Do you think the first benchmarks are correct?

In multi-core, its basically on par with an 8-core Intel CPU running at 60 watts. Single-core wise, it’s one of the fastest CPUs that money can currently buy. And it’s a 15W laptop with a single fan. Running without being connected to a charger.
So... pretty much "meh" and nothing special, right?

I don't have much faith he is going to plug it in and re-run the test. Probably have to wait for someone else to remove his crown of thorns.

from the computerbase.de list of r23 results it seems the ryzen mobile chips are quite above m1 in multicore scores( those that actually matter in 3d rendering when doing actual work) , both in under 15watt and 25watt limits .
4800u @25w 10.235 , 10.111
4800u @15w 9674

M1 single core is great . Multi fails sort in this rendering test it seems compared to amd . People who render their work using cinema4d on their laptop should take notice . The rest , not so much .

I am bit skeptical about those 4800U scores. They seem anomalously high compared to third-party reviews. I mean, it’s practically identical to a 45W 4800H above. If I understand correctly, these are user-submitted scores, right? Could be from overclocked systems or not entirely truthful.

Geekbench isn’t the be all end all of benchmarks, its good for bursty workloads and has shown itself to be very inconsistent. This is an Apple forum, and I know a lot of you guys probably aren’t familiar with Samsung’s Exynos processors, but in the Android world they absolutely dominated Geekbench for years, but in real world use, got absolutely stomped by year old Snapdragons which had much lower Geekbench scores.

As for these benchmarks (so far), they are competitive with Renoir, but they don’t dominate AMD’s offerings. Of course they are doing this a lower power draw (I assume). But this is to be expected, they are using a brand new 5nm process, where as AMD is using a 2 year/generation old process node, combined a generation old core. Zen 3 clocks higher, has much higher IPC than Zen 2 did. M1 is very powerful, but it does not seem to dominate X86 as some seem to believe. Apple has excellent engineers, but so does AMD. I am not mentioning Intel because their issues with their process node prevents them from being able to compete with Apple and AMD.

Don’t get me wrong, I love what Apple is doing with their CPUs. I held off getting a laptop, just to wait for this new silicon, but I think some of us should temper of expectations. I can’t wait to get my MacBook Air to compare with my Intel/AMD systems. I suspect those huge caches, along with Safari with be some of the fastest web machines you can buy since Javascript loves cache.

He says Cinebench re-run is not good after plugged in!! :O

If I have depleted my battery for the 16" to less than 50% and then I plug it in, try to run Cinebench, I'll also get "meh" scores because... tada, it's thermal throttling!

He may be seeing proof of thermal throttling. Which is not surprising. First boot = cold MacBook. After running for a while + plugged in and charging = toasty MacBook.

Would be curious if his is Pro or Air. If it's Air, that's expected. If it's Pro, that means thermal throttling may be even worse with Air.

Possibly. Though it could also be the Mac is indexing stuff. I'm hesitant to say thermal throttling is the culprit because of how "power efficient" it is supposed to be.

I think we won't know for sure until more testers (or pro reviewers) do some more benchmarks. In any case, it does sound like the Pro is thermal limited.

No, power throttling should be expected here. This is running a much more powerful chip than the 5W chip in the iPad Air (A14). And heck, the A14 also has thermal throttling.

I've said this before in another thread, but... I think people have unrealistic expectations that somehow, Apple can cram all of this performance into a single chip and still keep the chip operating at maximum efficiency with no throttling at all even without a fan.

Beyond that, Apple stuffed both the Mac Mini and the MacBook Pro with a fan each. I don't think that's a coincidence. The fan is likely very necessary to maintain the high level of performance. I'd fully expect the MacBook Air to not be able to keep up in hot weather or with sustained high load.
