Pros & cons summary

Performance score	0.40	7.47
Recency	17 April 2007	13 April 2021
Chip lithography	80 nm	7 nm
Power consumption (TDP)	40 Watt	45 Watt

8400 GS has 12.5% lower power consumption.

Vega 7, on the other hand, has a 1767.5% higher aggregate performance score, an age advantage of 13 years, and a 1042.9% more advanced lithography process.

The Radeon Vega 7 is our recommended choice as it beats the GeForce 8400 GS in performance tests.

Be aware that GeForce 8400 GS is a desktop card while Radeon Vega 7 is a notebook one.
