Ever wondered how tech giants navigate around seemingly insurmountable roadblocks? When the U.S. tightened the screws with stringent sanctions, Huawei didn’t just roll over—it doubled down on innovation. Now, the company will equip the rising star Pura X with its newest Kirin application processor (AP). This achievement feels like a corporate David-and-Goliath story. In this post, we will look at how Huawei is moving forward with semiconductors. We will discuss the amazing features of the new Kirin AP. We will also see why this partnership could change the global mobile-chip market.
The U.S. Sanctions Background
Timeline of Restrictions on Huawei
2019: Huawei added to the U.S. “Entity List,” banning American firms from selling components without a license.
2020–2022: Expansions of restrictions, targeting semiconductor equipment—effectively cutting off TSMC’s advanced foundry services for Huawei.
2023–Present: Further curbs on third-party tools and software, forcing Huawei to localize its supply chain.
Impact on Huawei’s Chip Supply
Being shut out of TSMC’s 7 nm and 5 nm nodes would sink many companies. Huawei’s smartphone division lost its own Kirin chips in flagship devices, pivoting to Qualcomm—and yet, the in-house R&D stayed alive, cooking up next-gen AP designs in anticipation of a comeback.
What Is the Kirin Application Processor (AP)?
Evolution from Kirin 970 to Kirin 9000
Kirin 970 (2017): Introduced NPU for on-device AI.
Kirin 990 (2019): Added integrated 5G modem (NSA).
Kirin 9000 (2020): First 5 nm Huawei SoC, powering Mate 40 series.
Each iteration packed more CPU cores, GPU horsepower, and AI accelerators—pushing Huawei into the smartphone-SoC limelight https://consumer.huawei.com/en/phones/mate40-pro/specs/.
Technical Highlights of Kirin Architecture
Big.LITTLE CPU clusters for balanced performance and power efficiency.
Mali-series GPU optimized for Vulkan and OpenCL workloads.

5G RF front-end co-designed for lower latency and enhanced reception.
Who Is the Pura X Unicorn?
Startup Profile and Market Ambitions
Pura X is a Beijing-based startup developing augmented-reality wearables for enterprise training, interactive retail, and healthcare diagnostics. With a recent Series B funding round valuing it over $1 billion, Pura X earned its “unicorn” status—and now needs cutting-edge compute to power on-device AI and seamless connectivity.
Why Pura X Needs High-End APs
AR glasses demand:
More Read
Low-power AI inferencing (gesture recognition, environment mapping).
High-bandwidth 5G links for cloud data synchronization.
Thermal headroom in a compact form factor.
Off-the-shelf mobile chips can’t balance these needs as efficiently as a bespoke Kirin AP tailored to Pura X’s hardware.
Overcoming Sanctions: Huawei’s Workarounds
In-House Design and TSMC Alternatives
After losing access to TSMC’s cutting-edge nodes, Huawei accelerated its partnership with SMIC (Semiconductor Manufacturing International Corporation) and Hua Hong for mature nodes (28 nm, 14 nm). By redesigning circuits for these processes and leveraging advanced EUV replacements, Huawei squeezes peak performance from less-advanced fabs.
Open-Source and ARM Architecture Licensing
Huawei secured an ARM architecture license before sanctions tightened. By using ARMv9-compatible cores and leveraging the open-source OpenBMC firmware, Huawei maintains compatibility with the broader ARM ecosystem despite U.S. embargoes.
Domestic Chinese Foundry Partnerships
Collaborations with SMIC, YMTC, and Tsinghua Unigroup ensure a steady ramp of wafers. Huawei’s internal fab-integration team—once deemed overstaffed—now becomes critical, orchestrating node-shifting and yield-optimization.
Technical Deep Dive: The New Kirin AP for Pura X
CPU Core Configuration and Performance Targets
The bespoke Kirin AP features:
2× Cortex-X3 “super” cores at 3.0 GHz for peak single-thread tasks.
4× Cortex-A720 “performance” cores at 2.6 GHz.
4× Cortex-A520 “efficiency” cores at 1.8 GHz.
This arrangement targets a 40% uplift in integer performance over last-year’s Kirin 9000, while keeping battery drain modest.
GPU and AI Accelerator Innovations
Mali-G715 derivative with 14 clusters—delivering up to 1.2 TFLOPS of GPU compute.
New NPU architecture: “DaVinci 2.0”—boosting AI throughput to 30 TOPS, ideal for real-time AR inference on Pura X goggles.
5G Modem Integration and RF Front-End
A dual-mode 5G modem built in-house supports sub-6 GHz and mmWave. Advanced RF GaN power amplifiers co-developed with HiSilicon RF Labs yield up to 4 Gbit/s downlink in optimal conditions.
Power Efficiency and Thermal Design
Using a 14 nm node, the chip employs aggressive voltage island partitioning and activity-aware clock gating, keeping power draw under 6 W during sustained loads—critical for head-mounted Pura X devices.
Strategic Importance for Huawei
Reasserting Leadership in Mobile SoCs
By delivering a high-end AP under duress, Huawei signals to global partners that it remains a force in chip design—despite sanctions. This momentum may unlock new B2B deals and government contracts https://www.huawei.com/en/news/.
