Nvidia has a sprawling APU family in the Tegra series of ARM APUs, that span machines from the original Jetson boards and the Nintendo Switch all the way to the GB10 that powers the DGX Spark and the robotics-targeted Thor.
In performance even the aging Zen2 would demolish the best Tegra you could get at the time.
You should note that the Switch, the only major handheld console for the last 10 years, is the only one using a Tegra.
And from everything I've heard Nvidia is a garbage hardware partner who you absolutely don't want to base your entire business on because they will screw you. The consoles all use custom AMD SOCs, if you're going to that deep level of partnering you'd want a partner who isn't out to stab you.
