It's official: Nvidia is making the Nintendo Switch 2's processor
Details are still light at the moment, though.

After years of rumors and speculation, Nintendo has finally detailed the Switch 2. The new console comes with an upgraded processor developed by Nvidia, which Nintendo says enables gameplay at up to 4K at 60 frames per second (fps) in docked mode (contradicting previous rumors), or 1080p at up to 120 fps in handheld mode. The new console launches on June 5, and it comes with some significant upgrades compared to Nintendo's original handheld.
