Cinebench R20
Blender BMW Benchmark
CPU-based performance from the X570 Phantom Gaming-ITX/TB3 is as good as we have seen from other X570 motherboards. Clearly size is no problem for this contender from ASRock.
We hit the boost clocks expected of our Ryzen 9 3900X and the sustained all-core frequency under loads such as Cinebench R20 and Blender was in the order of 4.05GHz.
