Precisely. AMD have also clearly stated that they don't mind making ARM processors for clients if they ask for it. At the end of the day, AMD is happy and willing to make semi-custom parts for anyone who asks, regardless if it's x86 or ARM. If someone reaches out to them to ask for a custom ARM core, they'd do it.
How close is X4?
We won't even see it in action till SD8 Gen 3 next year, and given IPC can change based on cache configuration we can't take ARM numbers as a given without knowing Qualcomm's choices there.
Interesting point. How big will the IPC gain be from a bigger cache? I really wonder sometimes what would happen if ARM'S cores aren't starved like they are.
Can't be sure, ARM usually give only one set of figures which I would presume to be the ideal configuration.
I don't see the attachment... Did it unlink?
Apple Silicon team lost CPU talent but they have been hiring a lot of GPU engineers from ex Nvidia. Their focus seems to turned to GPU and AI/NPU.
ARM should partner with the Raspberry Pi foundation and put out a demo SBC each generation that contains their latest and greatest. Quite often their licensees drop the ball when it comes to performance and efficiency, ESPECIALLY QUALCOMM.
Hence why I said it would take ARM three generations to catch up to Apple, assuming Apple doesn't improve their P cores all too much. It would amount to ~15% IPC gains per year.
Does anyone know the die dizes/transistor counts of the A16/A17/X3/X4 cores?
might want to prod someone who $ubscribed to Techinsights
SD 8 Gen 2 is from last year, 8 Gen 3 will be released less than a month, that will be fair comparison with A16.
All AMD Zen chips, Stoney Ridge, Bristol Ridge, and Carrizo have ARM Cortex A5 "TrustZone" cores present. It varies in location but is always there.
A17 you mean?
No chance. The gap is too huge to be closed by a 15% IPC gain.
Yes A17,
RPi5 also uses a Broadcom SoC with their homegrown VideoCore GPU that basically no one else actually uses but RPi at this point.
What this really means is: if someone wanted Raspberry Pi SBCs with something like an SoC with X4 cores on it, Broadcom would first have to agree to produce and provide those SoCs at a price that made sense. And in turn the Pi Foundation would have to agree to lay out the cash for a run of boards with those SBCs even if the margins were thin-to-none. Those stars haven't lined up yet.
True.

Lol no wonder they have been so supportive of the Panfrost driver recently! 😅Funny you should mention that:
Arm Product Security Center
Arm is committed to upholding the highest standards of security across its products and the wider Arm ecosystem. To support its partners and the broader community, Arm publishes three types of security-related documentation, Security Bulletins, Security Updates, and Security Articles.
With 0% IPC gain that’s what you’d get, about 2500. But the IPC gain on Geekbench should be about 9-12% last I checked. The gains on GB usually outweigh their spec gains with Arm or did before. At any rate they could absolutely close the gap to like ~ 200 points with a similar clockspeed as Apple.
