I think you cannot compare all the listed cards.
SR5 does not work for 2.4 GHz only 5 GHz (high power wireless card), vice versa
SR2 works only for 2.4GHz (high power wireless card)
CM9 is 65mW and works for 2.4GHz and 5GHz.
You can try search option and find other users comments about listed wireless cards.
- MikroTik R52 2.4/5GHz will do turbo
- Sanao / EnGenius NMP-8602 (ETSI) 2.4 / 5GHz no turbo, some users have reported problems with these and routerboard - I only use them in PCs running ROS
- Sanao / EnGenius EL-5354 - 2.4GHz only will do turbo
I'm going to be trying the Sanao / EnGenius NMP-8601 soon but anyone elses expirence would be nice to know.
