Yea the old narrative of "arm is power efficient, but doesn't actually run real desktop level stuff at that power level" is pretty dead at this point.. it now runs desktop level stuff at 3x lower power than intel's latest chips.. and the potential for apple's chips to keep improving at that same power envelope is definitely there.. so...
Dumb question, but whats the engineering principle behind higher performance when increasing power usage? Is it because pipelines are clocked faster?

This article is benchmarking the CPU alone but measuring the wattage of the whole machine, including a dedicated 3080ti which is obviously not relevant to a CPU benchmark. It would make more sense to do this benchmark on a laptop with an integrated GPU.
Knowing intel and PC manufacturers you most likely won't find this CPU in a laptop without a dedicated GPU. I gave up the last time I was looking for a new laptop (I ended up with a MacBook Air), but it was surprisingly hard to find a laptop that had a beefy CPU but no discrete GPU. Lenovo had a couple of think pads that had some offerings but they would make you jump to the intel CPU with vPRO and that would come wi…
A lot of people want gaming laptops, so systems with big GPUs and big CPUs and not so great size/weight/battery life can be had relatively cheap.
But most people that want big CPUs and good battery life but don't care about the GPU so much are people who need the system for their job, so manufacturers can get away with pricing those systems higher.
IMO - it would be interesting to see benchmark of P and U series Laptops. Honestly I do not think they are going to beat Apple M1 yet - but having a 14 or 10 core CPUs in I do not think Intel is even after Apple yet but they look to have caught up and surpassed AMD with this release for sure.
For enthusiast in me - who likes a Laptop that can run Linux without problems, an all Intel 14core Laptop with <45w power budget will be great.
If (eg) Intel are doing something smart in L1 cache, or ensuring no stalls, it would be cool if its applicable to ARM derived hardware. And if not, it would be cool to see how it maxes out, and how a future ARM tick-tock response in time shows benefits in different spaces.
Also, this at LEAST a 2D cost/benefit matrix now. Speed+Power. Sometimes, no point being fastest if it costs more and your battery runs out faster. Remember Apple puts the M1 in portable units, where power/battery is a significant "feature" behind the purchase. Yes, I run my apple mostly plugged in. The time I get off-plug is huge. Faster intel which drains me on a flight isn't a plus.

With RTX 3080 Ti though. So yeah - I don't think it can match Apple M1 efficiency but reviews of P-series and U-series Alder Lake mobile CPUs are going to be interesting and what I am looking forward to.
That's fair, I missed that. In that case it sounds like the comparison itself was flawed by comparing two devices in such different perf envelopes. Nevertheless, it's not a great first showing.
Intel’s lower power chips may be able to match/beat the M1 range’s power draw, but one would assume they can’t keep up that level of performance while doing it.
Apple seems to have the best of both worlds at the moment. It can perform very well or go really low peer with a single chip.
Dumb question, but whats the engineering principle behind higher performance when increasing power usage? Is it because pipelines are clocked faster?

- longer pipelines - more silicon dedicated to speculative execution for more Instruction Level Parallelism - bigger caches - More analysis of incoming instruction stream to get more ILP and out of order execution
But yeah, more clock is more power is more heat.
> During the Cinebench R23 multi-core test, the Alder Lake laptop was consistently in the 100-watt range, [...] M1 Max’s power draw was 39.7 watts Ouch. > MSI GE76 Raider got 6 hours of offline video playback, a far cry from the MacBook Pro’s 17 hours. Double ouch. That's a huge gap, and 6 is low even in absolute terms. It's still a nice beefy chip, but still a far cry from the engineering marvel that Apple pulled of…
The MSI GE76 Raider's 3080TI is nothing Apple can match, so there are factors than other just wattage and battery life.
On the other hand it’s needed. The Intel integrated GPU was 1/2 what the M1 Max did. Apple could theoretically add a discrete GPU too, but they won’t.
They should change the title to "slightly faster at massively larger TDP"
