According to reports, AMD will use Samsung's 4nm process node to develop low-end APUs and Radeon GPUs. The rumor comes from @Tech_Reve, who says AMD is expected to leverage Samsung's 4nm node to provide manufacturing support for some of its client products, including Ryzen APUs and Radeon GPUs. @Tech_Reve quoted "reliable sources" as saying that AMD is expected to rely more on Samsung's foundries in the future, which may be related to TSMC's fabs being completely booked due to huge demand in other areas such as artificial intelligence.
Although no specific product was mentioned, it is said that Samsung's 4nm node will be used for low-end Ryzen APU. AMD will launch a series of APU products this year and next, such as StrixPoint (microcontroller and chiplet) products, KrackenPoint and FireRange enthusiast chips. These 4nm chips are likely built for the handheld device market, which has become a hot gaming market. With Intel's Core Ultra chips entering this segment, we can expect AMD to make this segment more competitive with future APUs.
In addition, there is news that the next generation Radeon GPU will use Samsung’s 4nm node. Currently, AMD has only confirmed that its optimized RDNA3+ architecture will be used in the StrixPoint APU series. It is possible that we will see some standalone GPUs based on the same RDNA3+ architecture choose to adopt Samsung's 4nm node, while the RDNA4 series uses TSMC's 4nm process node. The AMD RDNA4 line itself is aimed at the entry-level and mainstream markets, so based on rumors, we're unlikely to see any high-end GPU products in the upcoming line.
Tech_Reve also mentioned before that AMD initially planned to produce APUs for Sony PS5 Pro gaming consoles, but later canceled it. The last major lineup that used Samsung nodes for gaming purposes was Nvidia's Ampere "GeForce RTX30" series, which was manufactured on the 8nm node, unlike the Ampere HPC lineup based on TSMC's 7nm node.
