Incredible the perf they get out of it. Bit confused with the graph towards the end, is perf better under Rosetta than natively?!

The rosetta vs native vs 9900k vs 8559h graph? The only game rosetta is beating native on is rogue squadron 2. Since Dolphin is a JIT, this seems to be a case of where Rosetta's JIT is smarter than Dolphin's in terms of which ARM instructions are chosen when converting from the Intel instructions than Dolphin when converting from the emulated PPC instructions. Unless you're comparison is the 8559h and not the "native…

According to the article, the AArch64 JIT isn’t as complete as the x86 one so some less common instructions are emulated, not JITed. I imagine a game that uses a lot of these is slower with the native ARM version.

Wow, that frames per watt graph is an eye opener for sure. What an incredible advancement in mobile computing.

Ftr, this is Dolphin the games emulator, not Dolphin the KDE file manager.

I truly came here thinking about Dolphin the mobile browser.

It's a petty thing, but that chart annoys me to no end. The numerator is FPS, not frames, so frames / watt should've been labeled frames / joule (or, well, FPS / watt, but that's nowhere near as fun).

Nor Flipper -- the cult TV show that featured a crime fighting dolphin (I kid you not).

The real challenge is running F-Zero GX. I’d love to see some benchmarks for this game — the hardest game to emulate.

In the case for Apple Silicon, the next generation will be even better and is not far off from announcing the newer processors that will supersede M1 in WWDC. The M1 only shows what's possible for Apple Silicon and the newer generation of ARM-based Macs will impre…

In 5 years there will be 1nm transistors. If you skip this generation, you might as well wait another year to get high end stuff and you won't have to deal with Apple's less than friendly practices.
