I doubt that. Almost certainly just driver issue since 8 Gen 2 has ray tracing support.
That's what Geekerwan said about Adreno 700 series, let's wait until real system arrives then we will know..

Did Qualcomm claim X-Elite comes with hardware RT support???

Are ALUs the same across different GPU architectures?

We know quite a lot about the the ALUs and architecture of Nvidia, AMD, and Apple GPUs, but there is almost no information about Adreno. A while ago I tried to look into it and I was not able to find anything useful.

That said, while different vendors pursue different strategies in designing GPUs, there is a surprising amount of similarity between how all these GPUs work (e.g. almost everyone uses 32-wide SIMD with interleaved instruction scheduling). I suppose that over time it has been discovered that some things work better than others, and GPUs are subject to a fairly well defined set of limitations.

Well well well.

I was expecting the X Elite's GPU to be much more stronger than Apple M2. Kinda disappointed.

And the M2 Max GPU is on another league

Yeah the GPU ain't up to much. Considering the M3 is about to released today and assuming it gets a bump in GPU performance, it will be slower than the M3 which is getting released today.

But to be fair, it's still a very nice bump from their previous efforts.

Wait...

The Adreno in the X Elite has 1536 ALUs?

So that's basically the same GPU as in the Snapdragon 8 Gen 3.

(With higher clock speed I presume)

The scores for the 23 W TDP configuration are much more impressive than the higher TDP version. Intel and AMD cannot catch it in CPU performance unless they up the core count of the big cores with their next mobile CPUs.

What's even more impressive is the iGPU performance. To basically match AMD, who have the most mature iGPU drivers, with a first gen product is really impressive. Granted it is just one game.
You are comparing old products to unreleased ones.

Wait for Zen 5 and Arrow Lake.

Also, once x86/x86-64 emulation gets involved, performance and battery life are going to tank. At the same time, nobody is going to port Windows software to ARM unless ARM has significant marketshare in the Windows ecosystem.

Linux, however, is practically a solved problem, and IMO is more exciting for me personally since most open source software should have native ports at this point thanks to the Raspberry Pi.

Speaking of which, my Pi 5 finally gets here tomorrow. 😎

This is in contrast to Apple.

A15: 5 cores
M2: 10 cores

Apple doubles the GPU core count going from the phone chip to the base laptop chip.

Whereas Qualcomm is basically using the same GPU with same core count in the laptop chip as the phone chip.

And of course the 1536 ALU Adreno in SD8G3 is a very formidable GPU (even better than Apple A17).

That explains the discrepancy

So I am guessing Qualcomm is going to be leaning in on dGPUs instead of taking the Apple approach of having humongous iGPUs.

I do not like this.

This wasn't the case previously.

Before the 8cx GPU (or the GPU in Surface SoC equivalent SQx) was roughly double what the latest 8/800 series Snapdragon was, so it seems like Apple actually followed Qualcomm's lead there.

Their DX12 driver is likely trash tier so I doubt that they are getting maximum out of it. Still, surprisingly good performance in Control all things considered (x86 emulation, drivers and probably zero optimisations from game side).

Zen 5 mobile won't be scoring 90% of AMD's fastest mobile CPU (the 16 core 7945HX) in Geekbench 6 MT at 20-25 W.

And Zen 5/ARL mobile are even further out than this Snapdragon in terms of launch window.
GB6 is a horrible benchmark for discussing MT performance. It scales exceptionally poorly with core count.

Also, if you're going to be making a comment about AMD and availability, have you even seen QC laptops? QC are severely worse than AMD in this regard of shipping practically nothing to the laptop market.

Find me one good 8cx Gen 3 laptop review aside from Notebookcheck. No major outlet has covered the thing, there's hardly any small outlets on YT covering it either. Can't even find one good gaming test for the iGPU either.

Maybe better in mobile gaming. But it’s not very good for anything more complicated (like compute). Check out the GB6 compute results for SD8G3, it barely catches up to A14.

I think it’s the result of different design priorities over the years. Apple wants general-purpose GPU cores that perform well on complex workloads. Qualcomm has traditionally prioritized mobile graphics over compute ability.

Not 3rd party but some users seem to love it: https://www.lenovo.com/us/en/p/lapt...kpad--x13s-(13-inch-snapdragon)/21bxcto1wwus1

Of course, these could just be Lenovo employees who got free laptops

Actually, the user reviews are pretty interesting to read. Some go in-depth on their use cases, like the one data scientist. Wasn't expecting that at all.

And found this: https://www.zdnet.com/article/lenovo-thinkpad-x13s-review/

On more performance-oriented tests, the Snapdragon just didn't compete. It took the ThinkPad X13s 89 minutes to run a big spreadsheet in Excel (a native ARM application), compared with 41 minutes for the current (Intel-based) X1 Carbon Gen 10. On the X13s, converting a large video using Handbrake took 3 hours and 38 minutes with the native version of the app; and 4 hours and 5 minutes in an emulated 64-bit version, compared with 1 hour and 55 minutes on the X1 Carbon. And a big Matlab model just simply would not run. Bottom line: this isn't the right machine for you if you run heavy-duty applications.

Based on the performance, I would say it shouldn't sell for more than $650 but going for above $1000.

It scales perfectly fine for the kind of tasks it is designed to measure which is much more relevant for the vast majority of laptop users.

Also, I didn't want to comment on availability.
So if you're aware of that, why would you make a comparison you know isn't a valid one? You know perfectly well that GB6 doesn't scale well all the way up to 16 cores, and that a few faster cores are better suited to the benchmark. Nuvia themselves are claiming ~25% faster than PHX in MT, and only 5.5% faster than the 13800H. Why not use those numbers instead?



Claiming it needs to be faster than a 7945HX in MT is totally irrelevant to GB6 performance.

I used to have same expectation as others about sales of Qualcomm's notebook; that's pretty sucks for its price. But that is referring to consumer notebook market. Consumer notebook market is hard to compete with existence of Apple, AMD and Intel. But it is another story about commercial notebook market; and I believe Qualcomm is targeting more on commercial notebook market. Commercial notebook market has about 60% of total notebook market share; and it is Intel's stronghold; even Apple and AMD have hard times to crack.

But I believe Qualcomm X-Elite series with 5G support would provide enough incentives for Fortune 500 to switch if Qualcomm passed the computability test. Below is the link about Citi news:


Corporate users are not sensitive about prices, and they are likely to buy in volumes, thus I am expecting Qualcomm will surpass AMD to become No.2 key player in commercial notebook market by end of 2025.

IMO the Cinebench 24 is a lot more impressive as it's a much more taxing MT test.

I just ran it on ma 8+2 M1 Pro work laptop and the MT score was about 819 points.

While the M2 Pro has 2 more small cores, it still won't reach anywhere near the Qualcomm scores:
  • 997 for the smaller reference design
  • 1227 for the bigger one.

Even M2 Ultra still scores around 1600 after all (2x CPUs on one package).

The single threaded results are good too.
  • The 4.3 Ghz design is the same as 13900KS
  • The 4.0 Ghz smaller design is on par with the 7950X

And while it's true, that these should rather be compared against the upcoming M3 Pro, Meteor Lake and Zen 5 - it's still a very solid result from the first implementation.

All of the competitors need to do a very good job with next-gen chips to really outperform it.

I would really like to see a power-unconstrained Desktop version as this also supports external GPUs. Too bad it's a pipedream for now.

EDIT:
Ok when closing everything I managed a 819 point run on the M1 Pro.
Thanks for the Cinebench 24 comparison. That's impressive indeed.

I think I'll start calling GB6's "MT" CT instead, as in "Consumer limited Test". GB6 does not contain a classical MT test score, of which people intuitively have the expectation of being able to fairly compare chips with vastly different amounts of cores. So any Cinebench version is better than GB6's "MT" any way any day.

Jon Masters seems pretty hyped about the design. And given he worked at Nuvia and knows Gerard Williams for a lot longer, this seems somewhat significant.

and more:

Jon Masters said:
Gerard Williams only knows how to be the best. If you take him on, you had better be prepared to lose. Not surprised that Oryon is dunking on the competition. That’s why we did NUVIA

Another random Gerard story: when he got married, his wife’s dress looked absolutely stunning. He sewed that dress himself, by hand, easily beating high end designers out there

That guy can’t be another other than the very best at everything he tries to do

And remember: they’re just getting started. Be prepared for insanely ridiculous gen on gen perf uplift

...

One more random Gerard story: he worked on many of the earlier 32-bit Arm holdings designs. In at least one case, he was still perfecting the design *two years* after it shipped. For no reason other than that he can’t stop himself from trying to make things better

Give that guy enough hours in the day, and the result is dangerous

I’ve witnessed him hacking on perf models at 2am on several occasions

The core really reminds me of Zen1. Hopefully they can also deliver on those hyphothetical large gen-on-gen performance increases.
