How the ARM Architecture of Apple Silicon Affects GameCube Emulation on Switch

The introduction of Apple's M1 chip has brought about significant improvements in energy efficiency and performance in various applications. One such area where this has had a notable impact is game emulation, particularly with regards to the Nintendo GameCube and Wii consoles. The Dolphin emulator, which is a popular choice for emulating these consoles on PC and Mac, has been working on optimizing its support for M1 Macs.

As developers have shown, the ARM architecture of Apple Silicon offers impressive energy efficiency when it comes to rendering frames. In comparison to Intel-based MacBook Pros, the M1 chip can render 8.94 frames per watt, while Intel-based devices only manage 1.38 frames per watt. This significant difference in performance is likely due to the more efficient design of the ARM architecture.

However, the results are not limited to just energy efficiency. In practice tests, the Dolphin emulator has been shown to perform significantly better on M1 Macs than on Intel-based machines. For example, Super Smash Bros., a popular GameCube game, runs at 120 fps on the native version of Dolphin on an M1 Mac, compared to only 71 fps on an Intel MacBook Pro.

The performance difference becomes even more pronounced in other games, such as Star Wars Rogue Squadron II. On an Intel MacBook Pro, this game runs at a mere 16 fps, while on an M1 Mac with Rosetta 2, it runs at 49 fps. This demonstrates the significant impact that the ARM architecture can have on performance.

Despite these impressive results, there is still work to be done before Dolphin emulator can run natively on M1 Macs. As a JIT-compiled emulator, recompiling it for the 64-bit ARM architecture of Apple Silicon was a more complicated task than initially expected. However, early tests suggest that most games ran well and performed better than on an older Intel-based MacBook Pro with a Core i7 processor.

In conclusion, the ARM architecture of Apple Silicon has shown significant promise in terms of energy efficiency and performance when it comes to game emulation. While there are still some challenges to be overcome before Dolphin emulator can run natively on M1 Macs, early tests suggest that it will perform twice as fast on these devices compared to some Intel-based machines. This is an exciting development for fans of retro gaming, and one that demonstrates the potential of Apple's new architecture in this area.
