This 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 sh…

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.

This is still an ARM C1-Ultra. Same one used in Mediatek dimensity 9500, which also got more than 4000 points in GB6 lab test. But actual results inside phone with smartphone cooling and wattage requirement became close to 3300. But perhaps the most important thing, Xiaomi is now able to make chip similar to Mediatek. They are the third largest Smartphone manufacturer by shipment volume. And they are still growing. T…

> This is bad news for Mediatek and Qualcomm.

And good news for everyone else.

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.

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-hom…

All 10 cores support the same extensions. It’s silly to implement an SoC any other way, and it’s been a decade since someone has last made that mistake.

And on iOS? (Also I'd recommend https://libredirect.manerakai.com/ )

it works on orion

It depends on the number of channels. The Xring O3 appears to have 4×24-bit channels, so 113.8 GB/s. The iPhone 17 Pro's memory bandwidth is ~76.8 GB/s. Seems fine?

If I recall correctly, Strix Halo gets about 450G/s. The M series processors get between 400 and 800G/s, and an actual NVIDIA card is like 5.5T/s. 113G/s is pretty slow for inference.

Strix Halo is 256 GB/s.

Apple's * Last Year* CPUs. We're literally about to get a new chip in 2-3 weeks from them.

Still better than what Qualcomm is offering?

I'm not sure that it matters. You can't put a Qualcomm chip in an iPhone and you can't put Apple Silicon in any other device. So there's no really straightforward way to compare them other than specs on paper, which we all know are theoretical until they get integrated.

I can install Firefox (and Chrome) extensions with the Orion Browser. It‘s developed by Kagi https://orionbrowser.com/ I also installed uBlock Origin on Orion, which works quite well on iOS
