Yes, its a gaming laptop, and perhaps you're unaware but LLMs use GPUs, that's why he had focused some time on the task manager showing that the LLMs are actually running on the 4090
The large power brick is needed due to the huge power draw of the 4090, that's his point, while on battery, the laptop runs on the igpu.
The comparison is being made because of how popular high end nvidia cards are for LLMs, and so for tasks that need/rely on cuda cores, this is a very good comparison.
This is why nvidia is exceeded apple in its valuation, their data center GPUs are being used for LLMS and so everyone who's jumping on the AI bandwagon is buying nvidia products. For those people who don't own a data center, they need to consider what computer best allows them to work on AI, and the conventional wisdom is to use a computer with a high end nvidia gpu like the 4090 (though the razer us using the mobile version of the 4090)
Finally this is one of the highest spec'd laptops, in terms of cpu, gpu and ram, and for LLM based workflows, it did not beat out the Mac. If you think this was a poor comparison, please let me know of a laptop that is a better comparson and we can discuss
Why do you think a gaming laptop is not a good comparison, especially when its running high end cpu/gpu?
Edit: let me just add/clarify that gaming laptops are generally the most powerful/fastest built windows laptops outside of dedicated/specific workstation type laptops. Just because they have the word gaming in front of their title in no way invalidates the raw performance that are capable of (at a price, in dollars and heat).
