I assume that a core cluster can power off if it's completely idle; this should be more energy-efficient than running both clusters at low utilization.
It can also allow for boosting a core more: the “turbo” ramping is on a per-cluster basis so if only one core is loaded it’ll work at 3.2, two of them at 3.1, and 3 or 4 lowers that to 3.0.

Why are you talking about M1 power draw in your response when that's not the SoC in question? > Also note: in your other comments you keep mixing TDP and wall power draw, Power in == heat out.

Because the thread was about why even an M1 not pro is beating a 16"? You're free to bring in your third option which clobbers it even further , but an $800 fanless machine also clobbers it so it's a perfectly valid comparison when trying to counter weird claims that Apple only just now started working on proper cooling... tl;dr: How can you claim the old 16" is only being beat because Apple just now started to care…
This is completely incorrect. You cannot compare TDPs in any meaningful way except kinda within a single vendor's single generation. There's no standard definition for TDP, so it cannot be generally compared across brands.
And for most brands TDP doesn't have any useful meaning, further eliminating any value to be had from it.
> Wall draw to wall draw, my M1 Air draws under 30W and beats a 16" drawing over 100W
Are you sure? What workload(s)? How did you measure power draw? And 16" isn't a CPU/SoC, so what are you even comparing against? Your M1 Air sure as shit isn't beating the current 100w 16" after all. So I'm guessing you're comparing against a previous MBP 16" of some unknown variety, which one specifically in which configuration?
> TDP to TDP my M1 is 10W to a 16" closer to 100W.
Apple never shipped an Intel CPU with a 100w TDP in any MBP of any size. So not only is this comparison meaningless, you're not even using the right numbers. The i9-9980HK that I'm guessing you're referring to is a 45w TDP. But see above about you can't compare TDPs, they have no meaning.

Apple selling you mid-range-3-year-old-intel CPUs (that are known to thermal throttle quite badly) at 50% markup, then robbing you slightly less hard on a product is not jaw dropping, it's merely you falling for their marketing three times in a row.
Out of curiosity which laptop should I be looking at if I dont want to be robbed by the apple on a M1?
I don't think the GPU is much of an upgrade, but it does have tensor cores, the better video encoder (could be an OBS monster) and I believe better thermals. I am sure putting Pop!_OS or Manjaro on it would make this a great *nix platform for developers, content creators or streamers.

Is that CPU or GPU? Sounds a bit high when 2Gflops/watt (but I guess at 40W for all cores =2,5Gflops/W it could make sense?!) is the industry standard! Can you turn off the acceleration to get CPU only figures? What is FMA/s? Edit: Ok that is some sort of SIMD/GPU... I need figures for the raw CPU that can also do general purpose calculations and branches! Maybe MIPS is a better "apples to apples" measurement?
Ah, it's actually 100gflops (not 100Gfmas) because the fmla instruction is fused. I just ran it on CPU, single core (no pinning), just using the aarch64 fmla instruction. Using pure BLAS (multithreaded, with the MM ISA extension), I get like 1.2TFlops in fp32 on the whole device. Code for the blas test: https://jott.live/code/blas_test.cc
Same as these tests: http://web.eece.maine.edu/~vweaver/group/green_machines.html

I'm having a hard time finding mips/flops for the M1 CPU, can you measure one of them?
Could you give me a benchmark in particular? Or maybe this one works: https://github.com/mmperf/mmperf . I'll run it in an hour.
Just want something that is more "apples to apples" (no pun intended but yes... lol)
Re: M1 Pro First Impressions: Core Management and CPU Performance
#216I can’t wait for the desktop-class Pro hardware. If you extrapolate on power consumption alone it would be a complete monster. They could do something gnarly like fit 8 sockets on a single board and send your compute ability to level 9000. I’m hoping for a mid-tier unit though - a rebirth of the G4 Cube as a “Mac Mini Pro” I daily drive an M1 mini now and abuse the hell out of it. I’ve never heard the fan. It’s a rem…
But performance, even with half the ram, was still stellar. Everything remains speedy, even when it's doing far too much.

The latest Ryzen CPU is the 5950X, costing near 1k, and it’s behind M1 in that same site’s leaderboard: https://www.cpubenchmark.net/singleThread.html All the recent M1 benchmarks from respectable news sites confirm the same for the majority of multi core real workloads. tl;dr you absolutely will not beat M1 Pro with a $1500 PC for work.
Did you miss that I mentioned AMD Ryzen Threadripper 1950X or you're just willingly ignoring it? It beats the M1 and costs > https://www.cpubenchmark.net/singleThread.html > $1000+ territory for the CPU alone to get close to M1 multi-core performance Your claim was that you need a +$1000 CPU to get close to M1 multi-core performance, then now you link the single-thread tests?
Here’s a full comparison between M1 Max and the 1950x: https://browser.geekbench.com/v5/cpu/compare/10837819?baseli...
The M1 Max is ahead by leaps and bounds on many tests despite the synthetic score being close. And these only tell half the story. In all the reviews I’ve seen so far, it consistently beats the iMac Pro by up to 2x-4x in real word tasks. Mind you, the original M1 chip already beat many high-end desktops, so this is not surprising at all.
Even if the cpu was that cheap: $600 cpu + $200 mobo + $100 ram + $100 ssd + $50 power supply + $600 rtx 2060
That’s the best machine you can put together with ~$1500 and it will be absolutely smoked by the M1 Pro/Max. Then you can try to find a mini-led 4k 120hz monitor, peripherals, mic and speakers, all for < $1000 (hint: impossible)… and still not be able to run on batteries or pack it in a bag.

Don't you think it's deserved? I haven't seriously used a macbook in nearly a decade now but the M1 is making me consider buying one. Desktop class performance in a laptop with very long battery life is just amazing. The only thing stopping me is OS X. Using it is super painful for me - it doesn't even have basic snap to edge or split window functionality. My workflow is heavily dependent on tiling WMs and it would a…

> Pick up a Macbook 16 and XPS 15 from 2019 with the same specs (CPU/RAM) and the XPS absolutely runs circles around the macbook when it comes to general responsiveness in UI. All because of cooling. One visit to XPS owner’s subreddit was enough for me to stop entertaining the idea of buying it.
One visit to Louis Rossmann YouTube channel Louis was enough for me to stop entertaining the idea of buying Apple laptops. It's almost like people that have no problems don't go around saying that (except for Apple users)
Re: M1 Pro First Impressions: Core Management and CPU Performance
#220I have an M1 Max. If anyone wants me to benchmark any workflows, I'd be glad to help!
Do you have two 4k displays? If yes, then does running them affects performance significantly? On i9 MBP this was causing extremely severe performance issues, to the point where processor was throttled to 30% performance.
Don't skimp on RAM or buy into the hype that ARM halves the amount of required RAM - it's total BS.
