the what.
A 4+4 with lower clocks would go for 8-10W SDP just fine.
Hamoa is 12 big chungus cores (at pretty fast o'clock), it was never inteded to be a 10W part.
It’s a 12 core that has somewhat better performance than M3/M4. I don’t doubt the 4+4 can go fanless, but won’t that be in devices that have no hope of competing in the premium thin and light space? They can keep the snappy UI and web browsing that single thread allows, but they will get crushed in everything multithreaded, won’t they?

Do you think we are going to see comparos with the Macbook Air, a Lunar Lake, and a 4+4 Qualcomm?

Just don’t expect huge gains moving forward. I echo the sentiment some others have brought up: we appear to be gradually hitting some kind of bottleneck, regardless of ISA.
Why isn't anyone doing a single core cluster containing two P-cores and four E-cores with shared cache because that could really reduce core to core latency and context switching latency?

What's the use of a 2P+4E cluster?
It would reduce the overhead of thread migration between the hybrid cores in case of mixed workloads (fire up the P-cores for quick bursts of ST workloads that finish in a few seconds and continue to do your normal long duration workloads on the E-cores that don't really need 100% CPU utilization).

Doesn't make much sense. That applies only to Intel style E-cores, which are in sufficient numbers and are utilised for MT throughput.

In Apple/Qualcomm CPUs, the E-cores are purely there for efficiency. High MT throughput workloads run on the P-cores.

Linus' video;

Highlights


Gerard Williams reference



Battery Life seems good.


Linus notes that any apps requiring AVX2 or games with anti-cheat kernels, will not run.

Also amazingly, Solidworks works (excuse the joke).

Overall, Linus is positive about the new wave of Snapdragon laptops, which is notable as this is not a Qualcomm-sponsored video.

This review claims Geekbench 6.2 "fails to launch" on this X Elite laptop. I've never heard of that before. Yet they have Geekbench 5 scores (1669 1T, 8618 nT). I don't know what happened to Notebookcheck here. Maybe something very weird at HP's business line of laptops? Surely not, though.

Battery life is also good, not amazing (IPS 60Hz); system idle power was nice, 3W - 6W depending on the brightness. Fan noise is much better than average.

I prefer reviews like that where they don't try to cover up the flaws with shiny marketing points.

Looks like QC may be making some heavy compensatory payments to all the OEMs who jumped on their bandwagon and then have abysmal sales. Either that, or the next QC hype bandwagon will have fewer players onboard.

Don't get me wrong. I don't want QC to fail but the hype was just too much and they were stupid enough to ignore the advice of experienced OEMs and went with their higher cost boards, adding to the platform costs. They will face even tougher competition once Lunar Lake and Strix Halo show up for the fight. The sensible thing for them would be to scratch their lofty ambitions and achieve mass market penetration through reasonable and lower prices than the competition. Otherwise it's going to be the chicken and egg problem for native WoA application/games developers (why should they expend extra effort for low sales volume?).

Ye but no.

If they hang all this AI blarg on it and that bubble eventually pops, it will impact Windows PC sales, but likely WoA most.
AI is never going away. It, in fact will be the only way the overwhelming majority of people will use compute. There is not much qualitative that can be done on current devices and Qualcomm doesn’t yet have the software stack to even reach current hardware potential.

Current Snapdragons will be able to do much more in a few months than they can now, the software stack is incoming. It will still be nothing compared to what devices in 2030 can do.

This is probably true, i.e., they could have avoided the (allegedly) mess. But this is very insensible of how the Intel business works.

Intel has a borderline abusive way of doing business. They use their well-established influence to essentially control, or at the very least highly manipulate, all the parts of this ecosystem (OEMs, sales channels, software developers). The price of their parts is not only high, but they had for many years purposefully pushed it to the limits to force OEMs to cut elsewhere (GPUs, for example. NVIDIA knows this very well) only to "rebate" afterward.

This is one of the factors AMD has never been big in terms of design wins, presence in big retailers, or presence on media/reviewers outside of the tech niche.
The sensible thing for them would be to scratch their lofty ambitions and achieve mass market penetration through reasonable and lower prices than the competition. Otherwise it's going to be the chicken and egg problem for native WoA application/games developers (why should they expend extra effort for low sales volume?).
If the leaks are real, their price is already considerably lower.

They are purposefully going for the premium tier. For the aforementioned reason, it is unlikely they are going to be massive in volume, so a budget part would only give them some limited brand awareness. If the smartphone business is any indication, they are better (for Qualcomm's scale) targeting high margin, low volume of the premium tier than battling for every last penny on the entry-level market. There, the mid-high tier is basically disappearing, pushing margins even down.

If emulation gets good enough, they will probably rely on it and call it a day.

I only hope their new parts reach out to close the gap with Apple. Even M1 is very good with Rosetta 2.

Lengthy video by Wendell discussing "what when wrong this time for Windows ARM".



Qualcomm had the privilege of seeing how others did it to at least not make some mistakes, but they still don't have a Dev Kit? Why?
Is like there's still no plan from both Qualcomm and Microsoft. Why?

He has a point with Microsoft's magic thinking about ARM being what they need to compete with Apple.
They are aggressively ruining Windows regardless if it runs on x64 or ARM.

I do not contend that AI will go away, only that the overhype of it simply to sell more computers with product offerings of dubious value to the consumer is likely to come crashing down at some point.

Snapdragon 8G4 will most likely stick to LPDDR5X, and not support LPDDR6.

That means 8G4 has the same 76 GB/s memory bandwidth that 8G3 does.

Considering that 8G4 is supposedly getting a 50% faster GPU than 8G3, the architectural changes of Adreno 830 must be significant to deliver that within the same memory bandwidth envelope.

Snapdragon X2 speculation/concept v8

You may be wondering why I have based the X2P/X2E on a huge 200+ mm² die.

Well, I think it will be necessary for Qualcomm to stay above it's rivals.

Lunar Lake is a 140mm² N3B + 40 mm² N6 product.

X Elite is a ~175 mm² N4 product.

Panther Lake is coming in late 2025, and that's what X2 Elite will have to compete against.

Panther Lake will certainly exceed 200 mm² combined die area, and maybe even >250 mm², due to the significantly upgraded CPU, GPU and NPU.
