It only matters for servers. If everyone using an ordinary PC switched to an equivalent Apple/Qualcomm ARM CPU (i.e. not those of you with Threadrippers and the like that don't have ARM analogs) it would be a rounding error on a rounding error.

You want to save the planet, develop more energy efficient ways to produce cement. That would prevent more CO2 emissions than shutting off every computing device on the planet.
Yep!

That's the whole point of a 256 bit bus. It's an entirely different class of SoC.

AMD is doing it with Strix Halo...
AMD has a gaming market with full compatibility, great drivers, and will be using glue & chiplets for cost reasons. This is also a limited market and it won’t make sense for Qualcomm to go after that with their competitive advantages (or lack thereof).

I will also guarantee you Strix Halo will choke at lower (below 20-30W) power and idle operation in a way a monolithic and deliberately designed for low power Mx Pro does not. For AMD that’s fine, and half the chuds buying Strix Halo won’t care and think battery life is for wusses or whatever. For Qualcomm with a weaker volume target, weaker gaming proposition, and without Nvidia’s AI prowess or anything of that sort, I just don’t think it’ll happen.

I don’t think AMD will sell an insane amount of 256-bit bus parts either, it’s a premium thing. But AMD knows that, and it makes an order of magnitude more sense for them as a premium niche part than with QC even 3-5 years from now.

I am not fully convinced X Elite G2 will have LPDDR6.

It all depend on the timing. When will X Elite G2 launch, and how LPDDR6 availability be by then.

If it's not LPDDR6, it will quite likely be LPDDR5T/5X-9600 which is a step up from the LPDDR5X-8533 utilised by X Elite.
Honestly I would love to be wrong but the rumor was X Elite 2 launches in 2026 H1. It can’t be 2027 or they’re unserious but 2026 would be about 18-24 months from release which is fine.

That said if the 8 Gen 4 is rumored to have LPDDR6 compat and the 8 Gen 5 as well then yeah a 2026 X Elite 2 will have it, it’ll just (maybe) have LPDDR5X too probably.

The idea is that QCOM isn't doing a Halo SoC like AMD. Very unlikely that they'll move from a 128-bit memory bus. Bandwidth improvements will come from LPDDR6 or LPDDR5T, whatever is available for Pegasus product cycle.

Though idk. Maybe it launches 2025 but I doubt it
Adreno 830 would be a big uplift over using the Adreno 740. New uArch, higher performance, and better perf/W.

Ehhh. I am not sure if that's fine. X Elite is enough to dig the trench but not sufficient to hold it. Next gen Intel/AMD parts will certainly be more performant than X Elite, and they are coming in late 2024/early 2025. Qualcomm should iterate fast.

I'd like Qualcomm to release X Elite G2 no later than 2025H2, same time as 8G5. It makes sense, as 8G5 will utilise N3P node and Oryon Pegasus CPU core.

Arrow Lake is terrible garbage fwiw and while Exist50 isn’t here he’d explain if he were, and it matches what everyone else has said. Not worried about that. Performance will be “better” barely and efficiency again still crappy and it’s an expensive mess.

LNL is redeemable ish as I explained elsewhere but probably isn’t going to be that great, it’ll be good relative to anything else Intel has or AMD has for the 5-20W range and immediate legacy compat + Intel design wins influence means that it’ll sell. It will just sell less than they would if they hadn’t, you know, lost Apple, let AMD come back, and have Qualcomm now lol.

I doubt LNL will match QC in peak performance on MT even for the 10c part and at best they might get close for ST if they have a 4++GHz SKU and QC has a Plus SKU that tops out at 3.8GHz. Efficiency much closer to QC than MTL but still skeptical. They need a literal 50-55% performance improvement iso-power in ST at multiple points.

Strix will definitely outperform the X Elite though and while being compelling in some ways, and I bet an energy efficiency boost.

But I’ve also heard the downmarket X Plus with 10c and slightly lower clocks will be pretty inexpensive (for a premium part) fwiw and I don’t think Hawk Point stands a chance agains those.

I agree 2025 H2 should be the time for the X Elite though ultimately, but if they can pull off Q1/2 in 2026 that’s not the end of the world.

What QC needs for gen 2 and what I expect:

N3E/P
A power and mild IPC tweak to the big cores (say single digits IPC), maybe slightly (.2-.4 GHz?) higher clocks.
Real littles for background tasks and an area efficiency boost.
A wider faster GPU, pretty straightforward
Same for the NPU obviously.


The thing is so good and modern that this alone would be enough. Maybe PCIE Gen 5 support.

I think some here are underrating just how much better the X Elite will be from an efficiency standpoint and with that, battery life and *responsiveness* (you can ramp to higher frequencies without killing the battery, or the same for less). People notice that.


This slide hasn’t made the rounds yet, but it’s recent:

Look at the 58% and 89% additional battery life Qualcomm gets for web browsing and Youtube over the Core Ultra 7.


They do better with local video playback too, about 40%, which is still humongous. But local video playback is also less common than streaming, and it’s ideal for some chips because it pads over the weaknesses in their CPUs — they just gate them or run minimally — but most people aren’t using laptops for local video as much as they are web browsing and mixed light loads, streaming, or editing code or video with a final compilation, and a lot of random bursty ST.

(Also: Ignore the Teams video conferencing lmao, as I suspect that’s using the NPU for something QC exclusive.)


EDIT:

I think they just measured the SoC/package + DRAM and VRM's directly for the entire duration of the tests, so it really is chip-to-chip - this is Andrei Frumusanu doing it and he has the tools to do so. They only mentioned the specific laptop - the Asus Zenbook 14, because of it's RAM/wireless/etc choices and any possible packaging stuff.

So forget this below:



[[[The Intel Core Ultra 7 155H laptop used here is the Zenbook 14 UX3405, with a 3.2K OLED display (variable refresh) and a 75Whr battery, found here or here. Notice this laptop isn’t exactly doing poorly battery life wise. Qualcomm has two Snapdragon reference laptops, and most *likely* (if they’re reasonable which lol) they are using the Thin and Light B config for the comparison, which has a 14.5-inch OLED 2880x1800 display, and a 58whr battery.
So conditional on Qualcomm using Laptop B: the X Elite with a similar OLED display is running up the score on an Asus/Intel laptop with a decent reputation for battery life — and the Qualcomm laptop even has a 22% smaller battery.]]]




So Qualcomm probably isn't at any battery disadvantage for the test, nor are we dealing with display differences for it.

But it still looks unreal for QC - this is sort of similar to how Apple has looked or AMD when Intel was on Alder Lake. And here, MTL wasn't even bad for battery life, they're close to Phoenix laptops on a lot, even if the responsiveness is behind or the efficiency under load is.

One more reason why people should consider moving to power efficient ARM platforms.

It's better for the planet.
This person might be part of Snapdragon Insiders as he is really hyping up the product. I would avoid these people for they have extreme biases and very outlandish opinions. Qualcomm promotes this "membership".

These numbers are seriously impressive, specially the latter 3 (Web Browsing, YT Streaming/Streaming and Videoconferencing), which are the most common workloads a laptop PC will face in the hands of the average user.

And MTL isn't a terrible SoC wrt battery life either, which makes these even more eye opening😯.

If we compare with the little amount of info we have so far from LNL (40% scenario power reduction), indeed it will be a tough battle for LNL to match.

Exactly.

I think Teams is possibly kinda juiced and they added a bunch of video effects and QC's NPU just blew it out of the water on power efficiency (QC's is certainly much larger/wider lol) even if MTL's takes place offline. I mean sure that's valid but not as interested in it, people are plugged in quite often when video conferencing anyways.


But yeah, the web browsing and YT streaming is what really shows it. This is ridiculous. I bet the X Elite was more responsive too.

Yep. Not far from Phoenix at all on a lot of stuff in similar laptops lol (but loses under load for efficiency).

Yeah. I think it'll get close ish in some ways but idk.

Indeed. I myself once enthusiastically joined the Snapdragon Insiders discord server once, hoping to become an Insider myself!

But I left. The major reason being that we couldn't discuss any leaks/rumours there!

So it's just essentially a company curated fan club.

Aren't the leaked LNL SKUs so far topping out at like 3 GHz?

Also yes, Intel needs to make a massive leap with LNL to catch upto X Elite efficiency;



I am skeptical they will be able to do that.

ARE YOU INSANE?**

They need a major IPC increase. We are talking double digit gains. X Elite G2 will be competing with Apple M5, Zen6 and Panther Lake. They'll be needing a performance uplift in the range of ~50%.

M5 and Zen6 will most certainly exceed 4000 points in GB6 ST. Qualcomm has to match/exceed that.
Real littles for background tasks and an area efficiency boost.

Same for the NPU obviously.
Yes, we want FAT GPUs. But the rumour says that X Elite G2 will simply use an overclocked Adreno 830....

**Please don't take offense at this sentence.

Panther Lake
No offense, but PTL will be probably be a class below Z6 and M5, so QCOM won't be worried with it. If Lion Cove already won't be competitive with Z5 and Snap X Elite, much less will be Lion Cove+/Cougar Cove. Unless there's some serious low hanging fruits on Lion Cove design that can be leveraged.
Adreno 830
TBH QCOM has been increasing the GPU size gen over gen. 8G2 was 1536 ALU, 8G3 was 1792 ALU. 830 might as well be 2048 or even bigger.

What matters is the performance at the end of the day

3DMark Wildlife Extreme
Adreno 740 (8G2) : 22 FPS
Adreno 750 (8G3) : 32 FPS
Adreno 830 (8G4) : 44 FPS

X Elite (80W) : 44 FPS
X Elite (23W) : 40 FPS

Apple M2 : 40 FPS
Apple M3 : 48 FPS
Apple M4 : 60 FPS??
Apple M5 : 75 FPS??

Yup, feel the same. Especially skeptical they’ll be able to match it (the GB6 ST performance) at 2-10W. I will give them points if it’s really close, but I’d just be surprised.


We will need Andrei to do a comparison or someone from the wall minus idle with TDP limits or something though. If it gets too close QC may not publish anything, but Andrei will probably be straightforward in other forums about where it does ok.
