being under the yoke of the bastard offsping of the Germans..)
A warped mentality borne out of the abusive Union maybe?, one where it's been less a partnership of nations but more of a master-slave deal, with the English holding the whip hand, and after 300 years of that, that old slavey habit is a hard one to kick...maybe they hope the new massa will be better than the old massa..
I can see the apposite [robertburns.org] Burns poems about Rogues will then need an update in the event of Scottish Independence, something along the lines of s/English/EU/

Hold on there Braveheart -- if England, Wales and NI voted on Scottish independence, the vote would be decided on economic grounds and they'd be gone. The SNP are delusional. [theguardian.com] Scottish independence is in stark contrast to Catalonia or Brexit where it's net contributors trying to break away from unions.

You're off to a bad start there, I fucking hated that film...
Forget Wales and NI, they're irrelevant in that particular argument, economically and politically England is the strongest 'partner' in the UK, they decide. So, riddle me this, as the Scots are such a wearisome burden both economically and politically to the English (and they must be so, after all, it's all I ever hear the English say about the Scots..), why the fuck did what is ostensibly the English government go out of their way run so much 'better in the union' stuff the last time the Scots had a referendum on the subject of independence?.
Another question to ask, if Scotland is such a economic shithole as far as the English are concerned, why are there over half a million of them living north of the border?
Indeed, but not for the reasons that the link you pointed to implies, I'd be wary about believing 100% any economic data where they start talking about 'notional deficit'.
If you want delusional, how about a party whose whole raison d'être has been Scottish Independence, a party which should be standing by, letting Brexit happen then using that as a lever to break up the Union by bleating 'The Scots voted to remain' (conveniently forgetting that between 15-33% of their own supporters voted for Brexit), but instead, with delusions of grandeur, have tried by their machinations to try and prevent Brexit from happening, which has quite naturally been played up in the mainstream media and which has further alienated the English public from the Scots, yes, that's what they want I suppose, but when the Tories win the next UK general election (and they will) the Scots can wave goodbye to any notion that the UK Parliament will allow any sort of second referendum, and the English will have their revenge..popcorn time...
Personally, I've also been getting the popcorn in for when this one hits the mainstream media, have a look into the infiltration of the SNP by the 'woke' brigade and the mentally ill gender identity nutters, consider the religious divide in Scotland, consider that outwith the big two, the other biggie growth religion in Scotland is Islam, and consider that irrespective of whatever the churches/mosques say, the followers are not fond of our poor confused identisouls and the bullshit surrounding them. The fact that a party which stands a fighting chance of actually achieving what it's founders wanted is now fart-arsing around with the vote loser which is gender and identity politics is.....really fucking funny.
Catalonia is fun, isn't it?...well, obviously not for the Catalans, amazing how quiet the oh-so-democratic EU is on that subject..
Brexit is way more fun, destabilises the EU, destabilises the UK, possibly unites Ireland, possibly spanners NATO in the long run..
Net contibutors, eh?
It's funny that the EU wants to hang on to the UK..
It's funny that Spain wants to hang on to Catalonia..
It's funny that the England wants to hang on to Scotland..

As a consumer, I have a preference towards AMD thanks to their track record of maintaining sockets longer than Intel which enables a CPU only upgrade. I wonder if this could happen in high-performance computing too; in three years could new chips be used to bump up the performance or decrease power consumption?

https://en.wikipedia.org/wiki/Epyc#Third_generation_Epyc_(Milan) [wikipedia.org]
Three generations of Epyc (Zen, Zen 2, and Zen 3) will use the same socket: SP3. There was no Zen+ Epyc. Zen 4 Epyc will use a new socket, SP5, and you can count on it supporting DDR5 memory.
AFAIK, some of these Zen 3 and Zen 4 details have only been out for weeks or even days.
Threadripper is basically a high-performance computing line of CPUs, and identical to Epyc in many ways. 2 generations of Threadripper (Zen, Zen+) used the TR4 socket.
The situation might get a little confusing for the 3rd-gen Threadripper (Zen 2), with talk of a new TR4+ socket and new motherboards that will double the memory channels to 8 and adequately support up to 64 cores:
