Passmark

This is the most ubiquitous GPU benchmark. It gives the graphics card a thorough evaluation under various types of load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities.

Pros & cons summary

Performance score	32.26	29.86
Recency	4 January 2022	21 March 2023
Maximum RAM amount	4 GB	24 GB
Chip lithography	7 nm	5 nm
Power consumption (TDP)	80 Watt	72 Watt

RX 6600S has a 8% higher aggregate performance score.

L4, on the other hand, has an age advantage of 1 year, a 500% higher maximum VRAM amount, a 40% more advanced lithography process, and 11.1% lower power consumption.

Given the minimal performance differences, no clear winner can be declared between Radeon RX 6600S and L4.

Be aware that Radeon RX 6600S is a notebook card while L4 is a workstation one.
