F1's level playing field rules have impacted computer chip choices

Nothing new here; it is widely known in the HPC world that F1 teams use AMD CPUs with all but one core per chiplet disabled in order to maximize the available memory bandwidth and clock frequency.

F1 CFD still has a major issue with big teams getting sweetheart deals from vendors for these customized chips, while low prestige teams are left buying "off the rack".

As with everything else F1 related, CFD in the sport is somewhat detached from the reality of product design. Rules should change to support either following industry trends more closely (ie cloud adoption), or lead the way with innovation on things like GPU-accelerated CFD which can then flow back out to the wider community.
