Pros & cons summary

Performance score	16.79	19.79
Recency	6 May 2021	19 January 2022
Chip lithography	12 nm	6 nm
Power consumption (TDP)	40 Watt	53 Watt

T600 has 32.5% lower power consumption.

RX 6400, on the other hand, has a 17.9% higher aggregate performance score, an age advantage of 8 months, and a 100% more advanced lithography process.

The Radeon RX 6400 is our recommended choice as it beats the T600 in performance tests.

Be aware that T600 is a workstation graphics card while Radeon RX 6400 is a desktop one.
