Valve Steam Deck LCD supplier FAQ

6 questions about this supply chain, answered from the records above.

Who makes Steam Deck LCD RAM?

iFixit's original LCD chip-ID guide identifies Micron MT62F1G32D4DR-031 WT:B LPDDR5 on its pictured board. That is a sample finding, not proof of exclusive sourcing across all Decks. See source [1].

Does Steam Deck LCD have 4GB or 16GB of RAM?

Valve specifies 16GB onboard LPDDR5 at 5500MT/s. The 4GB Micron description in iFixit's guide refers to a package rather than the system total. No package count or upgrade compatibility is inferred. See sources [1] and [2].

How does LCD RAM compare with Steam Deck OLED?

Both models have 16GB system RAM. Valve lists LCD at 5500MT/s and OLED at 6400MT/s. The pictured Micron packages are described as 4GB in the LCD guide and 8GB in the OLED guide; those are not total system capacities. See sources [1]–[4] and the related Steam Deck OLED supplier map.

Who makes the Steam Deck LCD processor?

Valve lists a 7nm AMD APU. iFixit identifies AMD/Valve 100-000000405 on its original board sample. This supports the processor role without assigning a foundry, packaging contractor or factory. See sources [1] and [2].

Who supplies the LCD panel and SSD?

These selected sources do not establish the sample's panel maker or main storage vendor. Analogix ANX7580 is a display-interface converter; Winbond W25Q128JW is serial NOR, not the main SSD. Sample capacity and manufacturing locations remain unknown.

Does this map cover refreshed LCD boards or OLED?

No. Its ten selected records belong to the original board pictured in the 2022 LCD guide. The OLED comparison uses separate sources and does not transfer OLED component vendors to LCD hardware. Later revisions need their own review.

Methodology & sources

Steam Deck LCD: RAM, processor and selected board evidence

Sources reviewed:

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.

    Sources: [2][3][1][4]

  • 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.

    Sources: [2][1]

  • 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.

Limitations (6)

  • The 2022 source and our October 20, 2026 review are different dates. This selected sample does not cover all LCD revisions, the refreshed 2023 LCD board, OLED boards or every storage configuration.
  • iFixit's 4GB Micron label describes a memory package. It is not the system's total RAM. No package count, RAM-upgrade support or exclusive memory contract is inferred.
  • The main SSD or eMMC supplier, storage-controller and NAND vendors, LCD panel, wireless module, battery-cell maker and final-assembly contractor remain unassigned. A display-interface converter is not a panel identification; serial NOR is not the main drive.
  • Tentative ITE and Monolithic Power Systems identifications are omitted. Some definite guide entries are also outside this deliberately selected map; omission does not show absence.
  • Foundry, packaging, component factories and manufacturing countries are unknown. Vendor names and headquarters do not locate a factory. Counts are selected records, not a full BOM, physical chip count, cost, purchasing volume or market share.
  • Original SuppliersMap cover art is an illustration, not a board photograph or evidence of installed parts. Evidence remains English in explicitly disclosed fallback locale pages.
