RTX 5090 EOL, PS6 AI Crisis, Steam Deck 2 Specs, Zen 6 AM5 APU Leak | The Phawx | Broken Silicon 383

Summary

Tom, host of Broken Silicon, and Cary “The Phawx” discuss handheld hardware, console strategy, GPU technologies, and how AI tools could alter game development and preservation. Many hardware details are leaks or forecasts rather than confirmed specifications.

Handheld Performance and Low-Power Tuning

• The Phawx focuses on PC and Android handhelds, especially extracting more performance per watt by tuning CPU, GPU, memory, and other APU clocks.
• He argues that power-management behavior—not simply Windows “bloat”—can explain some efficiency differences between Windows and Linux. In his view, Windows can waste power by failing to manage clocks and hardware resources as effectively.
• Low-power testing can expose architectural differences that high-wattage desktop testing may obscure. As an example, the hosts discuss an AMD APU with a 64-bit memory interface that performed surprisingly well, suggesting that memory bandwidth and architecture can matter as much as core count.
• The Phawx describes using Steam Deck’s developer tools to capture GPU traces. In principle, an AI could analyze a trace and help identify game-specific Proton or graphics optimizations. This is presented as a potential workflow, not a finished tool or demonstrated tutorial.

Xbox Helix and Steam Access

• The hosts argue that access to Steam could make the rumored Xbox Helix much more attractive. A powerful living-room device that can run PC games from multiple stores would offer a clearer value proposition than one limited to Xbox software.
• They acknowledge Microsoft’s financial concern: Steam sales would not generate the same revenue for Xbox as purchases through Microsoft’s own store. Possible compromises discussed include allowing Steam while promoting partner stores or offering a less-subsidized version of the hardware.
• Their broader point is that an open, PC-like console could attract players who want flexibility, particularly if PlayStation loses goodwill. They also expect users to find ways to run Steam on restricted hardware regardless, potentially with AI-assisted hacking lowering the technical barrier.

PlayStation Strategy and Backward Compatibility

• The Phawx remains interested in the rumored PS6 handheld, especially its price and role as a lower-cost option in a PlayStation hardware lineup.
• He still values PlayStation’s narrative games and technical presentation, but says the PS5 generation has offered relatively few games that personally motivated him to buy the system. He notes that PlayStation’s large, established customer base could still carry the brand through a difficult period.
• Tom argues that Sony should rebuild goodwill by reconsidering disc support, improving communication, and expanding PC releases and remasters. They discuss a broader catalog of older PlayStation games—including PS1, PS2, and PS3 titles—as a potential selling point for a future console.
• Both see AI-assisted reverse engineering and recompilation as a threat to the traditional exclusivity model. They expect unofficial PC versions of some PlayStation games to become increasingly feasible, though the pace and quality remain uncertain.
• They also discuss game preservation: AI tools could help revive games dependent on discontinued servers, adapt VR games to other headsets, or help recreate missing services. These are possibilities, not guaranteed outcomes.

AI’s Effect on Games and the Industry

• The Phawx says recent AI models have become much more capable at larger technical tasks, including interacting with a computer and carrying out instructions. He expects this to reduce the practical skill and effort required for tasks such as porting software or configuring emulators.
• AI-assisted ports could challenge publishers’ release strategies: if unofficial PC versions arrive quickly, publishers may have less time to sell delayed PC ports. The hosts discuss GTA VI as a high-profile example, but do not claim that an unofficial port is imminent or certain.
• They also see potential benefits for development. AI agents could play games at scale, flag bugs, and help QA teams verify problems. The Phawx suggests that human testers could supervise fleets of agents rather than simply being replaced, although job impacts remain an open concern.
• AI could help preserve discontinued online games by reconstructing server behavior, and could assist with bringing old VR or motion-control titles to new hardware.
• The hosts recognize serious unresolved issues around copyright, training data, piracy, and compensation for creators. Their view is that the tools are advancing rapidly, even as the legal and ethical questions remain unsettled.

GTA VI and Mobile Gaming

• The hosts debate whether the possibility of rapid unofficial ports could affect Rockstar’s PC release timing or the performance expectations for the console version. They emphasize that the outcome depends on technical hurdles, including access to a suitable PS5 firmware exploit.
• The Phawx has preordered the Xbox version, partly because he hopes Helix will support PC games. Both note that if an unofficial PC version became available before a paid PC release, it could frustrate buyers and publishers.
• They discuss whether more PC games will be ported to phones as mobile chips improve. The Phawx thinks tools and collaborations could make ports cheaper, but points out that controller support and the lack of convenient gaming-phone hardware remain obstacles.
• Valve’s work on software layers that could run PC games on ARM phones is presented as a possible way to let users play games they already own. The hosts also note that dedicated mobile ports have often struggled to sell well.

DLSS 3.7 on Radeon Hardware

• The hosts discuss a community effort to run DLSS 3.7 on AMD Radeon GPUs, including older cards. In a demonstrated example, they say its image quality and frame-time cost looked better than FSR4 on a Radeon RX 5700 XT.
• They caution that the evidence is limited and that image artifacts, compatibility, and performance across more games still need testing. The implementation also appears less convenient than a native, turnkey feature—especially on handhelds, where interacting with overlays can be awkward.
• If the approach becomes reliable and easy to use, it could weaken Nvidia’s software advantage by making some Nvidia features available on competing hardware. The Phawx also sees AI-assisted translation between software ecosystems as a way barriers such as CUDA dependence could erode over time.

Radeon RDNA 5 and the RTX 5090

• The hosts react to a claim that AMD’s large AT0 design is intended for gaming as well as enterprise use. They speculate that a gaming version could have a very large performance and memory-bandwidth advantage, but stress that performance estimates are not confirmed specifications.
• They also discuss rumors that the RTX 5090 may be nearing end-of-life and that a 24 GB RTX 5080 could take its place. Tom says a contact reported no restock date for the 5090 at one company, but explicitly treats that as one data point rather than confirmation.
• Because of unusually high resale prices, both consider selling older high-end cards such as the RTX 4090 and using a less expensive Radeon card instead. The Phawx says his RX 9070 XT provides satisfactory performance with FSR4 in his use, despite not matching a top-tier Nvidia card in raw performance.

Steam Deck 2 and AMD Handheld Chips

• Tom says he has confirmation that AMD developed an APU called Gainsboro for one customer, possibly Valve, but says he does not know whether Valve will use it in Steam Deck 2.
• A separate, unverified claim says the chip could have six Zen 6 CPU cores and 12 RDNA 4M compute units. The Phawx emphasizes that the exact GPU architecture matters: RDNA 4M could mean a more capable design, or it could be an older graphics base with some newer AI features.
• His rough estimate for a 15-watt handheld is around twice Steam Deck performance, with results varying by game. He argues that faster memory would be important; if bandwidth remains limited, extra GPU compute may not deliver its full potential.
• He notes that running all components at maximum clocks can require far more power than a handheld can sustain, so a realistic assessment must account for the power budget and thermal limits. He also sees hardware-accelerated FSR4 as potentially important to the device’s practical performance.
• The hosts disagree somewhat on whether Valve should use Gainsboro or wait for newer hardware. The Phawx prefers waiting for a stronger future APU, particularly one based on RDNA 5, while Tom suggests that memory availability and product timing may be major considerations.
• They warn that a delayed, expensive handheld could face rapid obsolescence as newer APUs arrive. The Phawx’s own ideal future device is a high-end Medusa Halo-class handheld capable of serving both portable and docked gaming needs.

AMD Z-Series Chips and AM5 APUs

• The Phawx criticizes AMD’s Z-series handheld chips as largely repackaged laptop APUs rather than a consistent range of purpose-built handheld processors. He says a true handheld chip would prioritize a capable GPU and low-power CPU cores rather than simply adapting larger laptop designs.
• A Zen 6 leak discussed on the show suggests AM5 APUs such as Medusa 1 and Bumblebee, with some configurations reportedly using RDNA 4M graphics. The speakers stress that the information is incomplete and that exact specifications and product status are unknown.
• Both agree that desktop APUs can be constrained by memory bandwidth, making a powerful integrated GPU less useful unless the memory system can feed it adequately.
• They criticize AMD for not bringing newer graphics architectures to more APUs sooner, arguing that RDNA 4 could materially improve low-power gaming performance. The Phawx views Intel’s Panther Lake graphics as a serious competitive warning for AMD.

NPUs and AI Acceleration in Games

• The Phawx questions the usefulness of NPUs in consoles and gaming PCs, particularly for image upscaling. He says an NPU operating on a completed frame can add latency because it is outside the game’s normal rendering pipeline.
• He contrasts that with AI operations integrated into GPU compute units, which could access rendering data more directly and potentially avoid some of the latency and coordination costs.
• The hosts question what game developers would use a console NPU for if games must also run on PCs and other consoles without the same hardware. Possible uses such as NPC behavior are raised, but neither speaker sees a clear, compelling use case yet.
• They conclude that NPUs may remain underused in gaming unless developers find a practical workload that benefits from dedicated AI hardware.

Reviews, Guides, and Practical Advice Mentioned

• The Phawx’s channel: Handheld and APU testing focused on performance per watt, clock tuning, and extracting useful performance at low power.
• Steam Deck profiling: The Phawx mentions using the Steam Deck developer client’s GPU tracing tools. AI-assisted trace analysis is discussed as a possible optimization technique, not a completed step-by-step guide.
• Product assessments: The Phawx says the Snapdragon X2’s CPU performance is strong but its GPU is less competitive; he also discusses testing AMD and Intel handheld-class APUs.
• Buying advice: The hosts caution against paying a premium for hardware that may be quickly surpassed, while acknowledging that individual needs and launch timing matter. They also discuss selling unusually valuable older GPUs, but do not offer a universal recommendation.
