With Nvidia GeForce RTX 3080 Ti laptop GPU and Intel Core i9-12900HK, gaming notebooks reach a new performance region. ComputerBase tested such a combination in comparison to GeForce RTX 3080 laptop GPU and Radeon RX 6800M as well as current gaming PC graphics cards.

New hardware for faster (gaming) notebooks
Intel and AMD presented new mobile high-end CPUs at CES 2022, and Nvidia gave OEMs the two graphics chips GeForce RTX 3080 Ti Laptop GPU and GeForce RTX 3070 Ti Laptop GPU as a new option at the upper performance end. The first systems with the new mobile Tis should be available from February 1st, the embargo on tests is already falling today.
Intel and Nvidia are getting ahead of their competitor AMD: It is not yet known in detail when its new Ryzen 6000 Mobile and Radeon RX 6000M will be available for purchase. If things are going the way they were a year ago, it will still be weeks, and for many OEMs even months.
This article focuses on the new flagship combination of Nvidia GeForce RTX 3080 Ti laptop GPU and Intel Core i9-12900HK in gaming use. At the same time, a CPU test of the Core i9-12900HK was published.
GeForce RTX 3080/3070 Ti Laptop GPU im Detail
A first glance at the maximum possible (aka fastest) configuration in the mobile GeForce RTX 3000 portfolio makes it clear what is behind the two new options at Nvidia:
With the GeForce RTX 3080 Ti Laptop GPU, the direction is clear: new mobile top model. The classification of the GeForce RTX 3070 Ti laptop GPU is again a bit more difficult, since with its positioning between RTX 3080 laptop GPU and RTX 3070 laptop GPU, especially considering the possible TGP bandwidths and without a unique memory selling point, it is just another of many configuration options with GA104 -GPU is.
- The GeForce RTX 3080 Ti laptop GPU takes the lead with more shaders, higher memory clocks and higher power consumption. However, this only applies as long as it is compared to an RTX 3080 laptop GPU with a maximum identical TGP.
- The GeForce RTX 3070 Ti laptop GPU, on the other hand, catches up with the GeForce RTX 3080 laptop GPU with more shaders, which, however, retains more shaders and can still be configured with even more TGP.
GeForce RTX 3080 Ti Laptop GPU: New GPU and higher TGP
The GeForce RTX 3080 Ti Laptop GPU relies on a whole new GPU: GA103M. This was also necessary in order to be able to make a difference in performance, because the GeForce RTX 3080 laptop GPU – like the GeForce RTX 3070 Ti for desktop PCs meanwhile – already used the full configuration of the GA104 GPU with 6,144 active shaders. The GA102 GPU used in the desktop PC for GeForce RTX 3080, 3080 Ti and 3090 and in the future also 3090 Ti is out of the question in the notebook.
Specifically, there are 7,424 ALUs that the GeForce RTX 3080 Ti laptop GPU can use with the GA103M GPU – 21 percent more than before, but still 28 percent less than the GeForce RTX 3080 Ti from the desktop PC. The new top configuration does not change the large performance difference between PC and notebook with GeForce RTX 3000 (and AMD Radeon RX 6000).
The GeForce RTX 3080 Ti laptop GPU is always combined with 16 GB GDDR6, which clocks at 16 Gbps as high as never before in the notebook – it remains to be seen whether this also applies to the small Max-Q versions. The GeForce RTX 3080 laptop GPU was still available with either 8 or 16 GB GDDR6 – although the OEM and not the customer usually made the choice.
The GeForce RTX 3080 Ti laptop GPU also increases the maximum power consumption: Instead of a fixed TGP of up to 150 watts and optionally up to a further 15 watts via Dynamic Boost 2.0 from the CPU budget, it is now up to 150 watts fixed TGP and up to an additional 25 watts via Dynamic Boost 2.0 from the CPU budget. The basis in the form of the maximum TGP remains the same, but notebook manufacturers can shift even more electrical power from the CPU to the GPU from the overall thermal budget if it suits.
GeForce RTX 3070 Ti Laptop GPU: GA104 with 5,888 ALUs like the 3070 FE
No new GPU is required for the performance upgrade of the mobile GeForce RTX 3070 Ti: It continues to use the GA104 GPU, but now with 5,888 instead of the previous 5,120 shaders (plus 15 percent). This corresponds to the configuration of the GeForce RTX 3070 for desktop PCs. At the same time, the maximum permissible power loss increases by 10 watts to 150 watts, whereby the TGP remains unchanged at 125 watts, while the maximum boost also increases from 15 to 25 watts. There is no higher memory clock: It stays at 14 Gbps and 8 GB GDDR6.
Both Tis with new generation Max-Q
Since the introduction of the GeForce RTX 3080 laptop GPUs, Nvidia no longer uses Max-Q to identify the most efficient models, but understands Max-Q as a generic term for features that all GPU configurations can offer. With the new Ti models come new features that only the new Tis can take advantage of.
“CPU Optimizer” requires a 12th generation Intel Core or AMD Ryzen 6000 Mobile and is exactly the basis for Nvidia raising Dynamic Boost 2.0 for the Tis from 15 to 25 watts.
“Rapid Core Scaling” should in turn be able to target the required number of GPU cores in professional applications and to be able to clock them higher instead of using the entire GPU – as long as the application can benefit from it. And a revised Battery Boost 2.0 should optimize performance, runtime, volume and picture quality when playing on battery power “with AI”.
No details on the configurations yet
Based on the key data, one thing is certain: The Nvidia GeForce RTX 3080 Ti laptop GPU will be the new fastest notebook graphics chip from Nvidia with a focus on gaming.
Even with this model and the GeForce RTX 3070 Ti laptop GPU, absolute comparisons to other graphics chips in the series or in alternative notebooks are only permissible if the maximum power loss permitted by the OEM is known. Like its predecessors, the new Tis allow for a wide range of power consumption and thus clock rates. It is not yet known which configurations are permitted. After the ComputerBase leak at the beginning of 2021, no clarification was possible to date, even privately.
A GeForce RTX 3080 Ti laptop GPU with 80 watts will definitely be slower than a GeForce RTX 3080 laptop GPU with 140 watts, possibly even than a GeForce RTX 3070 laptop GPU with 125 watts – those who are interested in a “Ti “ choose because they get the supposedly highest performance, it is important to be aware.
