ntel Panther Lake handheld performance is about to get interesting—so I tested Intel’s Core Ultra X9-388H at real handheld TDPs (17W and 25W). Here’s how Arc B390 stacks up against the Ryzen Z1 Extreme and Ryzen Z2 Extreme in benchmarks and actual games.
In this video, I put Intel’s “Panther Lake-class” Core Ultra X9-388H up against AMD’s Ryzen Z1 Extreme and Ryzen Z2 Extreme using realistic handheld power limits (17W and 25W) to see what Intel could deliver in a handheld form factor.
