RG477M vs RG557 vs Odin 2: PS2 & Switch Emulation Performance Comparison
Anbernic RG477M
Anbernic RG477M (bronze model) – a 4.7-inch Android handheld with a metal shell. The RG477M is Anbernic’s latest premium metal handheld (launched August 2025) built for high-end emulation. It features a 4.7-inch LTPS touchscreen (1280×960 resolution, 4:3 aspect, 120 Hz)retrohandhelds.gg. Under the hood it uses the MediaTek Dimensity 8300 processor (octa-core 4 nm SoC) with a Mali-G615 MC6 GPUretrohandhelds.gg. This chipset is offered with 8 GB or 12 GB of LPDDR5X RAM and 128 GB or 256 GB of internal storageretrohandhelds.gg, running Android 14 out of the boxretrohandhelds.gg. In terms of raw power, the Dimensity 8300 is a huge leap over Anbernic’s previous T820-based devices – roughly 50–80% faster by Geekbench scoresretrohandhelds.gg. Essentially, the RG477M shares the same high-end internals as the larger RG557notebookcheck.net, but in a more pocket-friendly form factor (4.7″ screen and ~354 g metal body).
PS2 Emulation: Thanks to its powerful SoC, the RG477M can handle PlayStation 2 emulation quite well. In fact, the Dimensity 8300 has enough CPU/GPU muscle to run most PS2 titles at full speed on the 4.7″ 960p display. User tests on the identical RG557 (same chip) show many games reaching full framerates: for example, Need for Speed: Most Wanted ran at a stable 60 FPS on 2× resolutionretrohandhelds.gg. That said, some heavier PS2 titles still push the device – Gran Turismo 4 saw sub-20 FPS slowdowns at 2× resolutionretrohandhelds.gg, and Jak II exhibited missing textures and dips into the 40s FPSretrohandhelds.gg. These issues suggest that while the raw performance is ample, emulator optimization and drivers matter. Notably, early firmware on the RG557/RG477M seemed to throttle performance; one review found the RG557 “should be performing way better” – even a Snapdragon 865 device was outperforming it until software updates fix the throttlingretrohandhelds.gg. With proper configuration (using AetherSX2 emulator) and potential firmware patches, the RG477M should comfortably play the majority of PS2 classics at native or enhanced resolution. Active cooling (fan + heatpipe) in the device further helps sustain high performance during long PS2 sessionsretrohandhelds.gg.
Switch Emulation: Running Nintendo Switch games on the RG477M is possible but more limited. The device’s Mali GPU and Mediatek drivers are less optimized for Switch emulators compared to Qualcomm’s GPUs. Community feedback notes that “all the high-end emulators (GC/PS2 and newer) have well-documented issues on Mediatek chips”, including games failing to run or crashing due to lack of proper GPU driver supportreddit.com. In practice, some lighter Switch titles can run on the Dimensity 8300 – for instance, one user reported Fire Emblem Engage ran pretty well on a Mali-based handheldreddit.com. In a surprising case, the Dimensity 8300 was even shown booting Zelda: Tears of the Kingdom (which a Snapdragon 865 couldn’t)reddit.com, hinting at the chip’s raw capability. However, expectations should be tempered: many Switch games may suffer from graphical glitches, instability, or low performance on RG477M. Unlike PS2/GC emulation (which the RG477M handles largely through brute force), Switch emulation is “hit or miss” on Android – even more so on Mali GPUs. There are no custom drivers like the Turnip (Adreno) drivers for Mali, so compatibility is the main bottleneckreddit.com. In short, the RG477M can emulate some Switch games as a novelty, but it’s not a reliable Switch game machine. Users wouldn’t buy this specifically for Switch – there’s “no guarantee the games you wanna play will work”, as one Odin 2 owner similarly noted about Android Switch emulationreddit.com.
Anbernic RG557
Anbernic RG557 in White and Transparent Purple – a 5.5-inch AMOLED Android handheld (Dimensity 8300-powered). The RG557 is a larger sibling to the 477M, sharing the same Dimensity 8300 SoC and Mali-G615 GPU, but with a bigger 5.48-inch 1080p AMOLED display (1920×1080, 16:9)retrohandhelds.gg. It comes with 12 GB RAM and 256 GB UFS 4.0 storage standardretrohandhelds.gg. The RG557 runs Android 14 and was Anbernic’s most powerful handheld upon its mid-2025 releaseretrohandhelds.gg. It adds some ergonomic refinements – Hall-effect analog sticks and Hall-effect analog triggers for precise control, a more “bubbly” hand-friendly shape, and active cooling to sustain performanceretrohandhelds.ggretrohandhelds.gg. In essence, the RG557 and RG477M are nearly identical in performance capabilities; the main differences are the screen (5.5″ 1080p vs 4.7″ 960p) and form factor. The larger 1080p display offers sharper visuals, though it also means the GPU has to drive ~60% more pixels than on the 477M – a consideration for high-resolution emulation.
PS2 Emulation: The RG557’s power is sufficient to emulate PlayStation 2 and comparable “6th-gen” consoles (GameCube, etc.) quite impressively. Anbernic advertises the RG557 as capable of PS2, PSP, GameCube, and even select Wii U titlesgeeky-gadgets.com, making it their first device to comfortably tackle that generation. Real-world tests confirm strong performance but also revealed some software issues at launch. Lighter and well-optimized PS2 games run smoothly – e.g. Need for Speed: Most Wanted hit a solid 60 FPS at 2× upscale on RG557retrohandhelds.gg. On the other hand, very demanding games or poor Mediatek GPU drivers caused problems: as mentioned, Gran Turismo 4 on PCSX2 struggled on RG557 (sub-20 FPS) and Jak II showed missing graphics and frame dropsretrohandhelds.ggretrohandhelds.gg. These issues suggest the RG557’s hardware should handle those games, but the current emulator or firmware wasn’t fully optimized – indeed, reviewers suspect the Android build was throttling performance or not utilizing the chip fullyretrohandhelds.gg. A subsequent firmware update (v1.24) was released to improve performance and even enable dual-screen mode for DS/3DSanbernic.comanbernic.com, indicating Anbernic’s active effort to fix early issues. With updates and using the optimal emulator settings (e.g. AetherSX2’s “Fast” preset, 1× or 2× resolution for heavy games), the RG557 can deliver excellent PS2 gameplay. It easily outclasses older Snapdragon 845/865-based handhelds in raw benchmarks – the Dimensity 8300 has ~25% higher single-core and ~31% higher multi-core than a Snapdragon 865 (Retroid Pocket 5)retrohandhelds.gg – so once software catches up, it should “easily beat the RP5 in many PS2 games”reddit.com on sheer power. Battery life is also decent during emulation thanks to the efficient 4 nm chip (5,500 mAh battery for ~7–8 hours gaming)retrohandhelds.gg.
Switch Emulation: When it comes to Nintendo Switch emulation, the RG557 faces the same challenges as the RG477M – only magnified slightly by the higher resolution screen and early firmware limits. On paper, the Dimensity 8300’s CPU is powerful enough for Switch emulators, but the Mali GPU drivers lack the custom optimizations that Snapdragon’s Adreno GPUs enjoy. This means many Switch games either won’t run or will have glitches. As one community member put it, the RG557 will “likely struggle with Switch emulation not for lack of raw power, but for lack of proper driver support”reddit.com. In practice, some less demanding Switch titles are playable. For example, users have reported that games like Super Smash Bros. Ultimate, Kirby, and indie titles run well on Android (Yuzu emulator) with Snapdragon 8 Gen2 devicesreddit.com – the RG557’s hardware is somewhat weaker, but in the same ballpark as a Snapdragon 865/870, so it could handle older or 2D Switch games. However, more demanding 3D titles will be hit-or-miss. It’s telling that on the Snapdragon-based Odin, one owner rated Android Switch emulation “7/10” – acknowledging that some games run perfectly, but others have “bearable slowdowns” or “major graphical issues,” and frequent crashes are possiblereddit.com. On the RG557 (Mali GPU), those emulator issues are even more pronounced. You may get certain games running – one comment noted Tears of the Kingdom did boot on the RG557’s chipreddit.com – but overall compatibility is lower than on Odin 2. Without Adreno’s custom Turnip drivers, Mali GPUs can’t easily fix rendering bugs or boost performance in Yuzu. Thus, Switch emulation on RG557 is more of a technical curiosity. It’s capable of running some Switch games in a pinch, but you should expect low success rates and sub-native performance in many cases. In summary, the RG557 is best viewed as a powerhouse for retro (up to PS2/Wii era) and Android gaming – not a reliable Switch emulator device.
AYN Odin 2
AYN Odin 2 (Base/Pro model in white) – a 6-inch Android handheld featuring the Snapdragon 8 Gen 2. The Odin 2 is a flagship-class Android handheld from AYN, and it decisively outguns both Anbernic devices in power and compatibility. Every Odin 2 model is built around the Qualcomm Snapdragon 8 Gen 2 SoC (a 64-bit octa-core Kryo CPU plus Adreno 740 GPU)techradar.com – essentially the same top-tier chip found in phones like the Galaxy S23. It comes with 8 GB (Base), 12 GB (Pro), or 16 GB (Max) of LPDDR5X RAM and fast UFS 4.0 storage (128 GB up to 512 GB)techradar.comtechradar.com. The standard Odin 2 has a 6-inch IPS touchscreen at 1920×1080, while the higher-end Odin 2 “Portal” variant ups that to a 7-inch 1080p OLED at 120 Hzretrohandhelds.gg. All models feature hall-effect analog sticks, analog triggers, dual stereo speakers, Wi-Fi 7, Bluetooth 5.3, and an 8000 mAh battery with 27–65 W fast chargingretrohandhelds.ggretrohandhelds.gg. In short, the Odin 2 is an absolute powerhouse for a portable – effectively “an Android phone wrapped in a gaming controller,” as TechRadar quipstechradar.com. It is widely considered “the new king of Android handhelds”, given that it was designed to push the boundaries of emulation.
PS2 Emulation: The Odin 2’s Snapdragon 8 Gen2 makes PlayStation 2 emulation trivial. In fact, it can not only run PS2 games at full speed, but often at enhanced resolutions and frame rates. TechRadar notes that with Odin 2, you can play anything “up through and beyond” the PS2/GameCube era, even upscale those games to 4K on an external display if desired – and it’s “almost flawless,” far better than what the original Odin could dotechradar.com. In testing, even the most demanding PS2 titles can be handled. For example, RetroResolve reported that The Simpsons: Hit & Run (a known heavy PS2 game) runs on Odin 2 in 1080p at a solid 60 FPS without needing to enable high-performance mode – the device’s fan stayed nearly silent, underscoring how advanced the hardware isretroresolve.comretroresolve.com. This means God of War, GTA San Andreas, Gran Turismo 4, and other iconic PS2 games can all be played at full speed, often with 2×–3× resolution scaling, on the Odin 2. The Adreno 740 GPU has excellent driver support (including the open-source Turnip drivers), so graphical glitches are rare compared to Mali-based devices. Essentially, Odin 2 can brute-force PS2 emulation and even improve it: players can enjoy higher resolutions, texture filtering, and consistent 60 FPS in games that originally struggled on real PS2 hardware. The experience is so good that one reviewer stated “if it runs on Android, it runs on the Odin 2” – you can throw any console up to 6th-gen at it and expect full-speed resultstechradar.com. Battery life holds up decently under PS2 load as well; the 8000 mAh pack gives around 6–7 hours of intensive 3D emulation, or much longer for lighter retro gamestechradar.com.
Switch Emulation: This is where the Odin 2 truly distances itself from the Anbernics. Thanks to the Adreno GPU and Snapdragon’s driver advantage, the Odin 2 can run a surprisingly large portion of Nintendo Switch titles at playable performance. Early on, many doubted an Android handheld could emulate Switch (even Valve’s x86 Steam Deck struggles with some Switch games)retroresolve.com. But the Odin 2 defied expectations – testers were “surprised by how well Switch games run” on itretroresolve.com. Lighter titles like Cuphead, New Super Mario Bros. U Deluxe, or Super Mario Bros. Wonder run flawlessly on Odin 2retroresolve.com. More impressively, the Odin 2 can tackle big 3D games: The Legend of Zelda: Breath of the Wild runs at roughly its native Switch performance (~30 FPS with occasional dips) on Odin 2retroresolve.com. Zelda: Tears of the Kingdom, an even more demanding title, is playable as well – slightly less stable than BotW, but the fact it runs at all on Android is astonishingretroresolve.com. Likewise, Super Mario Odyssey and Pokémon Legends: Arceus, which often break on weaker devices, ran completely playable on the Odin 2 after installing the latest Turnip GPU drivers (which fixed remaining artifact and texture issues)retroresolve.com. In one 13-game test suite of Switch titles, 12 out of 13 games ran well on Odin 2 – the only failure was a game not yet compatible with Yuzu’s Android build (an emulator limitation, not a hardware fault)retroresolve.com. These results speak volumes: the Odin 2 is currently the best Android handheld for Switch emulation. It benefits greatly from the active development of Yuzu and Skyline emulators and the community-shared Adreno driver improvementsretroresolve.comretroresolve.com. That said, Switch emulation on Odin 2 isn’t perfect or turnkey. Some games still require tweaks (custom mods, 30→60 FPS patches, etc., which not every user will manage)retroresolve.com, and occasional crashes or non-working games exist because the emulator is “bleeding-edge” techretroresolve.comretroresolve.com. Even so, Odin 2 owners report high satisfaction – what was “almost brand new” technology became a bonus feature that significantly extends the device’s libraryreddit.com. You wouldn’t buy a weaker handheld for Switch emulation, but with Odin 2 you practically get a portable Switch in addition to a top-tier retro emulator. As one reviewer summarized: the Odin 2 puts “almost any game you can think of at your disposal,” from retro classics up to modern titles, all in one devicetechradar.com.
Conclusion: Most Powerful Device for PS2 & Switch Emulation
In this comparison, the AYN Odin 2 clearly stands out as the most powerful and capable handheld for PS2 and Switch emulation. With its Snapdragon 8 Gen2 chipset and Adreno GPU, the Odin 2 not only outperforms the Anbernic RG477M and RG557 in raw speed, but also enjoys far better emulator compatibility (thanks to superior drivers). It can run essentially the entire PS2 library at full speed – often with enhanced resolution – whereas the Dimensity 8300-based RG477M/RG557 sometimes struggle with the heaviest PS2 titles or encounter graphics bugs due to Mali driver limitationsretrohandhelds.ggretrohandhelds.gg. When emulating Nintendo Switch, the gap widens further: Odin 2 is able to play a wide range of Switch games at decent frame rates (including large 3D games like Zelda and Mario)retroresolve.comretroresolve.com, while the RG477M/RG557 can only handle a few lighter Switch games, and even those with more frequent issuesreddit.comreddit.com. In practical terms, if your priority is PlayStation 2 emulation, all three devices can get the job done for most games, but the Odin 2 offers more headroom – you can apply higher upscale factors and expect smoother performance on demanding titles. The RG557/RG477M are still very capable for PS2 (they are among the first Anbernic devices to reach this level), but may require more tweaking and are reliant on Anbernic’s firmware optimizations to reach their full potentialretrohandhelds.gg. For Switch emulation, the Odin 2 is in a different class entirely; it is the only one of the trio that one might reasonably use as a portable Switch substitute, albeit understanding the emulator’s growing pains.
Between the RG477M and RG557, the performance is essentially the same – both use the Dimensity 8300 – so neither has a significant power advantage. The choice there comes down to form factor: the RG557’s 5.5″ 1080p AMOLED screen offers a sharper, widescreen image (better for 16:9 content and Android games), whereas the RG477M’s 4.7″ 960p display is 4:3, which many retro gamers prefer for classic consoles. The RG477M’s slightly lower resolution can actually be beneficial for emulation (since a 2× PS2 or 3× GameCube upscale fits its 960p screen nicely with less GPU load), meaning it may hit full speed in a few scenarios where the RG557 (at higher res) has to drop settings. On the other hand, the RG557’s larger battery (5,500 mAh vs ~5,300 mAh) and bigger chassis could allow a bit more sustained performance if heat is a concern, and its AMOLED panel delivers richer colors. In any case, neither Anbernic device can catch the Odin 2 in pure performance or Switch-playability. The Odin 2 not only has more powerful hardware, but also the advantage of Qualcomm’s ecosystem – something explicitly wished for by Anbernic enthusiasts who lament the Mali driver issuesreddit.comreddit.com.
Verdict: For PS2 emulation, all three handhelds are competent, but the Odin 2 provides a smoother, upscale-enhanced experience with minimal troubleshooting. For Switch emulation, the Odin 2 is by far the most viable choice – it is “powerful and compatible” enough to run many Switch titles, whereas the RG477M and RG557 are limited to a few successes and otherwise strugglereddit.comretroresolve.com. If you want the absolute most powerful retro handheld that can handle everything from NES up through PS2, GameCube, Wii and even a good chunk of Switch, the Odin 2 is the clear winner. The Anbernic RG557 and RG477M are excellent mid-high tier emulation devices (and arguably the best Anbernics to date for power), perfectly fine for PS2 and below – but they fall short of the Odin 2’s “do-it-all” prowess. In summary, Odin 2 is the most capable overall, especially for the demanding task of Switch emulation, while the RG557/RG477M offer strong performance for their price range but can’t quite reach the same heights in the most challenging systems.
