So... Qualcomm is in a very bad position right now.

They were hyping it upto be an M1 moment, but it has fallen far short of that.

Their CPU has failed to reach their power/performance targets.

Their GPU is lacking in featurset and is complemented by subpar drivers.

Their NPU is lacking in featureset and programmable software cannot be run on it.

In short, their IP stack is weak and has many problems. They'll have to invest significantly and work hard to fix everything. Will they move forward with the Quest for the PC market, or will they throw the towel?

So what you're saying basically is, "Charlie was right"

So to achieve the full performance of the X Elite chip in CB2024, we need to run it in a performance mode with fans blasting?

How then, is Apple able to get the max performance from an Mx chip in a passively cooled (~10W TDP) Macbook Air?

The actively cooled Macbook Pro 14" with M3, and the passively cooled Macbook Air 13" have pretty much identical performance in CB2024 IIRC.

The thing is, M3 consumes like 22W at max all core load, but the MBA chassis can only dissipate 10W....

How long does it take the M3 to run that benchmark? (serious question, I have never run CB so I have no clue)

One can claim "the MBA chassis can only dissipate 10W" but it can obviously dissipate more than that at least for a while, based on how effectively heat is conducted from the CPU to the rest of chassis, and the starting temperature of the chassis. If you knew the numbers it would be possible to calculate how long a CPU radiating x watts can continue to do so until the capacity of the chassis to absorb heat is reached. At that point the CPU would only be able to radiate y watts, i.e. whatever the number of watts is that can be effectively conducted off the CPU to the chassis, and the chassis is able to radiate to its surroundings (which is influenced by room temperature, amount of air movement in the room, the material the chassis is sitting on, etc.)

In short, if I tested an M3 MBA, sitting on a metal surface in a room air conditioned to 70F with an air register blowing down on it, running CB2024 immediately after turning it on after it had been off overnight, and you tested one sitting on a wood surface in a room at 78F with no air movement running CB2024 after you've been using it for browsing for an hour, we're likely to get different results.

Good points. Reviewers should do such a deep dive comparison of the M3 Macbook Air and say... the Surface Laptop 7. So far, all the comparisons I have seen are against other Windows laptops.

With all the people clamouring "where the fanless Snapdragon X laptops are", it would be good to make an investigation how the fanless Macbook Air works.

I think it is kind of funny that a few months ago people here were eagerly awaiting the Zen 5 and X Elite release, and all the talk was about how Intel and Apple are done for.

Here we are a few months later, after Apple did a surprise launch of the world's fastest CPU core in a 5mm tablet, Intel released unexpectedly promising information about Lunar Lake, and AMD and Qualcomm utterly failed to live up to what the hype machine was claiming.

So what was the response? Did everyone cool their jets and decide to wait for real information before driving the hype machine into overdrive? Heck no, there's already a Zen 6 speculation thread and one person out here claiming X Elite is just a "test platform" lol!
 
So I haven't been following the SDX Elite much, but trying to look for reviews and benchmark data there isn't much. Just read Charlie's post.. and, he's right? Seems like all the reviewers had to buy their own devices and MS/QC did not seed devices to anyone? Wow it just all makes too much sense. Now back to the chip, it really is underwhelming! Now I don't know why anyone would want to buy this unless you really like to beta test and pull your hair out in frustration.
 
I knew it!

See how bad Intel's beta silicon made x86 look in comparison?

Hawk point is much better and Strix point should be competitive though not holding my breath. Handbrake loves cache which the SD X has more of.

Anyway, now that he has tested an AMD laptop, I forgive you, Avram.

Is this a new form of cope?

yes. I don’t need another hype cycle.

isn’t AMD still 2 minutes slower? That’s still bad for non-beta x86 silicon. If AMD cheaps out on cache that’s too bad.

This review is way more in depth than I was expecting, even for Cary. Honestly a great review. Goes into proper depth on both the efficiency and performance modes, and compares all devices at the same total system power (with the display disabled to counteract the hungry OLED panel).

The gaming numbers are a total mess for SDXE so not even worth discussing, but the CPU power numbers are very interesting. If you haven't watched it, it gets a very solid recommendation from me.
