ARM is merely an IP portfolio licensing company. They don't really design or build anything. And everyone uses TSMC (who uses ASML). The primary design is still being done by Xiaomi, that's the most unique part of this build.
Stop downplaying how big of an achievement this is.
- free652 23d agoReally?! Did you read the announcement? C1 ultra cores are designed by ARM. >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). >https://www.arm.com/products/silicon-ip-cpu/c1-ultra https://www.arm.com/products/silicon-ip-cpu/c1-ultra
- f1shy 23d agoARM does the design. What are u talking about?
- refulgentis 23d agoYou are misunderstanding, and, they are not downplaying. A revision or other reply would benefit from explaining how their value chain x location correspondence is wrong - perhaps missing a step? Though, in anticipation of a revision, I wonder if its simple as you thought the cores were custom-designed by Xiaomi instead of standard ARM.

- tverbeure 23d agoAnd how did that IP portfolio come into existence? Did it suddenly materialize out of thin air or… did ARM engineers design it? I’m going to give you the benefit of the doubt: in your mothertongue, the meaning of “design” is not as broad as in English?
- menaerus 23d agoHow about Apple M series ARM chip designs? From what I have seen only resemblance with ARM is the ISA.
- tverbeure 23d agoWhat about it? Apple has an architectural license which allows them to design their own CPUs with ARM ISA. Most companies that use ARM CPUs don’t.
- menaerus 23d agoYour initial response made it sound as if Xiaomi did nothing wrt chip design and all the hail goes to "ARM engineers" which is simply not true. Had that been true we would have dozens of chip designers which we don't.
- adolph 23d agoBelow is some additional detail about the processor. Like the parent comment notes, ARM licenses IP of an ISA or core designs (see ARM C1-Ultra cores [0]), licensees like Qualcomm then make specific SoC for different use-cases. Xiaomi has made the XRING 03 boast a larger die size than the XRING 01, measuring 133mm² compared to its predecessor’s 109mm² dimensions This change was deemed necessary as the flagship SoC features 16MB of SLC cache, not to mention a new “6 + 4” CPU cluster that comprises two ARM C1-Ultra cores running at 4.35GHz, four C1-Premium cores operating at 3.68GHz and lastly, four C1-Pro cores running at 3.15GHz.

- burnte 23d agoThey license the IP that they design. They design complete chips you can buy and go right to tape out with no changes if you want.
