One of the key reasons the RPCS3 PlayStation 3 emulator for PC remains actively developed is the lack of native PS3 game support on the PlayStation 4 and PlayStation 5 consoles. Whereas RedoEngine has enabled PS3 game play on PS5, the number of compatible titles is currently limited, as it relies on developers implementing support for the emulator within their games.
In recent years, the RPCS3 project has focused on improving performance for x86 processors and expanding support for laptops with processors ARM, with the latest version bringing performance levels nearly on par with x86-based systems.
RPCS3 improves PS3 emulator performance on ARM processors
This allows users with a MacBook or a laptop with a Qualcomm ARM processor to enjoy more than 2,600 officially supported PS3 games on their devices, signaling the project’s continued viability. The latest update for devices with Qualcomm ARM processors and Apple’s M-series chips leverages ARMv8 (SDOT / UDOT) instructions to accelerate the mathematical operations used by the emulator to simulate PS3 hardware.
New CPU emulation optimisations for arm devices!This takes advantage of armv8 SDOT/UDOT instructions to optimise the SUMB SPU instruction – a similar optimisation that we already have in place on x64 using VNNI instruction.
GB/GBH/GBB were also optimised with UDOT. https://t.co/R3wC9tcuz0

What we have is significant because these parts of the SPU are used by games, and optimizing them for ARM processors improves performance, reduces CPU load, and speeds up games that previously ran slower, bringing them closer to the performance levels seen on x86 architecture.
This optimization was previously available through VNNI, an instruction available on Intel and AMD processors. It’s important to note that this update only affects devices with ARM architecture PCs, not mobile devices.
The RPCS3 team previously announced it was ending development for Android to focus resources on PC versions for Windows, macOS, Linux, and FreeBSD for both x86 and ARM. You can download the latest version here.
What other new features will be included in RPCS3?
Users can now add any available game directly to Steam through RPCS3. This allows users to utilize Valve’s platform as a unified game launcher, avoiding the emulator’s long-standing, largely unchanged user interface.
This is one of the changes planned for the application, a user interface update that will be appreciated by users of portable consoles, for whom the reduced screen size makes interacting with RPCS3 more tricky. The developers intend to deliver a complete interface redesign to simplify interaction and library management.
Frequently asked questions about RPCS3 on ARM processors
Which ARM processors are compatible with this RPCS3 update?
The update is optimized for Qualcomm ARM processors (Snapdragon series for PC) and Apple chips (M series: M1, M2, M3, etc.). It’s important to note that this version is exclusive to ARM architecture PCs, not mobile devices like smartphones or tablets.
How many PS3 games can I play with RPCS3?
Currently, more than 2,600 PlayStation 3 games are officially supported by the RPCS3 emulator. The new optimization for ARM processors allows you to enjoy this catalog with performance similar to that offered by PCs with Intel and AMD processors.
Can I use this version of RPCS3 on my Android mobile?
No. The RPCS3 development team announced that it was abandoning development for Android to focus all its resources on PC versions (Windows, macOS, Linux and FreeBSD). This optimization for ARM is aimed exclusively at laptops and desktop computers with ARM processors.
What specific improvements does this update bring for ARM?
The update leverages ARMv8 (SDOT/UDOT) instructions to accelerate the mathematical operations the emulator uses to simulate PS3 hardware. This improves overall performance, reduces CPU load, and speeds up games that previously ran slower on ARM architecture.
