AMD is expected to release the RX 7800 and RX 7700 in September. The cards which could possibly be the last RDNA 3 offerings allegedly feature the mid-range Navi 32 GPU. According to recent 3DMark Time Spy Graphics figures reported by leaker All_The_Watts, the RX 7800 and RX 7700 could outpace the RTX 4070 and RTX 4060 Ti respectively.
Apples to oranges. The RTX 4080 competitor is the RX 7900 XTX. The RTX 4070 Ti competitor is the RX 7900XT.
Logically the next thing to come out is the competitor to the RTX 4070, and a direct market replacement for the RX 6900 series and RX 6800XT. That should be the RX 7800.
If anything, it’s NVIDIA that has confused everyone by hiking up prices and the naming scheme.
