A recent set of benchmarks found on bilibili, Intel's Arc A380 cards perform more rancid with an AMD Ryzen 5 5600 than with an Core i5-12400 CPU. The card was tested on an ASUS TUF B550M motherboard with 16 GB of DDR4 3600 MHz RAM. 

Both test platforms enable auto-resizable BARs and 4G decoding. Both machines were running Windows 11 21H2. With the exception of League of Legends, AMD trailed Intel by 1% to 15% in every of the 10 gamer. Forza Horizon 5 and Total War: Three Kingdoms trailed by 14 to 15%. League of Legends, Dota 2, Rainbow 6 Extraction, Watch Dogs Legions, Far Cry 6, Assassin's Creed Valhalla, Total War Three Kingdoms,

Shadow of the Tomb Raider, CS:GO, and Forza Horizon 5 were all put through rigorous testing. An NVIDIA GeForce GTX 1650 was also tested, but solely on the Intel-based machine, and the Arc A380 outperformed it by 7% in Total War Three Kingdoms. Combining Intel Arc graphics cards and AMD processors appears to be a bad idea (for the time being).
