Leaked details reveal Huawei's mid-range Kirin 8030 will use SMIC's 7nm N+2 node with improved clock speeds, targeting Snapdragon 888-level performance despite being years behind cutting-edge manufacturing.
Huawei's upcoming Kirin 8030 chipset has leaked, revealing modest performance improvements built on aging semiconductor technology. The mid-range processor, expected to power future Huawei nova and Enjoy series smartphones, shows clock speed gains over its predecessor but remains constrained by SMIC's 7nm manufacturing process.
Clock Speed Improvements on Legacy Node
The Kirin 8030 will feature Huawei's in-house Taishan CPU cores with a configuration of 1x super large core at 2.8-3.0GHz, 3x medium cores at 2.4-2.6GHz, and 4x small cores at 1.8-2.0GHz. This represents a significant clock speed increase compared to the Kirin 8020's 1x super large at 2.28GHz, 3x medium at 2.05GHz, and 4x small cores at just 1.3GHz.
Despite these improvements, the chipset is described as delivering single-core performance similar to the Snapdragon 888 and higher multi-core performance. This comparison is particularly interesting given that the Snapdragon 888 was manufactured on a 5nm process node using Samsung's fabrication technology in late 2020, while the Kirin 8030 will use SMIC's 7nm N+2 node.
Manufacturing Constraints and Industry Context
The use of SMIC's N+2 node highlights the significant challenges Huawei faces due to US sanctions restricting access to advanced semiconductor manufacturing equipment. While 7nm was considered cutting-edge in 2018-2019, the industry has since moved to 5nm, 4nm, and even 3nm processes.
SMIC's achievement in developing this node without EUV (Extreme Ultraviolet) lithography equipment is noteworthy. The transition from DUV (Deep Ultraviolet) to EUV began around the 7nm node for Samsung and TSMC, but required access to ASML's EUV machines - equipment that SMIC cannot obtain due to export restrictions.
Graphics and Gaming Performance
The Kirin 8030 is expected to use Huawei's Maleoon GPU, targeting 100-120fps in select games. While specific game titles weren't mentioned in the leak, this performance target suggests the chipset will handle popular mobile games at high frame rates, though likely with some thermal and power limitations inherent to the older manufacturing process.
Advanced Features Despite Process Limitations
Interestingly, the Kirin 8030 will incorporate several advanced features that help offset the manufacturing disadvantages:
- Barong 5G modem with support for both sub-6GHz and mmWave frequencies
- Leonardo da Vinci NPU delivering performance closer to the Snapdragon 8 Gen 2 than the 888
- New architecture design that benefits from Huawei's accumulated expertise
The NPU performance claim is particularly notable, as it suggests Huawei has made significant advances in AI processing efficiency that can partially compensate for the process node disadvantage.
Industry Timeline and Future Prospects
SMIC announced volume production of its N+3 (5nm) node at the end of last year, achieved without EUV equipment. This suggests Huawei's flagship Kirin 9030, built on the N+3 node, represents the company's best current effort at competitive performance.
The Kirin 8030's positioning as a mid-range chipset makes its specifications more understandable - it needs to balance cost, power efficiency, and performance for devices in the nova and Enjoy series price brackets. The clock speed improvements and feature set appear reasonable for this market segment, even if the underlying process technology lags significantly behind competitors using TSMC or Samsung's most advanced nodes.
The leak provides insight into how Huawei continues to innovate within severe technological constraints, pushing the limits of available manufacturing processes while developing new architectural solutions to maintain competitiveness in the smartphone market.
