Let's see how good Ryzen 5 3550H and Core i5-9400H are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.
Advantages of AMD Ryzen 5 3550H
More powerful video core
Finer manufacturing process technology (12 vs 14 nm)
Less power hungry (35 vs 45 watts)
Advantages of Intel Core i5-9400H
1% faster in synthetic tests
Somewhat newer (30 April 2019 vs 6 January 2019)
Higher maximum frequency (4300 vs 3700 MHz)
Higher base frequency (2500 vs 2100 MHz)
HyperThreading (allows one physical CPU function as two logical ones. It increases performance, since while one logical CPU is waiting for data, the second may still do useful work)
Quick Sync (hardware acceleration of video encoding and decoding for Intel CPUs. Speeds up video encoding by times, but at the cost of somewhat lower quality)
AES-NI (Advanced Encryption Standard New Instructions - additional instructions for hardware acceleration of AES encryption and decryption)
TXT (Trusted Execution Technology - protects the system against viruses and rootkits residing in BIOS or in a boot sector)
vPro (a marketing umbrella term for several Intel technologies: AMT, TXT, EDB, VT, Anti-Theft and some others)
