Hub 4 is still an Intel Puma chip like the Hub 3, however the latency issues have largely been resolved in the Hub 3. The current huge increase in latency people are seeing on VM is down to congestion in some areas due to the current 'lockdown'.
The Hub 4 could help with this as it can bond more downstream channels but the latency problems are mostly down to upstream congestion.
If you're suffering from slow download speeds the Hub 4 might help, but if the problem is upload speeds it probably won't make a difference.

Not for all of us. My problems (and a number of others) started coinciding with a Hub 3.0 software update. I had the hub replaced (replacement was running 'old' firmware again) and it worked fine for 3 weeks until that too was upgraded, and the problem started to recur immediately. Both of these events were before the current lockdown started.
There appears to be an issue for some people running Hub 3.0 in modem mode experiencing very variable latency after an update to the latest firmware.
I'd love to try out a Hub 4.0 to see if it helps with my issues.
True that there has been a surge off latency problems since lockdown but I'm not hearing these problems with other providers, they seem to be handling this lockdown fine. But also true is that there a is quite of few of us on here that have had these issues since before lockdown. Mine started around December and have just got worse since lockdown.
