MagyarRumor | Nvidia RTX 4090 and RTX 4080 Laptop GPUs rated for 2 GHz+ boost and up to 200 W TGP including Dynamic Boost, RTX 4060 and RTX 4050 up to 95 W or 165 W each
So far, we've been seeing only sporadic references to Nvidia RTX 40 series mobile GPUs. Lenovo recently made the RTX 4050 Laptop GPU official with the introduction of the refreshed IdeaPad Pro 5 lineup. Now, information coming via Wccftech indicates the likely clocks, memory configurations, and TGP values of these cards.
We had previously speculated that the RTX 4090 Laptop GPU will be capped at a 175 W TGP, similar to the Ampere mobile generation, unlike the desktop version which can very well hit the 600 W mark at a higher power target. It looks like Nvidia will allow for an additional 25 W of Dynamic Boost power from the CPU for a maximum of 200 W TGP for the RTX 4090 and RTX 4080 Laptop GPUs.
It is now becoming clear that AD102 will remain confined to desktops, so the RTX 4090 is essentially a lower wattage desktop AD103 RTX 4080. If this information is true, we might not see any RTX 4090 or RTX 4080 Laptop GPU with an 80 W TGP. The Ampere-based RTX 3080 Ti Laptop GPU, on the other hand, offers a wide TGP range from 80 W to 175 W. Laptops such as the MSI Creator Z16P, for example, offer a 90 W RTX 3080 Ti.

| Base Clock | ~1.59 GHz | ~1.86 GHz | ~2.07 GHz | ? | ~2.37 GHz |
| Boost Clock | ~2.04 GHz | ~2.28 GHz | ~2.17 GHz | ? | ~2.37 GHz |
| VRAM | 16 GB | 12 GB | 8 GB | 8 GB | 6 GB |
| TGP | 150 – 175 W (+25 W Dynamic Boost) | 150 – 175 W (+25 W Dynamic Boost) | 115 – 140 W (+25 W Dynamic Boost) | 115 – 140 W (+25 W Dynamic Boost) or 85 W (+10 W Dynamic Boost) |
115 – 140 W (+25 W Dynamic Boost) or 85 W (+10 W Dynamic Boost) |
The RTX 4070 and RTX 4060 both feature 8 GB VRAM but different GPU dies. The RTX 4070 and RTX 4060 Laptop GPUs are said to be operable between 115 and 140 W TGP, but the publication notes that the RTX 4060 will also be configurable at 85 W. The RTX 3070 Ti Laptop GPU does offer an 80 W configuration with a boost clock of 1,035 MHz, but it looks like Nvidia may not offer this power option this time around for the RTX 4070 Laptop GPU.
Although Lenovo made the RTX 4050 Laptop GPU official in a way, no specs were divulged during the IdeaPad Pro 5 series launch. It is likely that the RTX 4050 will also sport 6 GB VRAM like the unreleased RTX 3050 6 GB and will offer a similar TGP range as the RTX 4060 Laptop GPU.
Nvidia is expected to make Ada mobile official during its CES 2023 keynote on Jan 3. It remains to be seen if the company will introduce any changes to the current Max-Q technology stack, though features such as DLSS 3 are expected to be trumpeted a lot.
We also expect Nvidia to introduce more desktop RTX 40 cards, such as the “unlaunched” RTX 4080 12 GB which is expected to be rechristened as the RTX 4070 Ti.
