You say something like that about a low power fanless design and every tech nerd's first reaction is "bullshit". And now they want to call you on your bullshit.

"And in MacBook Air, M1 is faster than the chips in 98 percent of PC laptops sold in the past year.1"
There is a subtle difference between "98 percent of laptops sold" and your rephrasing as "2% of laptops you can buy today".
If you doubt the meaning, check out the footnote which refers to "publicly available sales data". You only need sales data if sales volume is a factor in the calculation.
I also don't doubt that "every tech nerd's reaction is 'bullshit'", but only because supremely confident proclamations of universal truth that are soon proven wrong is pretty much the defining trait among that community (c. f. various proclamations that solar power is useless, CSI-style super-resolution image enhancement is "impossible" because "the information was lost", "512k should be enough...", "less space than a Nomad..", and everything Paul Graham has said, ever).
Here, these nerds should have been pointed at, for example, last year's iPad Pro. Which has no fans (only -boys) and was already at that performance level (https://www.tomsguide.com/us/new-ipad-pro-benchmarks,news-28...).
After the odd graphs/numbers from the event, I was worried it was going to be an awful ~2 year period of jumping to conclusions based on:
- Geekbench scores
- "It's slow because Rosetta"
- HW comparisons that compare against ancient hardware because "[the more powerful PC equivalent] uses _too_ much power" implying that "[M1] against 4 year old HW is just the right amount of power", erasing the tradeoff between powerfulness and power consumption
The people claiming this blows Intel/AMD out of the water need to have stronger evidence than comparing against parts launched years ago for budget consumers, then waving away any other alternative based on power consumption.[1]
Trading off power for power consumption is an inherent property of chip design, refusing to consider other chipsets because they have a different set of tradeoffs mean you're talking about power consumption alone, not the chip design.
[1] n.b. this is irrational because the 4 year old part is likely to use more power than the current part. So, why is it more valid to compare against the 4 year old part? Following this logic, we need to find a low power GPU, not throw out the current part and bring in a 4 year old budget part.
IMHO it's much more likely UI people will remember it kinda sucks to have 20 hour battery life with a bunch of touch apps than that we'll clear up the gish-gallop of Apple's charts and publications rushing to provide an intellectual basis for them, without having _any_ access to the chip under discussion, so they substitute iPhone/iPad chips that can completely trade off thermal concerns for long enough for a subset of benchmarks to run, making it look like the the powerfulness/power consumption tradeoff doesn't exist, though its was formerly "basic" to me.
Notwithstanding the fact that you do have a point here, polemically phrased as it may somewhat ironically be, I just want to point out that the Paul Graham reference is probably not the best example of the "tech nerd community" trait you're describing. At least this particular community doesn't quite believe that everything Paul Graham say is true; a couple of examples:
* "Let the Other 95% of Great Programmers In": https://news.ycombinator.com/item?id=8799572
* "The Refragmentation": https://news.ycombinator.com/item?id=10826836
I could share a lot more HN discussions, and some of his essays where he pretty much describe the trait you're taking issue with here -- but I'm already dangerously close to inadvertently becoming an example of a tech nerd that believe "everything Paul Graham has said, ever", is absolutely true ;) I don't, and I know for a fact that he doesn't think so either (there's an essay about that too).
By introducing a new source of information (the memory of the NN) it can reconstruct things it has seen before, and generalise this to new data.
In some cases this means hallucinations, true. But in other times (eg text where the NN has seen the font) it is reconstructing what that font is from memory.
So if we are reconstructing letters from a known font we essentially are extracting 8 bits of information from the image. I'm pretty certain that if you distort the image to an SNR equivalent of below 8 bits you will not be able to extract the information.
Tiny camera shakes on a static scene gives away more information about that scene, it's effectively multisampling of the static scene. (If I have to hunch it, any regular video can "easily" be upscaled 50% without resorting to interpolation or hallucination.)
Our wetware image processing does the same - look at a movie shot at the regular 24fps where people walk around. Their faces look normal. But pause any given frame, and it's likely a blur. (But our wetware image processing likely does hallucination too, so it's maybe not a fair comparison.)
"Faster than 98% of PC laptops"

Your quote is just not very specific. On its face, it could mean every PC Laptop ever produced. I'm somewhat certain that every Apple computing device ever has beaten that standard. Even Airpods and the Macbook chargers might be getting close these days.
I simply can't agree with these logical gymnastics.
Then you have to add on top of that the consideration of what are the laptops people are actually buying and using. I can assure you that neither enterprise clients nor everyone outside of select, relatively spoiled, group people concentrated in just a few areas are regularly buying top of the line workstation or gaming laptops.
The parent is very much right, amongst techies there's an unhealthy tendency for self-righteous adjudication of the narrative or context.
If it ever started to be used in court, Ryan Gosling will have a lot of explaining to do. I hope that day never comes.
Exactly. It's a meaningless number.
They also conspicuously avoid posting any GHz information of any kind. My assumption is that it's a fine laptop, but a bullshit performance claim.
Is that information actually of any real use when dealing with a machine with asymmetric cores plus various other bits on the chip dedicated to specific tasks [1]?
Benchmarks are as good as it gets. Aggregate benchmarks used for marketing slides are less than ideal, but the problem with marketing is that it has to apply to everyone. Better workload focused benchmarks might come out later... In their defense most people won't look at these, because most people don't really stress their CPUs anyway.
Understanding the clock difference between the low energy and performance cores might be an interesting comparator, for example.
I find that Teams, Slack and VS Code running together stresses my 2019 Macbook Pro 16.
Comparing CPUs by GHz is like comparing cars by seeing which car can rev the hardest.
For example when you look up the 15w i5-1035G1 and see 1ghz base, 3.6ghz boost, you can figure out that no, those geekbench results are not representative of the chip running at 15w. It's pulling way, way more because it's in the turbo window, and the gap between base & turbo is huuuuuge.
So right now when Apple claims the M1 is 10w, we really have no context for that. Is it actually capped at 10w? Or is it 10w sustained like Intel's TDP measurements? How much faster is the M1 over the A14? How different is the M1's performance in the fanless Air vs. the fan MBP 13"?
Frequency would give insights into most all of that. It's not useless.
Therefore M1 succeeds to have a slightly higher single-thread performance (between 3% and 8%) than Intel Tiger Lake and AMD Zen 3 at only 2/3 of their clock frequency.
The speed advantage of M1 in single-thread is not high enough to be noticeable in practice, but what counts is that reaching the same performance at high IPC and low frequency instead of low IPC and high frequency results in having the same performance as the competitors at a much lower power consumption.
This is the real achievement of Apple and not the ridiculous claims about M1 being 3 times faster than obsolete and slow older products.
The cores and frequency can scale up and down quickly so there's not a meaningful clock speed measure. The best number you'll get is the maximum frequency and that's still not useful for comparing ARM chips to x86.
Even Intel's chips don't have frequency measures that are all that useful. Some workloads support TurboBoost but only within a certain thermal envelope. Even the max conventional clock for a chip is variable depending on thermals.
I don't think it's worthwhile faulting Apple for not harping on the M series clock speeds since they're a vector instead of a scalar value.
In this case, they make impressive sounding, but almost completely meaningless assertions about performance. If anything, they are underselling an impressive achievement.
Intel does provide performance ranges in thermally constrained packages that are meaningful.
And that's when both the chips are on the same x86 platform. Differences in architecture can never be compared or should be compared with GHz as any kind of basis.
The only place where the GHz is useful for comparison is with products running the same chip

As a Joe Schmoe it's hard to get good figures, but it appears the total laptop market is about $161.952B[1] with the "gaming" laptop segment selling about $10.96B[2]. Since gaming laptops are more expensive this undercounts cheap laptops, but there are other classes of laptop that are going to outperform this mac, like business workstations.
There might be one way to massage the numbers to pull out that statistic somehow, but it is at best misleading.

I'd really suggest you look at the CPU benchmarks (single and multi core) for M1 vs Intel / AMD laptops.
So this statement is made on the basis of what data?
That's the most meaningful constraint for mobile CPUs today, after all.
Apples measurement comes pretty close to comparing "laptops that most people would actually buy". Not sure why it's meaningful that a laptop maker can put out a model that's as thick as a college book, has the very top bins of all parts, sounds like a jet engine when running at max speed, and is purchased by 1% of the most avid gamers.
Oh, and if someone puts out a second model that adds RGB backlit keyboard, but is otherwise equivalent, that should somehow count against Apples achievements, because for some reason counting by number of models is meaningful regardless of how many copies that model sold o_O
If it was Model they would be spinning it. But they said sold in the past year. I dont know how anyone else would interpret it, but in financial and analytics that is very clearly implying unit sold.
Your [1] is Laptop with Tablet, total Laptop market is about $100B, although this year we might see a sharp increase cause of pandemic.
Let say there are $10 Gaming Laptop market. So 10% of Market Value are going to Gaming Laptop. Total Laptop Market includes Chromebook, so if you do ASP averaging I would expect at least 3x ( if not 4x or higher ) difference in Gaming and Rest of Laptop Market. So your hypothesis of "All Gaming Laptop" would be faster than M1 gives you roughly 3.3% of the Marketshare. Not too far off 2%.
And all of that is before we put any performance number into comparison.
This is what I don't get.. why would you ever assume they meant counting by model? That's a nearly meaningless measurement. How do you even distinguish between models in that measurement? Where do you set the thresholds? The supercharged gaming laptops are absolutely going to dominate that statistics no matter what, because there's a huge number of models, lots of which only differ mostly by cosmetic changes. The margins are likely higher, so they don't need to sell as many of a given model to make it worthwhile to put one out. Does a laptop maker even have to actually sell a single model for it to count? How many do they have to sell for it to count? Does it make sense to count models where every part is picked from the best performing bins, so that you're guaranteed that the model couldn't count for more than a fraction of sales?
Counting by number of laptops actually sold is the only meaningful measurement, at least you have a decent chance of finding an objective way to measure that.
And I thought it was 100% obvious from Apples marketing material what they meant, so I really don't get why anyone is confused about this.
Not a single one will beat it in single core performance.
And their statement will have been through all sorts of validation before they use it so it's almost certainly not 'bullshit'.
That statistic from Apple is just as bad as those.
Not the same as "Faster than 98% of the cheapest OEM laptop available!".
Apple has not made pure fantasy claims in the past so why should they now? The trend has been clear. Their ARM chips have made really rapid performance gains.
At best we have some trite stats about single core performance but I’m interested to see whether or not this maps to reality on some much harder workloads that run a long time. Cinebench is an important one for me...
Every true tech nerd knows this is fucking impressive ever since iPhones started being benchmarked against Intel and every true tech nerd can tell that this is only going to get better. :)
No, it's faster than all those laptops, not just "fanless" ones. It's actually faster than several fan-using i9 models. And it has already been compared to those.
The grantparent talks about comparisons for GPUs...
