In stark contrast to the RX 5700 XT, the Radeon VII is based on a complex MCM (multi-chip module) that has not just a 7 nm GPU die, but also four 32 Gbit HBM2 stacks, and a silicon interposer. It also has much steeper VRM requirements. Making matters worse is the now-obsolete “Vega” architecture it’s based on, which loses big time against “Navi” at performance/Watt. The future of AMD’s high-end VGA lineup is uncertain. Looking at the way “Navi” comes close to performance/Watt parity with NVIDIA on the RX 5700, AMD may be tempted to design a larger GPU die based on “Navi,” with a conventional GDDR6-based memory sub-system, to take another swing at NVIDIA’s high-end.
