Xiaomi YU7 uses Snapdragon 8 Gen 3 for performance and ecosystem synergy, balancing automotive certification challenges with consumer-grade chip cost.
When the YU7 achieved the impressive result of “240,000 orders in 18 hours,” it quickly became the hottest model in the auto industry, but controversy soon followed. For example, a ¥169 ($23.66) magnetic tissue box repeatedly trended online, as some netizens complained about the “excessive price.”
Lei Jun tried to calm the debate during a follow-up livestream by emphasizing that the tissue box is “automotive-grade.” Yet this only shifted the focus of criticism to the Qualcomm Snapdragon 8 Gen 3 chip inside the YU7.
Some skeptics asked, “The tissue box is automotive-grade, but the chip is consumer-grade?”
Though perhaps unfair, this criticism highlights some consumers’ dissatisfaction with Xiaomi’s choice to equip the YU7’s cockpit with the Snapdragon 8 Gen 3, a chip originally designed for smartphones.
But is “consumer-grade” truly a flaw? Lei Jun, who deeply understands consumer psychology, made this decision for the YU7 — was it really a mistake?
If you understand the auto industry better, you’ll know that using consumer-grade chips in vehicles isn’t uncommon.
Before Xiaomi, a major automaker that sells millions of cars per year had already widely applied consumer-grade chips in their 100,000-yuan ($14,000) models. Even struggling startup HiPhi once proposed replacing automotive-grade chips with non-automotive-grade ones.
Still, such choices are uncommon. What most people want to know is: why did Xiaomi insist on using the Snapdragon 8 Gen 3 despite public pressure?
Is it about cost savings, performance benefits, or something else?
Occasional Precedents
In China, automakers usually promote “automotive-grade” cockpit chips, with Qualcomm’s 8155 and 8295 being the typical examples.
But in reality, using mobile or desktop processors to power a vehicle’s cockpit is not unusual.
For example, Tesla’s refreshed Model 3 and Model Y both use AMD Ryzen processors to drive their cockpit systems. Tesla executive Grace Tao has said the chip delivers 10 TFLOPS of AI computing power, giving the system a smoothness that surpasses many laptops and rivals desktop computers.
According to teardown reports, Tesla’s current Model 3 and Model Y use an AMD-customized chip in their MCU 3.0 platform, replacing previous NVIDIA Tegra 3 and Intel Atom processors.
This AMD chip is essentially a PC-class x86 APU (with integrated Vega 11 GPU). Tesla also equips the system with a discrete Navi 23 GPU based on the RDNA 2 architecture, along with 8GB/16GB of RAM and a 256GB SSD, giving the system performance comparable to a desktop or small workstation.
Tests show that Tesla’s MCU 3.0 matches the gaming performance of consoles like the PlayStation 5 or Xbox Series X, enabling smooth play of AAA titles.
But not every automaker takes Tesla’s “top-down” approach.
Some 100,000-yuan ($14,000) cars use low-end mobile chips, such as MediaTek’s P35 or Qualcomm’s Snapdragon 665 — chips typically found in budget smartphones costing less than ¥1,000 ($140).
In fact, Xiaomi’s approach with the YU7 — using a high-end mobile chip — is rare. The only comparable case is HiPhi’s attempt to introduce the industrial-grade Qualcomm QCS8550 chip in 2023.
The QCS8550 is similar to the Snapdragon 8 Gen 2 in architecture and performance, and far more powerful than the automotive-grade Qualcomm 8155 and even the upcoming 8295 (with AI performance of 48 TOPS vs. 30 TOPS for the 8295). However, the QCS8550 is designed for industrial IoT and automation, not for automotive or consumer applications.
Both Xiaomi and HiPhi built a “automative-grade platform” around the chip to meet automotive standards.
This approach of building a certified platform around a non-automotive-grade chip is how Tesla and others also meet vehicle reliability standards.
Pros and Cons
So, why do automakers take this path? Let’s look at both the advantages and disadvantages.
Pro: Higher Performance for Less Cost
From a manufacturer’s perspective, the primary advantage is value for money.
The Snapdragon 8 Gen 3, though designed for smartphones, significantly outperforms the automotive-grade Qualcomm 8295P in computing power — and costs far less.
The Snapdragon 8 Gen 3, built on a 4nm process with eight cores and a top frequency of 3.3GHz, delivers 60 TOPS of AI performance, capable of running 10 billion-parameter AI models locally.
Xiaomi advertises faster boot times (1.35 seconds), faster OTA updates (15 minutes for a full car upgrade), and smoother app launches (cold start speeds up 9.5%).
In terms of graphics, the Snapdragon 8 Gen 3’s GPU delivers stronger performance. Xiaomi claims a 33% faster panoramic camera startup, 15.8% better app frame rates, and 13% improved responsiveness compared to the SU7 — which uses the automotive-grade Qualcomm 8295P.
Price-wise, the Snapdragon 8 Gen 3 reportedly costs $160–180 per thousand units (about ¥1,150–1,300), while the 8295P costs $280–320 (about ¥2,000–2,300) — nearly double the price.
Yet the Snapdragon 8 Gen 3 has a significantly newer architecture and performance closer to a flagship smartphone chip, while the 8295P is roughly equivalent to the Snapdragon 888 from 2020.
Benchmark results from AnTuTu place the Snapdragon 8 Gen 3 at 2.1–2.2 million points versus 800,000–850,000 for the Snapdragon 888 — a 2.5–2.7 times performance gap.
So purely from a cost-performance perspective, using the Snapdragon 8 Gen 3 makes sense.
Moreover, in certain cases, automakers can further enhance computing power by adopting a dual-chip or even multi-chip configuration. HiPhi even explored a dual-chip configuration using two QCS8550 chips for 96 TOPS of compute power.
But why hasn’t this approach become mainstream?
Con: Certification and Reliability Costs
The key issue is automotive certification.
The Qualcomm 8295P is certified to automotive-grade standards like AEC-Q100 and ISO 26262. The Snapdragon 8 Gen 3 is not.
According to Xiaomi’s official website, the YU7 further enhances the integration of its electronic and electrical architecture (EEA) by consolidating four domain controllers into a single “central brain,” moving one step closer to a centralized EEA structure.
Xiaomi states that the DCD cockpit domain controller motherboard, which houses the Snapdragon 8 Gen 3 chip, has passed the AEC-Q104 automotive-grade certification, and the “central brain” itself meets automotive-grade safety standards.
As mentioned earlier, in September 2023, HiPhi also adopted a similar approach, using what is called “module compliance” as a workaround to enable non-automotive-grade chips to meet automotive-grade requirements.
Unfortunately, HiPhi encountered operational difficulties in early 2024, and this solution was never fully implemented or validated in real-world production.
In addition to better stability, automotive-grade chips offer many other features specifically designed for in-vehicle scenarios. The most notable among these is their ability to support multiple screen outputs.
For example, the 8295P supports up to 8 concurrent 4K displays or a single 8K display, while the Snapdragon 8 Gen 3 is designed for a single high-refresh-rate screen — a reflection of their respective design priorities.
Additionally, consumer chips have much higher defect rates (500 PPM vs. 0–10 PPM for automotive chips). Given the critical role of the cockpit in modern vehicles, even occasional failures leading to black screens could severely damage the user experience.
Based on the approaches of Xiaomi and HiPhi, the main challenge of integrating non-automotive-grade chips into vehicles lies in designing a highly integrated module platform that can support the operation of high-performance chips while meeting stringent certification requirements.
This places higher demands on automakers’ fundamental design capabilities. Automakers also need extensive chip tuning experience to ensure that non-automotive-grade chips can operate reliably under extreme conditions.
On the other hand, although the chips themselves are cheaper, developing a new domain controller from scratch — as opposed to simply adopting the supplier’s standard kits or existing solutions — represents a significant additional cost.
Another possible reason is that most automakers lack a strong vision for the cockpit experience and thus have little desire for extreme performance. However, for companies like Xiaomi, differentiated cockpit experiences are a key selling point. The long update cycles and lagging performance of automotive-grade cockpit chips may not meet Xiaomi’s needs.
In the long term, this approach aligns with Xiaomi’s “human-car-home” ecosystem. Xiaomi has hinted that its self-developed “Surge” chips may eventually be used in vehicles. The Snapdragon 8 Gen 3 provides a testbed for that future transition.
Ecosystem Strategy
In multiple occasions such as earnings calls and online live streams, Xiaomi executives (including Lei Jun and Lu Weibing) have revealed that Xiaomi’s self-developed “Xuanjie” chip may be installed in vehicles in the future.
The use of the Snapdragon 8 Gen3 chip in the Xiaomi YU7 can be seen as an early trial, serving as a preliminary validation for the future deployment of the Xuanjie chip in cars.
Moreover, if Xiaomi leverages technological innovation to enable consumer-grade chips to meet automotive-grade stability tests, it means that Xiaomi won’t need to separately develop an automotive-grade version of the Xuanjie chip. Instead, the next-generation Xuanjie chip could be used across both consumer electronics and electric vehicles.
This is Xiaomi’s unique cost-saving strategy.
Xiaomi’s smart ecosystem also makes the application of consumer-grade chips in vehicles more feasible.
As mentioned earlier, mobile chips naturally have limitations in multi-screen output, but the multi-screen ecosystem in the Xiaomi YU7 is composed of independent Xiaomi tablets, each equipped with its own SoC. This reduces the demands on the cockpit chip’s multi-screen output capabilities.
If we also consider the “phone-to-car connectivity” scenario, when the chips in the car and the smartphone have similar performance and minimal kernel differences, application migration becomes much easier, reducing development costs.
Of course, HIMA products also feature a rich hardware ecosystem, but they follow a different path.
HIMA’s ecosystem integration does not rely on the chip itself. According to third-party sources, some of its vehicles use the automotive-grade Kirin 990A chip. The core of its ecosystem is the HarmonyOS, which has a unified underlying kernel capable of powering multiple device types.
From this perspective, compared to HiPhi’s concept proposed two years ago, Xiaomi YU7’s upgrade in its electrical/electronic architecture is far more comprehensive. Replacing the Qualcomm 8295P with the consumer-grade Snapdragon 8 Gen3 forms a complete logical and ecosystem loop.
Although it remains controversial today, over a longer time frame, adopting a powerful consumer-grade chip in the cockpit could become another memorable highlight of the YU7.
Of course, stability remains the key prerequisite. The YU7 only started deliveries on July 6, and it will take time to prove that its product strategy is flawless and can withstand harsh real-world conditions. Plus, given Xiaomi’s significant media exposure, even minor issues could quickly escalate into public relations crises.
Is the Xiaomi YU7 truly ready?
