AMD Radeon RX 7800, RX 7700, and RX 7600 tipped for a June 2023 launch
While Nvidia and AMD's high-end offerings have been out and about since late last year, they only cater to a small market niche. The real moneymakers are mid-range offerings, usually unveiled sometime after their flagship counterparts. Nvidia's GeForce RTX 4070 will launch in three variants sometime in April. Those looking for AMD alternatives may have to wait a bit longer.
A report from MyDrivers (H/T Wccftech) says the remaining RDNA 3 desktop lineup, Radeon RX 7800, RX 7700, and RX 7600 (and their XT variants), could be launched sometime around the Chinese 618 festival. It is one of China's largest e-commerce events which happens on June 18 annually. A global launch should follow suit at around the same time. On the other hand, entry-level offerings such as the RX 7500 XT and RX 7400 XT might not be introduced until next year.
Outside of a massive leak by Angstronomics, little is known about what Navi 32 and Navi 33 have in store. The former supposedly uses Navi 31's multi-die design with four MCDs and one GCD, while the latter will stick with a monolithic die. The recently unveiled Radeon RX 7700S, 7600S and 7600M gave us a brief glimpse into Navi 33's power, although its desktop variants will almost certainly perform better due to relaxed thermal constraints and a larger die size.
