This is Nintendo... There's precedent for them leaving whole sections of SOCs dark...

They will want a HIGHLY determinant power profile first and foremost. They MIGHT enable a docked profile that pushes up to the thermal limit of the platform as well.

In all fairness, the Steam deck (Zen 2 at 3.5ghz - proxy for PS5/XSX) really isn't that far ahead
30% in the age where we say 20% gen on gen improvement is a lot, hmm.
and there are other A78 configurations at similar frequency which gives better results...
But they won't end up in the Switch. Probably the differences are down to cache layouts.

In the context of Switch 2 though? 30-40% difference in CPU performance shouldn't be a dealbreaker in terms of porting PS5/XSX games, given the inherently lower graphical/framerate targets (or indeed PS6-gen games given those are unlikely to have super elaborate CPU setups) . Considering what the Switch was able to get later in its lifecycle (Doom/Witcher 3 etc).

Well, I remember people complaining about Pokemon frame-rates on original Switch. I also looked up Witcher 3 on Switch and well, the crowd density in cities compared to PC doesn't look hmm, good Of course you can argue the game works, and the number of NPCs in the city doesn't influence that, and technically you will be right, but for some the it might hurt immersion, etc.

Yes, I get that Switch is sold by 1st party games and they don't chase visuals, but I personally would expect hw that would give confidence it will be able to last 5-6 years supporting something else than 1st party titles. Probably the reason I am done with buying Nintendo HW. I miss some of the games, and honestly would prefer them to turn into "software house" and release their IPs on other platforms. It's not like current midrange smartphones would be unable to handle proper Pokemon game or Mario, not to mention PCs and consoles.

Comparing to a (high-end) PC is just gonna end up badly for pretty much any Console though, let alone a mobile one. The point of comparison should be with contemporary consoles, it's not like the PS4/Xbone were great on the CPU side themselves, nor is the PS5/XSX circa 2025.

Given that the Switch 2 uses Ampere architecture with inbuilt DLSS, combined with possibilities for DLSS 4 back-porting (as per Nvidia). It should at least have the featureset to stay relevant for the rest of the decade, especially given that diminishing returns re graphical fidelity and Moore's law is far more prominent this decade than the last.

I never said I compared to a high-end PC. I played this game on a laptop with i5-4210H and gtx 950 and crowds looked better than on Switch.

Well, I might have been misunderstood. But let's compare to XSX. At the time of release, it was lagging the PC market by 1 gen (Zen2 derivative vs Zen3). Switch 2 will lag the "state of the art" by 4 gens when it will release. And I am not counting the fact we have X cores now. So yes, XSX is not great on CPU front, but still usable, as Zen 2 is still usable CPU, 5 years after release. Will we be able to tell the same about Switch 2? Only time will tell

Switch 2 will NOT be judged, 7 years from now, on the basis of its SOC. It will again be the games. Mostly 1st party games.
Yeah, some people say "oh it would have been so much better if it had a better SOC", but even most of those still agree it's pretty great.

Considering what they were able to pull out from Switch 1, visuals will be fine for what it is.

For the kids using a Switch it's also really famous nearly 8 years later for some absolute crap 3rd party games and ports. And the Switch 2 is shaping up the same way.
That doesn't matter for the legacy because - as you said - it'll have the Nintendo bing bing wahoo games. But it can hurt its "one gaming device and done" appeal. Maybe DLSS can save them this time.

Even taking aside that as a function of high fab costs and high margin business elsewhere, the hardware shift between next console gen and current is almost certainly much less than PS4/Xbone-> PS5/XSX (see how underwhelming the PS5 pro is spec-wise) , which should help with those porting issues... Nintendo never really marketed the Switch as a 'one gaming device and done' deal anyway, nor could it credibly do so given how much 3rd party stuff isn't gonna be on there.

It is part of the appeal of a dockable (handheld and console) with an adaptable control scheme. If could do everything well if only Nintendo could throw 3rd party developers a bone.

And it does have an impact. E.g. when the Fortnite port is so bad that kids rather play on their parent's phone. I really rather they use their Switch. That's the point of it to me.

But I digress since it isn't an A78 problem. It's a Nintendo problem.

I hate to be that guy, but this thread was supposed to be for discussion about future or newly announced ARM Ltd CPU cores.

Can we split off the Switch 2/A78 talk to another thread?

i dont know if this has been posted here but 8xA78 has better efficient than steam deck, so at reasonable power switch 2 will be better than many x86 handheld.
I suggest to re-evaluate this opinion. First by looking at the attached graphs. Second by translating the tweet (courtesy of google translate):
Hidden concerns of NS2 platform: CPU performanceAs a game console platform, NS2 will most likely have to plan power consumption allocation and corresponding frequency according to the worst case because of the CPU's pursuit of determinism. The performance gap between CPUs in different modes should not be too large. The power consumption limit of handheld mode will drag down the CPU performance potential of dock mode.If 6-8 cores can only run at 1GHz, the overall CPU performance will be inferior to that of SteamDeck at 2GHz.
So yes, Switch2 might be able to clock lower but graphs do not show that it would have better perf/W ratio than competition, quite the opposite if we allow at least 1W per core.

To stay on topic, do we ever get any leaks about new ARM designs? x64 leaks quite often but I haven't seen anything about x930, or x925, x3 etc in the past.

Still 4+ months to late May when they usually announce the annual IP line up.

The talk about X925/Blackhawk prior to May 2024 was pretty unusual for ARM.

They are usually pretty silent between IP announcements.

Hmmm.

Just went looking around and found a deleted post on reddit claiming that X930 has a 12 wide decoder.

ARM just shooting from the hip at this point, from X1 -> X925 is already an insane progression from 5 -> 10 wide as it is.

I'm sure Qualcomm deciding to do a custom core themselves has nothing to do with this...

Actually probably not.

QC has historically already had 3 custom cores before Oryon.

2 for v7-A, and 1 albeit short lived for v8-A (Falkor counts as a 2nd if it's an improved µArch).

IMHO QC was always going to favor a more Apple like fully custom hardware stack vs the semi custom approach they had from SD 835 -> SD 8 Gen 3.

Nuvia coming out of stealth must have been like a sign from the heavens to them - not that it wasn't still ridiculously over priced given how clearly little design they had done when acquired to have taken this long to come to market.

Also, is time to see how A530 is. Now I am thinking that is about to ditch the In Order Core unless they release an A630 variant being Out of Order, but based on the A530.
