Steam Deck LCD: RAM, processor and selected board evidence

Sources reviewed: 2026-10-20

This independently written selection covers ten component roles on the original Steam Deck LCD board pictured in iFixit's February 15, 2022 chip-ID guide. The guide does not establish the sample's storage capacity, sales region, retail SKU or production batch. Valve's LCD specifications provide separate system context: a 7nm AMD APU and 16GB onboard LPDDR5 at 5500MT/s. A platform specification is not proof of every vendor in every unit. This is separate from Steam Deck OLED and later refreshed LCD boards.

• LCD vs OLED: both have 16GB, at different memory speeds

  Valve specifies 16GB LPDDR5 for both models: 5500MT/s for LCD and 6400MT/s for OLED. iFixit's LCD guide describes a 4GB Micron package, while its OLED guide describes an 8GB package. A package capacity and a system total answer different questions. Neither marking makes the whole system a 4GB or 8GB machine, proves every unit uses Micron, or establishes a supported RAM upgrade. The related Steam Deck OLED supplier map documents that separate sample.

• A flash chip, a storage option and a panel are different evidence

  Valve lists 64GB, 256GB and 512GB LCD storage configurations, but this chip-ID guide does not identify the pictured unit's capacity or main storage supplier. Winbond's serial NOR record must not be relabeled as its SSD. Similarly, the Analogix converter sits in the display-interface role; it does not name the LCD-panel maker. Those sourcing gaps stay visible instead of being filled from OLED hardware or another owner's device.

• Power and interface chips explain why a component map needs roles

  The selected charging, power-control, audio and interface records describe different jobs around the AMD processor. A Maxim battery charger does not identify the battery-cell manufacturer; O2Micro's card controller does not establish the supplier of a removable card. We preserve iFixit's Maxim Integrated attribution as written and leave physical manufacturing locations unknown.
