I got a esxi host that has an dual port hab connected to 2 FC switches
on one of the FC switches, it shows 8Gbps
on another it shows 4Gbps
Is it the difference in modules used?

sfpshow -all | grep Trans
(Substitute -all for the slot/port (or just port) in question)
Run the above from both switches.
On one, I would suspect a return of 200,400,800_MB/s. (the connection showing 8).
Does the other also show this? If not, the SFP is suspect. (It's either a 4G SFP, or, its a faulty 8G SFP)
This assumes both switches are identical...

you can try to configure a fixed 8Gbps speed with the command
portcfgspeed <portnumber> 8
or view port settings with portcfgshow <portnumber>
