Xiaomi successfully “tapes out” China’s first 3nm smartphone chip
Oct 21, 2024
Xiaomi has been rumored to be working on its very own smartphone chip for a while now. Looks like the company has now reached an important milestone.

A report by Chinese media MyDrivers suggests that Xiami has successfully “taped out” the country’s first 3nm smartphone SoC.

The announcement came from the Chief Economist of the Beijing Municipal Bureau of Economy and Information Technology on BRTV, a government-owned television network in China. Below is the announcement video of the same, in Chinese of course, posted by an X user.

Xiaomi’s own smartphone SoC?

The report doesn’t provide details about the CPU or GPU and only mentions that it is a 3nm chip. It also doesn’t specify whether Xiaomi is using TSMC, Samsung, or another node for production.

However, the “tape-out” process in silicon design means the chip has reached the final stage before it’s sent to the manufacturing facility for production. In other words, Xiaomi has successfully completed the design phase and the chip is now ready for fabrication.


That said, this doesn’t mean the SoC is ready for mass production or smartphone use yet. Xiaomi will still need to test the chip once it’s fabricated by a manufacturer like TSMC or Samsung. Also, if the initial yield (the percentage of working chips) is low, they may need to tweak the manufacturing process or the chip design to improve it.

In case you didn’t know, Xiaomi has already released a smartphone with its own SoC. The Mi 5C, launched in 2017, featured Xiaomi’s Pengpai (or Pinecone) S1 chip, a 28nm, 8-core processor with a big-little architecture and a maximum clock speed of 2.2GHz.

While Xiaomi hasn’t launched another smartphone SoC since then, it has been developing chips for charging, battery management, and image signal processing in its Surge G, P, and C series. For instance, the Xiaomi 14 Ultra uses the Surge P2 and G1 chips to improve charging efficiency and extend battery life.

So, chip production certianly isn’t an unfamiliar territory for Xiaomi. It remains to be seen if the company can successfully develop and launch its own smartphone SoC (again), and how it will stack up in terms of performance.

walauweh!

Yaoyao

Huashit

murica shouting sanction sanction

Didn't know got previous chip, how was the pinecone? Can rival sd or mediatek midrange?

fooyuh! i didn't even know that xiaomi was designing their own chips.

Gonna be buggy just like their software

But.. ipong already using 3nm chip.

Why need to copy

So Huawei kalah?

use own chip so that can spy properly. otherwise israel put a bomb there also dont know.

we build for ghaina

in other news, samseng want to use inferior exynos chip because qualcomm soc is too expensive.

Looks like PRC hybrid capitalism innovation can rival USA free market capitalism.

now now

should rename to ussmc instead.

once remember someone comment huawei will only spend time talking about their chip if it is self designed, but other china phone company will spend 30 min talking about chip that they dont even design.

hualawei last time kena use sd chip, during product promo only use 5 sec say to talk what chip is that. kek

btw, since last year alot china brand already shift to use their own screen supplier, own glass supplier, own camera sensor supplier and so on.

now most flagship use BOE/TCL screen, use their own glass and u hardly hear any gorilla glass, use their own OV camera sensor, and use their own SiC battery.

next year on wards, most flagship will habe more than 6000mah battery already

If Epal can, so can they.

But don;t buy their cars until at least 3rd version.

If Xiaomi's 3nm tape-out uses TSMC or Samsung fab, it's no difference because if kena US sanction, the supply to Xiaomi will also be halted.

So did you buy the Huawei Pura 70 Ultra?

Do you love the fact that an almost RM7000 phone cannot record video in 8K?

The photos look amazing though. But who are you kidding, woomiao? The Kirin processor is slower than a RM1500 Poco F6 by a wide margin.
