AMD Radeon RX 7900M features navi 31 MCM technology, 72 CUs, 16 GB memory
Previously, there were speculations that AMD would unveil the Ryzen Threadripper PRO 7000 processor on October 19th. The latest reports suggest that, in addition to the next-generation Ryzen Threadripper, they will also introduce the Radeon RX 7900M mobile graphics card.
This intel comes from Wccftech, noting that AMD’s current RDNA 3 architecture GPUs for mobile platforms predominantly rely on various derivatives of the Navi 33. The Radeon RX 7700/7600 both utilize this GPU, targeting primarily the entry-level and mainstream markets. This GPU boasts up to 32 CU clusters, amassing a total of 2048 SP. In terms of specifications, it appears comparable to the RTX 4050/4060, which employs the AD107. However, the competitor’s GPU seems to be more favored in the laptop market, and AMD has shown limited recent expansion in this domain.
Considering the scale of AMD’s current generation GPUs, the Navi 32, with a maximum of 60 CU clusters, seems more apt for the laptop market. Yet, AMD has chosen to go grander. The rumored RX 7900M is said to possess 72 CU clusters, totaling 4608 SP. It’s evident that it isn’t based on the Navi 32 but likely the larger Navi 31. This core specification surpasses the desktop RX 7800XT by 20% and trails the RX 7900GRE by 10%. It incorporates four MCDs, indicating a 256-bit memory bandwidth, and is paired with 16GB of memory. This places it on par, in terms of memory, with the top-tier competitor’s RTX 4090 laptop GPU.
Given its reduced scale, the RX 7900M’s TGP will inevitably be lower than its desktop counterpart. It’s believed that this graphics card’s TGP stands at 160W, which can be boosted to 200W through the SmartShift technology. Of course, its frequency will assuredly be notably lower than the desktop version, with the maximum dynamic frequency potentially falling below 2.0GHz.
Inferred from product naming conventions, there seems to be room for two models between the AMD Radeon RX 7900M and RX 7700S. These slots are likely reserved for the Navi 32 GPU, leaving us to wonder when AMD might unveil it.
