Pros & cons summary

Performance score	34.45	48.98
Recency	31 May 2021	13 October 2022
Maximum RAM amount	12 GB	48 GB
Chip lithography	7 nm	5 nm
Power consumption (TDP)	145 Watt	300 Watt

RX 6800M has 106.9% lower power consumption.

L40S, on the other hand, has a 42.2% higher aggregate performance score, an age advantage of 1 year, a 300% higher maximum VRAM amount, and a 40% more advanced lithography process.

The L40S is our recommended choice as it beats the Radeon RX 6800M in performance tests.

Be aware that Radeon RX 6800M is a notebook card while L40S is a workstation one.
