Discussion Qualcomm Snapdragon Thread

Rumor is that this could be for next year (Hawi).

Oh no, it gives me Crashtor Lake flashbacks... best of AMD is boosting to 5.7 Ghz at 170W. How they can boost to 6.1 Ghz?

When those are their best IPC increases since 2020, yes it's time to talk stagnation.

Also, Qualcomm doesn't need to match IPC exactly. Their cores are small, built for clocks and they're already very efficient (just a smidge less than Apple's last year, probably the same thing this year). Closing the IPC gap some is good (and they empirically seem to be doing that) but for example ARM's stock big cores have better IPC and they're less efficient and less performant. IPC isn't the be all and end all.

The cores are already extremely wide. And it's very strange to expect +20-25% IPC, as some people here dream of.

Raptor Lake was on 10nm+++, this will be made on some TSMC 2nm process. The voltage needed to reach this frequency will be much lower. 5 GHz (briefly) phone processors are coming. Don't be mad, it's just the way things work out.

I don't dream of 20+% YoY, I'm just pointing out that a sub 5% average over 5 years is stagnation and that Oryon's 10+% bump empirically means QC is closing the gap. A couple more years like those and they would overtake Apple's IPC. I'm not saying that will happen, nor am I saying it needs to happen for that matter, just that the Nuvia team is doing great work improving a core that was already top notch last year.

Well... AMD is using 4nm and the best version of it, so, in 2nm don't expect miracles.

So? Zen isn't really relevant to what can be done for a phone chip.
QC need a few hundred megahertz more but because it crosses some imaginary threshold it becomes a bad idea. A balanced design will push frequency as process allows.

Apple is done... ST wise got caugh up and MT wise got defeated. In the same month...

No one is switching from iPhone over this. Or Mac. If you think that then where are all the people who switched from Android to iPhone because of Apple's CPU performance? Or switched from Windows to Mac solely for CPU performance? That didn't happen, and for the same reason it won't happen in reverse.

Intel and AMD are the ones that should be worried, that means Qualcomm PCs will not be just caught up to x86 PCs performance wise like last year but beating them. Maybe Qualcomm will be able to grab a meaningful share of Windows laptops if they can match x86 performance under emulation and beat it on native. The odds are still stacked against them because people worry about compatibility & unfamiliarity, and CPU performance/efficiency is just one dimension they consider. But they are in a better position now, and Intel/AMD better pay attention.

no software, perf doesn't matter there.

Irrelevant. They need better product choices first.

Indeed, if people switches is not from X86 Windows to ARM Windows, just jump to Apple.

And in some countries people wants to jump off Apple, but sees the other side (Google's screwups) and they forget on it.
Damn Google.

Only in China they can jump off somewhere else.

Both 8E Gen 5 and D9500 are rumored to support up to LPDDR5x-10667. BiliBili now has leaks saying 8E Gen 5 might demo performance figures using LPDDR5x-12700 from Samsung....

Even Apple has upped the GPU figures with around 3000 scores in SNL; 8E Gen 5 and D9500 are rumored to hit 3200 scores, go figures.

 

[Doug S]

I was kind of surprised that Apple stepped all the way up to 9600 with A19P, but I guess that speed is pretty much mainstream now and 10667 and 12800 are the lower volume niche bins.

Makes me wonder if Apple might end up with something faster than 9600 for M5 Max.
