Pros & cons summary

Performance score	1.66	7.48
Recency	7 February 2012	13 April 2021
Chip lithography	40 nm	7 nm
Power consumption (TDP)	199 Watt	45 Watt

Vega 7 has a 350.6% higher aggregate performance score, an age advantage of 9 years, a 471.4% more advanced lithography process, and 342.2% lower power consumption.

The Radeon Vega 7 is our recommended choice as it beats the FirePro V3900 in performance tests.

Be aware that FirePro V3900 is a workstation card while Radeon Vega 7 is a notebook one.
