Microsoft claims, in internal documents seen by The Verge, that these new Windows AI PCs will have “faster app emulation than Rosetta 2” — the application compatibility layer that Apple uses on its Apple Silicon Macs to translate apps compiled for 64-bit Intel processors to Apple’s own processors
Faster than Rosetta2? 0_o

Do you guys think Qualcomm will pursue big SoCs (with big iGPUs and wider memory buses- ala Apple M Pro and M Max) ?

A bunch more Qualcomm CRDs with Snapdragon X Elite have appeared on Geekbench recently.

Why are these running at a measly 3.4 GHz?

(1) Do you guys think Qualcomm will pursue big SoCs (with big iGPUs and wider memory buses- ala Apple M Pro and M Max) ?
(2) When do you guys think Qualcomm will adopt chiplets? Intel and AMD are aggressively pursuing it. Apple does too (in a limited sense) for their gargantuan M Ultra chips.

Maybe a M3 Pro equal but M3 Max is clear no. M3 Max is entirely different class of SoC that only Apple can do because its sells a product not the chip.

Yeah a 256 bit memory bus SoC is probable, as AMD is also doing it (Strix Halo).

I envisioned it with my Snapdragon X2 Ultimate concept:

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

It's better for the planet.
How much energy is consumed producing your new laptop, then shipping it halfway around the world? All the plastics, microprocessors, metals that went into it all needed energy to produce. A lot of the time the most environmentally friendly option is to keep using your old system for as long as you can.

Qualcomm will not adopt chiplets for PCs anytime soon. Chiplets are still the future in some sense, and we’ll probably see variants become more suitable for very low power operation for sure, e.g. some GPU+IO tile and a CPU tile or whatever on a very low power interposer might happen eventually.

Apple only does chiplets for their desktop Ultra chips. The M3 Pro/Max do not use chiplets even if in theory they’d benefit cost wise due to their size — probably in part because they don’t think there’s anything suitable yet for the hit to power and they can afford the die size costs and sell directly to customers.

Another thing at that, RE: die size, is that Qualcomm is selling a mainstream premium part designed for power and energy efficiency. They aren’t selling an M3 Pro/Max with a huge GPU because they wouldn’t have the bus width for it (much less the use currently what with games on Windows or compute for Adreno, honestly what would you do with it?) and that market segment is too limited for Qualcomm/AMD/Intel right now save for games, whereas Apple can grab that from creators etc.

With LPDDR6 they (AMD/Intel/QC) could throw a bigger GPU onboard without using a bigger bus, but by that point they’ll have another logic shrink and speed boost with N3E/P if not N2 (smaller shrink there though) so it sort of levels out.

Lmao no. Why? LPDDR6 will give them 50-100% more bandwidth and that’ll be that for games and such. But relatively speaking it has to be an entirely different class of application and user to justify that and they need more volume and more niche software (or just gaming) support before that even comes close.

Nvidia later on will be the first Arm vendor to do a fat bus, if they do.

Exactly what I want to say about upcoming X-Elite G2, Qualcomm most likely employ 128-bit LPDDR6 for next gen monolithics SoC. With 200GB/s BW, it provides 50% more bandwidth which is enough for extra CPU and GPU cores manufactured by N3P...

If NV is using Intel 3 process only, I don't think IF is capable of MFG 128-bit LPDDR6 SoC...

As for climate change: LOL

This is such an small percent of energy differential by earth’s consumption, and ultimately what matters as much if not more is the power generation source. For ex: EV cars are more efficient on a joule basis per averaged mile of use. But you could reduce the gains for climate by fueling electricity that with coal or whatever. In practice this isn’t what is common or the way things are headed (nor is this an anti-EV screed) but you get the idea. Who cares about electricity consumption as long as pricing mechanisms remain. Focus on the source’s externalities.

Yeah precisely my thought too. The 12c I thought were pushing the bandwidth but even today at 136GB/S they definitely have room for a few more — and with LPDDR6 and N3P/E that becomes likely along with a bigger GPU.

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.

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.

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...

Well, if not a 256 bit SoC for Qualcomm...

How about a 192 bit one!!

Goldilocks zone (between 128 and 256!!!??)

Similar to M3 Pro.

Then Qualcomm can create a lower end 96-bit SoC die as well.
