AMD Close to Launching Radeon RX 7800M Series Based on "Navi 32"
AMD's small Radeon RX 7000M and RX 7000S lines of mobile GPUs based on the latest RDNA 3 graphics architecture includes just five SKUs, spanning the "Navi 31" and "Navi 33" chips. The RX 7000M series only has enthusiast-segment RX 7900M series based on the "Navi 31," and the RX 7600M series based on the "Navi 33," leaving a vast gap that the company plans to fill with RX 7800M series and RX 7700M series SKUs based on the "Navi 32," referred to internally as "Cuarzo Verde." The GPU is meant to be hardwired onto the mainboards of gaming notebooks, however, AMD hands out reference-design MXM boards to OEMs. These were sniffed out in a public shipping manifest harukaze5719 on Twitter.
The "Navi 32" package is roughly similar in size to the compacted "Navi 31" package powering the RX 7900M series. It has a physically smaller 5 nm GCD with 60 compute units compared to the 96 on the "Navi 31" GCD; and is surrounded by four 6 nm MCDs, which give it 64 MB of Infinity Cache, and a 256-bit GDDR6 memory bus. With this, AMD has the option of not just carving out RX 7800M series and RX 7700M series SKUs, but also RX 7900S series SKUs within its segment aimed at gaming-grade ultraportables. We could see some product announcements to this effect Q1 2024, alongside some new desktop SKUs.
