AMD next-gen RDNA 3 architecture Navi 33 will have the same specifications as Navi 21, and use a 5nm process
Recently, news about the Navi 3x core of AMD’s next-generation RDNA 3 architecture began to circulate. According to Twitter user @KittyYYuko, the next-generation Navi 33 core will have the same specifications as the current flagship Navi 21 core. If the situation is true, it means that it has 80 CU computing units and 5120 stream processors and uses RDNA 3 architecture.

According to previous revelations, the Navi 31 core will use MCM multi-chip packaging, which means that the Navi 31 core will have two chiplets and a dual 80 CU computing unit design, reaching the specifications of 160 CU computing units and 10240 stream processors. In addition, the Navi 32 core between Navi 31 and Navi 33 will also use MCM multi-chip packaging, and it is expected that there will be 120-140 CU computing units. In addition, the Navi 3x core is likely to be manufactured using TSMC’s new process node, such as the 5nm process.
Previously, AMD has applied for a new patent for its next-generation GPU. It is an active chiplet with an integrated high-speed cache for bridging between multiple GPUs. It may be used on GPUs and APUs using the next-generation RDNA 3 architecture. AMD’s active bridge chip is mainly used for high-bandwidth interconnection between GPU chips. It will have a shared and unified last-level cache (LLC) that will provide synchronization signals for cross-chip communication. LLC refers to the L3 cache. In the current RDNA 2 architecture, the L3 cache is called Infinity Cache.
According to AMD’s plan, the new generation of Radeon RX series graphics cards will not be unveiled until the end of 2022 or early 2023. The opponent is NVIDIA GPUs that also use MCM multi-chip packaging technology, such as the rumored Lovelace architecture products. However, a series of recent supply shortages in the industry may affect the release of new products by various manufacturers. Previously, Twitter user @kopite7kimi once said that the Nvidia Ampere’s life will be extended at least until the end of next year.
