RPCS3 Team Believes PlayStation 6 Could Finally Be Powerful Enough for Proper PS3 Emulation
The future of PlayStation backward compatibility may depend heavily on the PlayStation 6. According to comments from the RPCS3 development team, Sony’s next-generation console could be the first PlayStation system with enough CPU power to properly emulate PlayStation 3 games.
RPCS3, the well-known PlayStation 3 emulator for PC, recently introduced a major feature that allows users to run physical PS3 games directly from Blu-ray discs, though the feature comes with some limitations. After the announcement, one user questioned whether Sony could have added official PS3 game compatibility on older consoles if it had wanted to.
The RPCS3 team pushed back on that idea, arguing that the PlayStation 4 simply did not have the processing power needed for reliable PS3 emulation. The team described the PS4’s AMD Jaguar CPU as extremely weak for this task, even suggesting that in raw number-crunching performance, it could fall behind the PS3’s unusual Cell processor.
That matters because PlayStation 3 emulation is notoriously demanding. The PS3’s Cell architecture was powerful but complex, making it difficult to reproduce accurately on modern hardware. RPCS3 requires a strong CPU to deliver smooth performance, and the emulator’s recommended high-end setups include modern processors such as AMD Ryzen 9000-series chips and Intel’s latest multi-core CPUs. For the best results, CPUs with exceptional gaming and cache performance are often preferred.
With that in mind, it is easy to see why the PS4 was never a realistic candidate for full PS3 emulation. Its 8-core Jaguar processor was designed for efficiency and cost control, not the intense workload required to emulate the Cell processor accurately. Even the PlayStation 5, which uses a much stronger 8-core Zen 2 CPU, may still fall short of what is needed for consistent, high-quality PS3 emulation across the full library.
The situation could change with the PlayStation 6.
Current rumors suggest that Sony’s next console may use a much more advanced 10-core Zen 6-based CPU. If accurate, that would represent a massive leap over the PlayStation 5’s Zen 2 processor, which is based on older CPU technology. A stronger CPU would give Sony far more room to handle the demanding process of PS3 emulation without major performance compromises.
The RPCS3 team believes the PS6 should be the first PlayStation console truly capable of emulating PS3 games properly. That does not mean Sony will definitely include official PS3 backward compatibility on the PlayStation 6, but it suggests the hardware barrier may finally be low enough for Sony to make it happen if the company chooses to.
For many PlayStation fans, native PS3 support on PS6 would be a major selling point. The PS3 library includes beloved titles that remain difficult to access on modern consoles, especially games that never received remasters or ports. Proper PS3 emulation could help preserve those titles and make the PlayStation 6 feel like a more complete legacy platform.
However, there are still questions. Reports have suggested that the PS6 may not focus heavily on physical media, and it is unclear whether Sony plans to offer a disc-to-digital conversion system. If the console launches without a disc drive or without support for older physical games, PS3 backward compatibility may depend entirely on digital purchases or subscription-based access.
Still, the possibility is exciting. If the rumored PlayStation 6 CPU upgrade is accurate, Sony may finally have the hardware needed to bring proper PS3 emulation to a home console. Whether the company chooses to take advantage of that power remains to be seen, but for players hoping to revisit classic PlayStation 3 games, the PS6 could offer the best chance yet.
