Video games are never a great comparison for raw compute performance. AMD's GCN based architectures have all been very good at compute relative to their graphics performance (recall how it was nearly impossible to find an MSRP AMD GPU during the mining boom). The Radeon VII is pretty ridiculous for compute, aided by the 1TB/s bandwidth due to it's HBM2 stacks.
