AMD Radeon RX 7900M high-end mobile Navi 31 GPU featuring 72 RDNA3 CUs set to launch on October 19

AMD Radeon RX 7900M to feature cut-down Navi 31

It is reported that AMD will unveil its high-end RDNA3 mobile GPU very soon. 

According to the latest information from Wccftech, AMD is preparing to unveil the Radeon RX 7900M mobile graphics card on October 19th, coinciding with the rumored release date of the Threadripper PRO 7000.

To provide context, AMD has thus far introduced mobile SKUs based on the Navi 33 architecture with the RX 7600M/S series, which have been relatively scarce in the gaming laptop market. Laptop manufacturers have primarily favored the RTX 4050/4060 series, and AMD had not shown much interest in competing with more powerful options until now. The Navi 32 GPU, boasting up to 60 Compute Units, appeared to be a promising choice for a laptop GPU, potentially slated for the RX 7800M series. However, recent reports suggest that AMD is shifting its focus towards the introduction of a more powerful Navi 31 architecture instead.

The upcoming RX 7900M is said to feature 72 Compute Units, indicating that it may not be based on the Navi 32 GPU. This lends credibility to the rumors about a smaller Navi 31 package, as observed in the RX 7900 GRE desktop model. The RX 7900M is expected to sport 4608 Stream Processors, more than double the core count of RX 7600M XT. The 72 CU configuration represents a decrease when compared to the RX 7900 GRE (80 CUs), RX 7900 XT (84 CUs), and RX 7900 XTX (96 CUs). This reduction in the number of GPU cores, approximately by 25%, appears to have been a crucial choice made to ensure that the GPU’s Total Graphics Power (TGP) remains below 175 watts, which stands as the upper limit for power consumption among laptop GPUs.

Previous rumors have indicated that the RX 7900M will feature a 256-bit memory bus, strongly suggesting a 16GB memory configuration (as 8GB is no longer sufficient for high-end SKUs). When comparing the released RX 7000M cards with the rumored RX 7900M, it becomes evident that there is a substantial gap between the Navi 31/33 cards. It is highly likely that AMD will eventually introduce the Navi 32 architecture, and one can only hope that the wait for its arrival will not be too lengthy.
