x86

if intel would make x86 an open standard or open source 

then that could brake the advance of arm 

in the server and supercomputing market 

by making different companies use x86 instead of arm 

intel risks loosing market share to other companies 

if other companies use their own x86 chips 

but intel could still make money from that 

by producing those chips from other companies in intel fabs 

many open standards and even open source 

are used in most industries 

in the car industry wheel and tire specifications 

are basically open standards or even open source 

different tools that workers use such as hammers and screw drivers 

are basically open standards or open source 

and many chemical recipes such as cement are open source 

and so on 

and if usa would worry 

that chinese companies could use x86 to make china stronger 

then it's wise to understand 

that it's not whether chinese companies has access to x86 or arm 

that enables china to become stronger in chip production 

instead it's the availability of chip production technology 

and since the latest commercial chip production technologies 

are owned by american, european and asian companies 

and not by chinese companies 

which could easily be regulated by trade deals 

and counter espionage 

historically cpus have been designed to have more and more cores 

which indicates that cpu cores won't become more complex 

instead cpu cores will rather become less complex  

in order to fit more cores in a chip 

and by looking at the vast amount of open source chip core designs available on open source sites 

indicates that it's relatively easy to design chip cores 

and would thereby be relatively easy for chinese companies 

to design their own chip cores 

the difficulty for chinese companies would instead be acquiring 

the latest commercial chip production technologies
