According to SSB, the 75th percentile for full-time system architects in private industry (the highest paid software developer category) in Norway in 2017 was $103K/year. This is close to the 50th percentile for all software engineers in US in 2017, which was $104K according to BLS. The 50th percentile for system architects in Norway was $87K.

Norway has a higher cost of living due to the 25% VAT, and because the national (non-developer) median salary is so high. Not to mention vehicle and gasoline taxes.
