alt Hacker NewsThis smells somewhat legitimate and somewhat BS. The architecture itself looks impressive — TSMC 3nm, a 4+ GHz prime core, tons of cache, and a very wide execution engine. And the claimed Geekbench numbers — around *3,945 single-core and 15,221 multi-core* — are especially impressive, if not a little suspicious.
But it’s sorta like, let’s throw everything against the wall and get the biggest number we can. Do they show sustained performance over ten minutes? What’s the power draw when it’s doing 15K? What happens when you put it in an actual phone?
This was done in a cold room. It seems more like a proof of concept for what they could do than something that could actually ship in a phone and sustain those numbers.

It will be interesting to find out the details. From the block diagram, the core only issues 10 instructions per cycle, so not especially wide. Maybe the performance will be worse once in a real phone in real thermal conditions, but if that's true, it could make for a very interesting laptop or desktop chip. Time will tell.
Doesn’t matter. Details don’t matter. Look at the top comment thread: just politics and no discussion of the tech.
It is just the same as MediaTek Dimensity 9500. They managed 4000+ point in lab, but real world it was much closer to 3300.
It is still not a bad results though. And we are about to see MediaTek Dimensity 9600 based on ARM C2-Ultra.

From what I recall reading, the impressive performance of Apple mobile CPUs is partly attributable to throwing more silicon area at the problem while not being as cost sensitive (no need to share margin with SoC vendor)
Were I to guess
> The biggest cores on the the Xring O3 are the C1-Ultra. C1-Ultra really powerful cores. They support SME2 (Scalable Matrix Extension 2) for matrix/AI acceleration, SVE2 for data parallelism (SIMD).
This is where the magic is happening (I believe). They have these ultra cores with additional extensions which they are pinning the benchmarks to.
Realistically, that sort of thing isn't useful as non-homogeneous architectures really suck for an application or OS to deal with.
