AMD is set to maintain the RDNA3+ architecture for its APU (Accelerated Processing Unit) graphics until at least 2027. This decision is attributed to AMD's partnership with Samsung on the Exynos project, which has limited the company's ability to make significant architectural updates to its APU graphics. Consequently, AMD will extend the use of the RDNA3+ architecture, initially expected to debut in the forthcoming AMD Zen 5 "Strix Point" APUs, which are anticipated to launch in mid-2024. The RDNA 3+ graphics architecture, also referred to as GFX115X or RDNA 3.5 in technical circles, has been under development for some time and has previously been identified in Linux patches. This architecture is essentially an optimization of the existing RDNA 3 series, currently employed in Radeon RX 7000 GPUs and Ryzen 7040/8040 APUs.
While specific details about the RDNA 3+ architecture have not been disclosed by AMD, it is confirmed that the upcoming Strix Point APUs will utilize this technology. These APUs are expected to feature up to 16 RDNA 3+ compute units on a single chip, with the potential for the entire chiplet to encompass as many as 40 RDNA 3+ compute units. This represents a notable enhancement in computing performance compared to AMD's current Phoenix and Hawk Point APU offerings.
