as long as you do your research on the software you use daily. for now there are only a handful of software natively supported.
Non-native apps are, by and large, blindingly fast. Rosetta 2 isn't "emulating Intel instructions in real time" the way Rosetta 1 did for PowerPC. It's
translating the code at either install or first run, so that the code it sees the app will run will, for all future runs, use actual ARM code when possible.
As an example, I used the latest beta of Handbrake to transcode a 4K/60fps ProRes file to HVEC using the software x265 transcoder. (So neither machine would use the T2 or M1 chip's built-in HVEC encoder.)
My 2019 16" MacBook Pro with 45W 8-core Core i9-9880H CPU completed the transcode at the speed of 11.1 fps.
My M1 Mac Mini,
running Intel code through Rosetta 2, did it at a speed of 8.9 fps. In a CPU that is supposedly only 20W.
(There's something wrong with the x265 encoder running ARM-native code, it produces a file FAR larger from the same settings, taking 3 times as long as running in Rosetta mode, so I can't compare to ARM-native.)
Oh, and using the "VideoToolbox" encoder, which uses the hardware HVEC encoders on both, goes at about 45 fps on both. Although it produces a file about twice as large, so it's not quite as efficient. (It gets the same because the HVEC encoder in the M1 is probably the same as in the Intel system's T2 chip.)
