Wasn’t aware that Apple started to disrupt the market of custom made baking molds by moving to silicone… 😂🤣🥹Unless you are worried about the lack of silicone in the world, you should instead ask does it work well?
You’re still looking at it through the glasses Intel/AMD would prefer you use. It’s more “Why would I NOT want my low end to have the same single core performance as a desktop chip?” People buying i3’s, do they WANT to use a far inferior chip to the top end? No, but that’s all that’s available for them to use. It’s better for users because the macOS system they buy today will be more performant than the last one they bought of that type. It’s worse for users that, instead of looking for a more performant macOS system, are looking for wattage and heat numbers that match Intel. Luckily for Apple, the vast majority of folks aren’t looking for wattage and heat production to match Intel, they’re looking to check their email, surf the web, check their social media accounts, edit some pictures/videos, etc. Also, fortunately for Apple, they only have to sell about 20 million Macs in a year to be profitable enough to keep making them. I’m guessing it’ll be pretty easy for them to find 20 million folks that aren’t closely focused on their system’s heat output.Why would I want my desktop chip with room for much more thermal management to have the same single threaded performance as my phone? I understand how that’s easier for Apple, because they have less designs to manage, but how is it better for me? Perhaps Intel cripples their low end part to protect their high end, but Apple is probably limiting desktop performance by limiting to what can be done in a phone.
Yeah, but now you’re talking about a very small group of people, not the masses buying current laptop Macs (80% of all the Macs Apple sells). And, as things that are possible cross platform have been faster on Intel for quite awhile, there’s very likely not many in that small group (if any) that are still using Apple today.Apple still competes with other PC vendors. Obviously some people will make some compromises to run MacOS and keep their familiar workflows, but in the end people have jobs to do and if Intel can do those jobs significantly faster then they will leave Apple— just as people are leaving Intel now to move to the M1 series laptops.

It seems not...the Mba will run the same as this 13" Mbp...since Apple apparently is limiting the cores around 3.2ghz and the temp are let to reach 100-104C (so the fan was kind of useless here)Imagine all those people getting MBAs with M2, they'll be able to cook bacon.

Not quite, as was mentioned, the MBP throttles as the fan curves seem to be broken. As soon as the reviewer fixed that, the MBP performed as expected. However, an MBA will not have a fan to help once the entire thermal system soaks in heat.It seems not...the Mba will run the same as this 13" Mbp...since Apple apparently is limiting the cores around 3.2ghz and the temp are let to reach 100-104C (so the fan was kind of useless here)
So the Mba will run almost exactly like this, 100-104C 3.2ghz in full load with a body that is around 40C
But we still have to wait and see ourselves
Yes, I'm fine with that. A small reduction in performance once in a while is worth the tradeoff to not have a fan. Don't do a lot of sustain processing tasks on my MBA now.Not quite, as was mentioned, the MBP throttles as the fan curves seem to be broken.

Does it throttle? From what I’ve seen the performance doesn’t vary with fan speed. Perhaps a longer test would cause throttling, but nothing in the Max tech video showed that.Not quite, as was mentioned, the MBP throttles as the fan curves seem to be broken.

The video review did state the fan curve was broken on M2. So the fan was not raving up as it should. When compared to the M1, the M1's fan rev'd accordingly.Does it throttle?

I like Max tech’s videos, but I’m not sure they’re qualified to judge whether the fan curve is brokenThe video review did state the fan curve was broken on M2. So the fan was not raving up as it should. When compared to the M1, the M1's fan rev'd accordingly.
That said, performance kept on going perhaps on the premise that the CPU was going to get cooled down but it actually wasn't.

Well, given that the fans kicked in until the M2 reached 100* then yes, I'd say it was broken. A fan curve should start reving up fans as the CPU gets hotter, not until it reaches 100*. That is one way to rapidly kill silicon.I like Max tech’s videos, but I’m not sure they’re qualified to judge whether the fan curve is broken
If performance continues despite temperature and fan differences, I don’t think it can be called throttling.
I’m pretty sure this has been discussed here before. I think @leman had some information? In any case iirc it doesn’t kill silicon in any meaningful way.Well, given that the fans kicked in until the M2 reached 100* then yes, I'd say it was broken.

Well, it does. I can't remember which MacBook Pro was it, but it suffered from issues from the heat generated which detached the GPU's BGAs.I’m pretty sure this has been discussed here before. I think @leman had some information? In any case iirc it doesn’t kill silicon in any meaningful way.
We’ll see what happens with software updates, but they might just be comfortable with the M2 reaching those temps because they have the data and know it’s ok.
It can do a lot of things if the device doesn’t take some action to stop the heat build up— right up to and including letting out the magic blue smoke.Well, it does. I can't remember which MacBook Pro was it, but it suffered from issues from the heat generated which detached the GPU's BGAs.
Heat doesn't "kill" it silicone chips, it just allows them to desolder.
that was mostly the boards with Nvidia GPUs and probably one reason why Apple never went back to them again.well Apple has had a history of quite a few logic board replacements as they always favored silence and sleek design above sane temperatures, so...
Yes, a laptop Apple Silicon chip that outpaces most of the desktop chips produced today. Which really shouldn’t be a situation that exists. The current huge disparity in low to high single threaded performance in non-Apple Silicon processors shouldn’t be acceptable. Multithreaded, sure, because more cores=more performance. But, single core performance across the line should be what people expect. I’m sure AMD and Intel will continue to have their way, though, and, get folks to continue to accept “mobile just can’t provide good performance unless we put in a desktop part”.So your MBA has the same single threaded performance as a desktop because the desktop is using a laptop chip, not because the laptop is using a desktop chip.
You know the number one system those first time Mac buyers bought? The Air. Not REALLY folks that are desiring for their systems to generate more heat and consume more power. And, the PC/Windows world won’t leave mobile AS in the dust as, remember, PC/Windows has chip vendors telling them “you can’t get single threaded performance like the top end in a mobile system (ignore that Apple stuff)”. Where the PC/Windows world will ALWAYS beat the Mac is in the highest end bleedingest edge systems pumped with power and liquid cooling. Fortunately for Apple, that’s a fairly small market compared to, say, folks that just need to send email and edit pictures.The M1 brought a bunch of first time Mac buyers to Apple. Why? Because it’s a superior chip and users want what an Apple laptop can provide. If the PC/Windows world starts to leave AS in their dust, I expect those people to go back, along with others. You’re implying as much when you say Apple needs to keep beating their own previous generation. Why? If those users are chained to MacOS, they don’t need to beat anything. But they‘re not, and they’re not stupid, and if the system they’re using starts to fall behind the curve, they’ll abandon it. As I said above, some people, such as myself, will put up with some compromises because I appreciate the benefits of the Apple ecosystem, but I have a limit. Apple has to keep pace, they can’t be unconcerned if Intel starts to outperform them as you suggest.
Well, yes, that's also true. Once that magic smoke happens, the chips is completely dead.It can do a lot of things if the device doesn’t take some action to stop the heat build up— right up to and including letting out the magic blue smoke.

Apple, related to performance from this point forward, only has to perform better than the last Mac released in that form factor. There is little concern within Apple if the mobile systems they create (which are most of what they sell) doesn’t beat Intel’s bleedingest edge desktop systems pumped with power and liquid cooling, it really doesn’t matter.
Do you somehow think that I’m saying the laptop chips should get hotter? I feel like I’m being quite explicit that laptop and desktop chips should be different and optimized to their form factor. Apple taking your advice to not worry about what’s happening at Intel, AMD, Qualcomm or anywhere else will doom the Mac to being a toy.You know the number one system those first time Mac buyers bought?

Haha. Must be an Intel groupie.Imagine all those people getting MBAs with M2, they'll be able to cook bacon.
That remark aside, it seems I was quite right when it comes to the power draw and heat generation.
Apple didn't self-report 18% single-core, that number was explicitly multithreaded.I was using Apple's self-reported 18% single-core improvement over 18 months to get the ~10% number, but with the official Ars Technica review out with actual GeekBench 5 scores (what I was comparing the iMacs with) it looks like overall single-core gains on that specific metric are indeed ~10% from M1 to M2.
Catch up with alder lake? So funny. Alder lake sucks power to achieve what it does, no offense but Intel groupies need a reality shot. No doubt alder lake is good for a high power chip, it’s small gains over m1 were cool, but m1 was 2020 and still much lower power than alder lake. Now m2 is right in line, no doubt next version of high power Intel chips will probably surpass m2, but so?I was using Apple's self-reported 18% single-core improvement over 18 months to get the ~10% number, but with the official Ars Technica review out with actual GeekBench 5 scores (what I was comparing the iMacs with) it looks like overall single-core gains on that specific metric are indeed ~10% from M1 to M2.
Yep, they definitely played some long-overdue catch-up with Alder Lake, but given how much they increased TDP to achieve that I highly doubt that rate of improvement is sustainable. Intel's track record over the past 20 years is to release major architectural improvements with huge performance gains (Core 2 Duo, Core i3/i5/i7) and then make incremental improvements over the better part of the decade until the next architecture shift. Unless they've got some serious tricks up their sleeve, I don't expect the next few generations of Intel CPUs to break from that pattern.
Yep. You also get 5% more headroom to increase clock speed for the same power with TSMC's N5P process compared to N5 in the M1/A14. Apple ramped up the clock speed a bit more than 5% though.These aren't constant. They are up to. In short, in certain mathematical operations they can reach up to 18-20% and up to 35% GPU performance per clock cycle. Across the board you're more likely to say, 9% IPC improvement over M1.
