Won't be enough outside of iPhones (which likely will stick to A series SoCs). I'm curious why Apple would bother with LPDDR if they add HBM, but seems like they plan on a hybrid of the two, but I'd think a unified memory pool would work better.
It probably would if the M1 is fine with 68GB/s. In the same config this will be ~135GB/s in a hypothetical M3, however no idea of a hypothetical M3X considering we don't know what type of RAM we'd get even in the supposed M1X.
? The M1 uses LPDDR4X without issue; still near-chart-topping in SPEC2017 & SPEC2006. Its GPU is also closest to a GTX 1650. What's your thinking that its LPDDR4X RAM has been a significant bottleneck to the M1's passive & light systems?
As Apple goes wider + more cores & especially bigger GPUs (!), LPDDR5X sounds like a straightforward upgrade.
//
Apple shares its SoC (and thus its memory controller) with a lot of systems, so ideally it'd only differentiate memory types once it's worthwhile; maybe the "M1X/M2X/M3X" desktop-class variants might splurge for HBM?
Apple just announced that their usual level of spending to prepay for components was about to go up by ~25%, so it's entirely possible that something new and expensive is in the offing.
It's interesting that you say it uses more power, since it actually uses less power than GDDR. Not sure about LPDDR5X, but then there's also the question of what they're both clocked at and how many stacks of HBM you're using.
v9 sounds absolutely boring. Nuvia CPU's and GAA transistors are much more exciting.
And my personal wish is to see better desktop modes and a RISC-V Android device. Two steps closer to a usable open-source and all-purpose pocket computer.
That doesn't change the initial expectation. Regardless of when, I was still disappointed they didn't do anything more ambitious. It's understandable, but now I have to pin my hopes on v10.

Nice, it'll be great for Apple's M3/M3X SoCs.darkswordsman17 - Thursday, July 29, 2021 - link

Titanium body for the iPhone might account for some of that.mode_13h - Monday, August 2, 2021 - link

ARM v.9 based CPUs, LPDDR5x, Potentially Adreno 700 series, Qualcomm Nuvia, next couple of years could get quiet interesting for Android usersWereweeb - Thursday, July 29, 2021 - link

Yeah, I was also disappointed with v9, but at least it makes SVE2 standard.dotjaz - Wednesday, August 11, 2021 - link
Disappointed for what? We knew for months it's v8.x+SVE2 with baseline features re-aligned.mode_13h - Thursday, August 12, 2021 - link

No MT/s?Freakie - Thursday, July 29, 2021 - link
Don't you mean MHz? 👀...*hides from Dr. Cutress*...

Do you mean MT/s instead of Mb/s!
