Huawei’s next smartphone chip taps new scaling law for performance boost: paper
The chip is set to power the Mate handset and will use Huawei’s Tau Scaling Law framework, which drastically shortens distance that signals travel in circuit
Huawei Technologies’ coming smartphone processor is on track for a performance boost, without the need for more advanced processing nodes or lithography technology, according to new production data unveiled by the firm.
An improvement in a single technological generation, achieved with the same process node for the two Kirin chips, would have previously required three years of traditional geometric scaling by shrinking the transistor size, according to the paper updated last Friday.
Operating at 25 degrees Celsius and 0.9V, the Kirin 2026 also reduced power consumption by 41 per cent to achieve the same level of performance as the Kirin9030 Pro baseline, with a 5.6 per cent decrease in power density.
The double-layer folding architecture has drastically shortened the distance that signals travel by cutting wire length down by 30 per cent, reducing clock-buffer count by over 50 per cent and clock skew by 25 per cent, the report said.
The research, published on ChinaXiv, a publication platform for scientific papers that have yet to be peer reviewed, gave the industry a glimpse of the actual engineering details and production data after He presented the theoretical framework of the Tau Scaling Law in late May.
