What makes this really interesting is that the system delivers a score significantly higher than what can be achieved with the NVIDIA GeForce RTX 2080 Ti. As the site reports, there are a lot of explanations here. The most exciting perhaps is that this could be AMD's "Big Navi". Guess we'll find out later this year.
The bigger question appears when we are trying to figure out what the GPU in this test really is. It could be an unreleased graphics in an external GPU enclosure, a Radeon running in CrossFire, or the Big Navi.
