SMIC’s Kirin 9030 Shows China’s Chip Progress, But TSMC Still Holds a Major Lead
China’s semiconductor industry has been forced to innovate under pressure. With SMIC unable to access advanced EUV lithography equipment, the company has had to squeeze more performance and density out of older DUV tools. The result is Huawei’s Kirin 9030, the chipset powering the Mate 80 flagship series, and it offers one of the clearest looks yet at how far China’s chipmaking ambitions have come.
At first glance, the Kirin 9030 appears surprisingly competitive. A close technical examination of the chip shows that SMIC has managed to achieve an impressively tight metal pitch on its 7nm N+3 process. The smallest measured metal pitch reportedly comes in at 32.5nm, which is around 10 percent tighter than Intel’s 18A process used for Panther Lake CPUs, measured at 36nm.
That is a notable achievement, especially because Intel 18A is considered a far more advanced manufacturing node on paper. Even more interesting, SMIC’s 7nm N+3 process also appears to offer a tighter metal pitch than TSMC’s N6, which has been measured at around 40nm in chips such as MediaTek’s Helio G99. TSMC’s N6 uses EUV technology, while SMIC is still relying on DUV-based techniques.
This makes the Kirin 9030 an important milestone. It shows that SMIC can continue improving density without access to the most advanced lithography machines. Through techniques such as multi-patterning, design technology co-optimization, and complex integration methods, the company has managed to push its existing tools further than many expected.
However, chip manufacturing is not judged by density alone.
While SMIC can claim progress in area scaling, the Kirin 9030 also reveals the compromises required to get there. Density is only one part of the equation. Power efficiency, clock speed, transistor performance, thermal behavior, manufacturing yield, and overall chip design all play critical roles in determining whether a process node is truly competitive.
This is where the gap between SMIC and leading foundries such as TSMC, Samsung, and Intel becomes much clearer.
The Kirin 9030’s prime CPU core reportedly delivers performance and efficiency comparable to Arm’s Cortex-X2, a high-performance core design introduced in 2021. That comparison is important because the Cortex-X2 is now several generations old. Modern flagship chips from Apple, Qualcomm, and MediaTek have moved well beyond that level in both performance and power efficiency.
One of the most striking comparisons involves Apple’s efficiency cores. According to the analysis, Apple’s efficiency cores can deliver roughly 20 percent higher integer performance than the Kirin 9030’s prime core while consuming only about 1 watt of power. By comparison, Huawei’s prime core reportedly draws around 4.5 watts.
That difference highlights the real challenge facing SMIC. Even if the company can produce a dense chip layout, it still struggles to match the voltage-frequency characteristics and power efficiency of chips manufactured on more advanced TSMC nodes. In practical terms, that means the Kirin 9030 may need more power to reach performance levels that competitors can achieve more efficiently.
This matters a great deal in smartphones. A mobile processor must balance speed, heat, battery life, and sustained performance. A chip that draws too much power can throttle sooner, run hotter, and reduce battery endurance. For flagship devices, efficiency is just as important as raw speed.
The comparison with TSMC’s N6 process also needs context. While SMIC’s 7nm N+3 process may look similar or even better in certain density measurements, TSMC N6 is not a cutting-edge node anymore. It is an older process in TSMC’s lineup, while the company has already moved through 5nm, 4nm, and 3nm production, with 2nm-class chips expected to raise the performance and efficiency ceiling even further.
That means SMIC is improving, but the global leaders are not standing still.
TSMC’s more advanced nodes give companies such as Apple and Qualcomm access to much larger transistor budgets, better efficiency, and stronger performance headroom. As 2nm chips enter the market, that advantage is expected to grow. More advanced nodes allow designers to pack in more logic, more cache, better graphics hardware, and improved AI accelerators while keeping power consumption under control.
SMIC’s use of multi-patterning also brings complexity. Without EUV, creating extremely small features requires additional lithography steps. This can increase manufacturing difficulty, raise costs, reduce throughput, and create yield challenges. In other words, SMIC may be able to build dense chips, but doing so efficiently and at scale remains a separate problem.
The Kirin 9030 is therefore both impressive and limited. It proves that China’s chip industry can make meaningful progress despite restrictions on advanced manufacturing equipment. It also shows that Huawei and SMIC are finding creative ways to keep flagship smartphone hardware alive. For China’s domestic technology ecosystem, that is a significant achievement.
At the same time, the chip does not prove that SMIC has caught up with TSMC, Intel, or Samsung. The process may look strong in selected density metrics, but it still trails in power efficiency, performance, and overall manufacturing maturity. The gap is smaller in some areas than many expected, but it remains substantial.
One possible path forward for Huawei could be advanced packaging. Huawei’s LogicFolding packaging approach may help improve competitiveness by using stacking techniques to recover density, shorten signal paths, and potentially boost performance. Advanced packaging has become increasingly important across the semiconductor industry, especially as traditional scaling becomes harder and more expensive.
If Huawei can combine denser packaging with continued improvements in SMIC’s manufacturing process, future Kirin chips may become more competitive. But for now, the Kirin 9030 should be seen as a clever engineering achievement rather than proof of parity with the world’s leading chipmakers.
The bigger picture is clear: SMIC is progressing under difficult conditions, and the Kirin 9030 demonstrates real innovation. But catching up to TSMC, Samsung, and Intel will require more than tighter metal pitch measurements. It will require better efficiency, stronger transistor performance, higher yields, advanced packaging, and eventually access to more capable manufacturing technologies.
For now, Huawei’s Kirin 9030 is a symbol of China’s determination in semiconductors. It is not yet a world-beating mobile chip, but it shows that the race is far from over.
