Gainsborough APU leak points to Steam Deck 2: 50% CPU core bump and 24 GB LPDDR5 at 9600 MT/s

A leaked OpenBenchmarking entry for an AMD Gainsborough engineering sample shows 6 cores, 24 GB LPDDR5 at 9600 MT/s, and Furmark parity with today's Steam Deck at lower resolution.

TL;DR — three sentences

  • A leaked Gainsborough APU sample shows 6 cores / 12 threads at 2.4 GHz, a 50% CPU core bump over the current Steam Deck. (S1)
  • The sample carries 24 GB of LPDDR5 at 9600 MT/s, versus 16 GB of 6400 MT/s in today's device; the article flags 24 GB as a test configuration, not a confirmed shipping spec. (S1)
  • Furmark scored 3,508 on the Gainsborough sample at 1024 × 768 versus 3,323 on the current Steam Deck at 1280 × 800; the article frames the two as close rather than directly comparable. (S1)

No catalog match for this story — nothing is shown rather than inferring a match.

Reported by TechPowerUp on 2026-10-20. Summarized and analyzed by XAIPART Editorial.

What happened

An AMD Gainsborough APU has surfaced on OpenBenchmarking in an engineering-sample configuration, and TechPowerUp previously linked the same codename to Valve's potential Steam Deck 2 silicon path.S1

The leaked sample carries 6 CPU cores and 12 threads on a 2.4 GHz base clock, which it characterizes as a 50% increase over the cores in the current Steam Deck APU.S1

Memory configuration on the sample is 24 GB of LPDDR5 running at 9600 MT/s, compared with 16 GB of LPDDR5 at 6400 MT/s in today's device, while the article notes this 24 GB figure is a test configuration rather than a confirmed shipping spec.S1

In Furmark, the Gainsborough sample reached 3,508 points at 1024 × 768, versus 3,323 points for the current APU at 1280 × 800. The article frames the two as close rather than directly comparable because of the resolution delta and notes early drivers were used.S1

Background timeline

  1. - TechPowerUp reports an AMD Gainsborough APU engineering sample leaked on OpenBenchmarking, tied to the Steam Deck 2 rumor thread. [S1]
  2. - TechPowerUp previously identified the Gainsborough codename in an AMD driver drop and linked it to a potential Steam Deck 2 APU. [S1]

XAIPART take

Technical impact

The 50% core bump from 4 to 6 on the same Zen-family microarchitecture line, paired with LPDDR5 at 9600 MT/s, points to meaningful headroom for threaded game workloads and faster iGPU feed bandwidth than today's 6400 MT/s subsystem. [XAIPART analysis]

Even with early drivers, the Furmark parity at lower resolution is the more interesting signal: it suggests AMD and a partner are already validating a thermal and power envelope that is at least as efficient as the current Van Gogh part. [XAIPART analysis]

Market impact

For handheld gaming designs built around AMD APUs, a verified 6-core Gainsborough part with 9600 MT/s LPDDR5 would reset the BOM expectations on the memory side: 24 GB at that speed implies denser packages and tighter PCB signal-integrity work than the current 16 GB at 6400 MT/s. [XAIPART analysis]

For sourcing, expect a short beta-sample window before any retail APU is allocated; Valve and other OEMs will likely lock in memory vendor slots ahead of generic DIY availability. [XAIPART analysis]

Action

Design teams evaluating APU platforms for handheld or compact gaming form factors can park this codename on a watch list and plan validation around the 24 GB / 9600 MT/s LPDDR5 envelope. [XAIPART analysis]

Procurement should track AMD APU allocation notes and any partner memory vendor announcements around LPDDR5-9600 parts rather than committing long-lead orders against unverified sample specs. [XAIPART analysis]

XAIPART Forecast

XAIPART expects that, if a second OpenBenchmarking submission for the same Gainsborough silicon family does not appear with at least 24 GB of LPDDR5 at a sustained memory clock of 8400 MT/s or higher by 2027-03-31, this brief's design-in assumptions about the Gainsborough memory envelope are wrong. XAIPART analysis

Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. The shipping RAM capacity for any Steam Deck 2 product, the final APU SKU name, and the production release window are not disclosed by TechPowerUp; the leak is single-source and based on a pre-release engineering run.

Corrections: none at publication. This brief will be updated with a timestamp if the source corrects its report.
