That could be, except when throttling is considered. @nikidimi says above that the 4800U loses 25% performance when it throttles, putting it on a par for multi-core with the actively cooled M1. That's a big advantage of a lower TDP. (One reason I asked about a laptop with the chip rather than just the chip earlier is that in a particular laptop it has to be effectively cooled, etc.)As for the reviews, it appears Renoir (especially in its 35w-45w variants) remains the highest performing CPU in multithreaded performance, and the M1 has a big edge in single thread. The 25w version of 4800u still seems to be faster in multithreaded performance. Of course Renoir has a higher power draw, but the M1 is on 5nm and on the MacBook Pro/Mac Mini is using seem to use much more than 10w. ?
The 4800U can be set at different TDP's.That could be, except when throttling is considered. @nikidimi says above that the 4800U loses 25% performance when it throttles, putting it on a par for multi-core with the actively cooled M1.

is the 4800U actually locked at 15W? Usually, those chips can go higher than the TDP numbers for some amount of time.And that's with a 15W locked 4800U, which is a much more apples-to-apples comparison against the M1 which is probably drawing at 15W too (the Cinebench R23 power draw #'s people are saying adds up to ~15W as well).
Right, but even the 15W version actually runs a lot hotter than that, according to reports here (as does the M1 in the actively cooled housings), so throttling may remain a problem. In comparing the M1 Air to the M1 MBP, the throttling only showed up when R23 was on a loop, so it might not show for the 4800U either in the results you link to.The 4800U can be set at different TDP's.
If it throttles, it's likely because the higher TDP setting isn't matched by the cooler in the laptop, which is definitely a problem with a lot of OEM's out there.
Anywho, now look at this: https://www.anandtech.com/show/16252/mac-mini-apple-m1-tested/2
The 15W 4800U beats it in MT at 9,286 against the 7,833 of the Mac mini at Native in Cinebench R23.
And that's with a 15W locked 4800U, which is a much more apples-to-apples comparison against the M1 which is probably drawing at 15W too (the Cinebench R23 power draw #'s people are saying adds up to ~15W as well).
And this is Cinebench R23, which runs a lot longer and thus thermal throttling can affect things more if cooling can't keep up.
Either way, it's clear that Intel is toast. AMD already took the mobile performance crown this past year, and just took the desktop performance crown away, and now Apple is adding fuel to the overheating Intel CPU fire.
And, most impressively, the M1 MacBook Pro used extremely little power to do so. Just 17% of the battery to output an 81GB 8k render. The 13” MacBook Pro could not even finish this render on one battery charge.

It is not, see this chart from another Anandtech article:is the 4800U actually locked at 15W? Usually, those chips can go higher than the TDP numbers for some amount of time.
Two things: one, it depends on if they lock it or not. 'Normal' operation allows it to boost above 15W, yes, but AMD is pretty liberal allowing people to set target power consumption. For instance, you can set the 65W 5600X (which can draw a max of 88W stock) to "just" 65W - you lose 2-5% in performance but consume 33% less power. You can even set it down to 45W or lower - it's actually a great illustration that power and performance don't scale linearly.It is not, see this chart from another Anandtech article:

Other part is that it also comes down to how long CB R23 runs then, and if they ran it multiple times.
Of note, Andrei of Anandtech, on Twitter, said he saw 15W of power draw on the M1 - but he wasn't sure if it boosts above that or not (and thus behaves like the CPUs above). He did see 21W in SPEC, so there is clearly headroom there.
It is set by the OEM (or by the user in the UEFI for those that have it unlocked).
I know TDP is confusing, especially since everyone has their own definition - Intel straight ignores it, AMD adheres mostly to it but lets you go above it (like the 65W TDP 5600X can go up to 88W of draw), whereas Apple is unknown (Anandtech showed 26W active power draw in compute MT thread, 21W in SPEC, and 15W in CB R23) so it's obvious Apple isn't strictly adhering to a 10W or 15W TDP either
Unfortunately, reviewers have to be VERY specific about it or else it's not easy to compare - which is why we're seeing so many different takes today, it seems.

Yeah, the problem is that the few reviews we have today are either pretty amateur-level ones from tech tubers or only initial looks like from Anandtech where they are few on details.
I'm waiting for the notebookcheck one since they run these things in loops and do actual apples-to-apples comparisons
Either way, from the initial power numbers, Andrei@Anandtech saw SPEC was able to pull 21W from the CPU cores only, so the CPU is clearly not just a 10W or 15W chip.
apples-to-apples comparison is hard to do with Macs. The mostly argued offerings from AMD are not officially available under macOS, and M1 Macs cannot install Windows. Comparing with Intel is boring as M1 is better than everything Intel has to offer in the same form factor. By the way I personally do not like the idea of installing Windows and doing benchmarks for comparison as the numbers are only useful when using windows on a Mac.I'm waiting for the notebookcheck one since they run these things in loops and do actual apples-to-apples comparisons

The echo mode on 65w parts decrease the TDP to 35w level if I remembered it correctly.5600X was my own benchmark on my SFF with a power meter
Look up Eco mode for Ryzen processors. You can actually see this with the older Zen 2 CPUs too. Here is the 3900 (OEM non-X variant) down-rated to 65W:
AMD Ryzen 9 3900 Review: a Taste of Eco Mode
Pre-built systems just took a big step forward.www.tomshardware.com
It draws a whopping 55W less than the 3900X (90 vs 145W) with only small single digit % drops in performance
Here's a video where Optimum Tech benches the processors in Eco Mode and shows difference in temps and performance:
Apple has comments on their site saying at what circumstance M1 is 3x faster. Like Xcode compiling comparing to an i3-8100B, M1 is 3 times faster(It is easy to verify, people having 10-core iMac Pro claim M1 is faster, people having 12-core iMac Pro claim M1 is on par). You can still argue that compiling runs only for a couple of seconds, but I don't personally think Mac Mini has Thermal problems for M1, this is more likely a problem for MacBook Air.Well then a lot of that makes the point of saying "M1 is 3x faster than Intel offerings" pretty moot. And there are Ryzen hackintoshes, so it's not as hard to compare as you'd think.
Moreover, the point was methodology. If a single Cinebench run is all that is used, we won't get the same answer as if we did a 30 minute loop for every CPU tested. A 30 minute run is likely more representative of someone doing rendering or music production or code compiling than say a benchmark that runs for 20 seconds

Getting past 7000 may be where the trouble is ...My laptop's 4700u can boost to 30+watts package power all day long. It is definitely more than a few minutes.
In the battery saver it is locked to 15 watts and I get 4800 MC in CB23 compared to 7000 MC in performance mode.
That could be, except when throttling is considered. @nikidimi says above that the 4800U loses 25% performance when it throttles, putting it on a par for multi-core with the actively cooled M1. That's a big advantage of a lower TDP. (One reason I asked about a laptop with the chip rather than just the chip earlier is that in a particular laptop it has to be effectively cooled, etc.)
Yes, we are making a lot of assumptions here. I think that 4800U at 25W is capable of boosting to ~35W and that's when it reaches 10000. If it's set at 15W, it's going to boost to only around ~25W and then it's reaching 7500 (or if set to 25W and it's throttling down). The M1 reports around 15W as @Gnattu posted. So the M1 is the fastest CPU below like ~20W and it's capable of achieving the same performance with 25/15W = 40% less energy, which is quite impressive.Unfortunately, reviewers have to be VERY specific about it or else it's not easy to compare - which is why we're seeing so many different takes today, it seems.
Apple doesn't claim to outperform the peak performance of the mystery chip, only match it. If the AMD throttles during testing, that may be why the cooler M1 matches it, as explained above. The figures do fit that scenario.All chips throttle, I think the point of the discussion between you and I was I was saying these ”Latest PC Laptop chips” Apple was referring to are not from AMD. The M1 at 10w isn’t outperforming a 40w Renoir.
