According to Nvidia boss Jen-Hsun Huang, next gen consoles are slower than current generation Max-Q laptops.
Speaking at GTC (via PC Gamer) last week, Huang outlined how gaming PCs tend to be on the larger side,
“Gaming requires powerful PCs and powerful PCs tend to be large. When we started working on gaming notebooks they were quite large so that the GPUs, which are very powerful, requires a lot of thermal and electricity, and therefore the systems tend to be quite large.”
You can see the slide with the claim of these Max-Q laptops being more powerful than next gen consoles around the 21:17 mark. The laptop in question contains an RTX 2080 Max-Q with the text below saying, “> Next Gen Console.” Nvidia is assuming here that a Max-Q 2080 (realistically as powerful as a desktop RTX 2070) will be more powerful than a next gen console. You can check out the full presentation below. Keep in mind, no announcements have been made regarding concrete specs for the next gen consoles.
