Let's see how good Core i9-9980XE and Ryzen 9 3900X are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.
Advantages of Intel Core i9-9980XE
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)
AES-NI (Advanced Encryption Standard New Instructions - additional instructions for hardware acceleration of AES encryption and decryption)
TSX-NI (Transactional Synchronization Extensions New Instructions - hardware acceleration of multithreaded calculations for Intel CPUs)
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)
vPro (a marketing umbrella term for several Intel technologies: AMT, TXT, EDB, VT, Anti-Theft and some others)
Advantages of AMD Ryzen 9 3900X
9.5% faster in synthetic tests
Cheaper ($499 vs $1979)
Finer manufacturing process technology (7 vs 14 nm)
Less power hungry (125 vs 165 watts)
