Although you can get full-on desktop GPUs in laptops, you'll run into thermal issues pretty quickly. To deal with this issue, along with battery life, Nvidia has developed its so-called 'Max-Q' GPUs, which are essentially the standard desktop GPUs but underclocked and undervolted quite significantly to make them suitable for use in notebooks. Up until now, the RTX 2080 Max-Q is the top-end of the Max-Q graphics cards, but it looks like the RTX 2080 Super Max-Q might be just across the horizon.
The information comes courtesy of hardware leaker Apisak on Twitter, who tweeted a link to a Geekbench submission for a notebook that carries the GPU in question.
Sadly, the submission by itself doesn't give us a lot of information to go by, but with the knowledge of how Max-Q works, we can get quite a long way.
Nevertheless, the details that we do know are that the RTX 2080 Super Max-Q comes with a full 48 compute units like the desktop-class RTX 2080 Super, meaning it carries the full 3072 CUDA core count. The maximum frequency of the Max-Q variant sits at 1.23 GHz in this particular notebook, but that could be subject to change. The GPU is surrounded by 8 GB of GDDR6 memory that communicates over a 256-bit memory interface, and although we don't know the memory clocks, chances are that it runs at a slightly lower clock than the desktop card, at least if the RTX 2080 Max-Q's specifications are anything to go by. We would also expect to see the full 48 RT cores.
As far as performance goes, you can expect to see quite a big hit compared to the desktop card, but a small upgrade compared to the non-Super RTX 2080 Max-Q (either in the 80w or 90w variant). Nevertheless, performance in a laptop will strongly depend on the notebook's ability to dissipate heat and thus keep the GPU operating at a high boost clock.
