There's the global and Chinese versions of the Asus RoG 2 phone. Elite ( global ) 12GB/512GB, Ultimate ( global ) 12GB/1TB also "special" upgrade to the gpu. The other is the Strix edition ( or Tencent for the Chinese market but still works internationally ) 8GB/128GB. The main differences other than RAM/Storage is the global version have slightly better 4g and connectivity, Elite - LTE Cat18 - 211 Mbps UL, 1.2 Gbps DL and Ultiamte - LTE Cat20 - 316 Mbps UL, 2.0 Gbps DL and both have WiFi 802.11ad, 4x4 MIMO Vs the Strix/Tencent edition which comes with LTE Cat16 - 150Mbps UL, 1.0 Gbps DL and WiFi : 802.11ac, 2x2 MIMO. Also global comes with 30w charger Vs Chinese 18w charger but otherwise there all the same performing phone, Hope this clears it.
