AMD's mobile GPU lineup, consisting of the Radeon RX 7000M and RX 7000S series, is based on the latest RDNA 3 graphics architecture. These lines include five SKUs, utilizing the "Navi 31" and "Navi 33" chips. The enthusiast-segment RX 7900M series, based on "Navi 31," and the RX 7600M series, based on "Navi 33," are the only options currently available in the RX 7000M series. However, AMD plans to fill the gap with the introduction of the RX 7800M series and RX 7700M series, both based on the "Navi 32" chip internally known as "Cuarzo Verde." While the GPU is designed to be integrated into gaming notebooks' mainboards, AMD provides reference-design MXM boards to OEMs. These boards were discovered in a public shipping manifest by harukaze5719 on Twitter.
The "Navi 32" package is similar in size to the compacted "Navi 31" package that powers the RX 7900M series. It features a physically smaller 5 nm GCD with 60 compute units, compared to the 96 on the "Navi 31" GCD. Additionally, it is surrounded by four 6 nm MCDs, providing 64 MB of Infinity Cache and a 256-bit GDDR6 memory bus. With these specifications, AMD has the flexibility to introduce not only the RX 7800M series and RX 7700M series SKUs, but also the RX 7900S series SKUs, targeting gaming-grade ultraportables. We can expect product announcements regarding these additions in Q1 2024, alongside some new desktop SKUs.
