Steam Deck OLED: the six-nanometer Sephiroth APU and its HDR display

Published on May 18, 2026 | Translated from Spanish

Valve has released the Steam Deck OLED, a revised version of its handheld console that replaces the LCD screen with an HDR OLED panel. The most significant change is under the hood: the Sephiroth APU, manufactured on a 6nm process, which offers similar performance to the original model but with more efficient thermal management and longer battery life.

6nm Sephiroth APU: thermal efficiency without power leaps 🎮

The Sephiroth APU does not aim to surpass the previous 7nm Aerith in raw power. Its focus is different: by reducing the lithographic process to 6nm, the chip consumes less energy and dissipates less heat. This translates to fans spinning at lower speeds, the system staying cooler, and battery life extending up to 30% more in demanding titles. The HDR OLED screen, with vivid colors and deep blacks, complements the experience without straining the hardware.

Sephiroth doesn't summon meteors, but it cools your lap ❄️

Valve has slipped us an APU with a Final Fantasy villain's name that, instead of destroying the planet, focuses on not burning your thighs. The Steam Deck OLED is still a brick with grips, but at least now you won't need to put an external fan on it while playing Cyberpunk. Of course, the price remains that of a console that wants to be a PC, so your wallet will be the true Sephiroth of this story. 💸
