ASUS has registered multiple Radeon RX 6900 SKUs with the EEC in Russia, raising the possibility of AMD announcing a cheaper alternative to the RX 6900 XT. The RX 6900 has been listed seven times, all with 16 GB of VRAM. If it is an error, then the listing should mean that ASUS is planning to release plenty of RX 6900 XT SKUs, at the very least.
