Pros & cons summary

Performance score	1.44	7.46
Recency	17 March 2014	13 April 2021
Chip lithography	28 nm	7 nm
Power consumption (TDP)	15 Watt	45 Watt

GeForce 820A has 200% lower power consumption.

Vega 7, on the other hand, has a 418.1% higher aggregate performance score, an age advantage of 7 years, and a 300% more advanced lithography process.

The Radeon Vega 7 is our recommended choice as it beats the GeForce 820A in performance tests.

Be aware that GeForce 820A is a notebook card while Radeon Vega 7 is a desktop one.
