NVIDIA's GeForce RTX 50 "Blackwell" laptop GPUs have been spotted within the PCI ID repository, the RTX 5090, 5080, 5070, 5060 & 5050 series.
Several NVIDIA GeForce RTX 50 "Blackwell" Laptop GPUs Spotted At The PCI ID Repository
Out of nowhere, a new report has emerged suggesting that NVIDIA could be replacing the Blackwell GPU dies with Ada ones. While not officially confirmed, the PCI ID Repository lists "AD108M" against several RTX 50-series Max-Q GPUs for the mobile platform. The same can be seen on Techpowerup's database, where both GB206M and AD108M are mentioned against these Max-Q variants.
The AD108M doesn't officially exist in the Ada lineup and one can only find up to an AD107 die in the RTX 40 series GPUs. The Max-Q GPU series is usually found in thin and more power-efficient gaming laptops than the regular NVIDIA GPUs made for high-performance gaming laptops. NVIDIA had deployed both GPU types for different laptop categories in the previous Ada generation, but bringing the same Ada architecture to the newer RTX 50 series is odd.
Usually, you would find NVIDIA deploying faster GPUs on higher-end GPUs, but AD108M seems to be an entry-level GPU for RTX 5070 and other lower-class GPUs. However, since the AD108M made its first appearance, we don't know where it stands against regular and Max-Q GPUs. Techpowerup mentions that NVIDIA could use either the GB206M or AD108M on the RTX 50 series GPUs, while the PCI ID Repository only mentions the AD108M.
As per the table, there are four Max-Q RTX 50 series GPUs that are rumored to utilize the AD108M die:
- GeForce RTX 5090 Max-Q (GB203M)
- GeForce RTX 5080 Max-Q (GB203M)
- GeForce RTX 5070 Ti Max-Q (GB206M/AD108M)
- GeForce RTX 5070 Max-Q (GB206M/AD108M)
- GeForce RTX 5060 Max-Q (GB206M/AD108M)
- GeForce RTX 5050 Max-Q (GB206M/AD108M)
On the other hand, more powerful GPUs like the RTX 5090 Max-Q and RTX 5080 Max-Q will utilize the GB203M, which is a cut-down variant of the GB203 NVIDIA is going to use in the laptop RTX 5090 and RTX 5080 GPUs. While still early to conclude, it looks somewhat misleading to equip an older Ada architecture on the RTX 50 GPUs even if the performance is higher than their predecessors.
One thing to note in Techpowerup's database is that the architecture mentioned against GB206M is "Blackwell 2.0". Blackwell 2.0 is also mentioned against other dies such as GB205M, GB203M, GB202, GB203. Moreover, there are some new dies in the Blackwell lineup we haven't heard about. GB102 and GB102GL are reportedly just "Blackwell".
While we do know that the GB202 and GB203 are going to be utilized in the desktop RTX 5090 and RTX 5080 GPUs, we don't know why these are mentioned as "Blackwell 2" and not just Blackwell. I guess we will have to wait and see how different this newer Blackwell 2.0 is against Blackwell and what the AD108M brings to the table.
