Since the Sony PSP, we haven't really seen any convincingly good handheld gaming devices, until Nintendo gave it a shot with the Switch.
However, the Switch wasn't designed for the hardcore and more serious gamers who have moved beyond Super Mario. Thanks to that, it left a gap in the handheld gaming device market.
The Aya Neo is a startup project that is close to the end of its production already, after raising over $1,300,000 USD.
The Aya Neo, in it's current form, features a stunning 7-inch 1280 x 800 IPS display, a 10-25W AMD Ryzen 4500 CPU, 16 GB of LPDDR4x RAM, 3 USB Type-C ports for external devices, and over six hours of gaming battery life. Plus, there are a few options when it comes to internal storage as well.
As for the games, the Aya Neo will support all AAA Plus titled games, such as Cyberpunk 2077, Watch Dogs: Legion, Death Stranding, Assassin's Creed Valhalla, Destiny 2, Horizon Zero Dawn, etc. with good frame rates.
