It should be adequate for a non-entry level laptop.
One of the fairly accurate Apple leakers, Jon Prosser, has said that one of his proven sources has informed him that the leak is legit.
That dovetails with my own experiences. I installed tomb raider on my m1 air, and while it was playable i was not impressed with its graphical abilities. The m1 is great for integrated graphics, but not on par with dedicated graphics. CPU-wise it is the fastest computer I have though, noticeably faster than the i5 9600K in my desktop.
>The first Apple-built GPU for a Mac is significantly faster than any integrated GPU we’ve been able to get our hands on, and will no doubt set a new high bar for GPU performance in a laptop. Based on Apple’s own die shots, it’s clear that they spent a sizable portion of the M1’s die on the GPU and associated hardware, and the payoff is a GPU that can rival even low-end discrete GPUs.
