Huawei Technologies today showcased its chipset for a new high-end smartphone, pressing ahead with plans to launch its Mate 30 range.
This is despite uncertainty about whether the new phones will be able to run Google's Android operating system and apps.
The Chinese tech giant bills the Kirin 990 chipset as the first all-in-one 5G system on a chip.
It describes it as superior to alternatives from Qualcomm and Samsung that, it says, graft 5G modems on to 4G chips.
The launch at the IFA consumer electronics fair in Berlin of the Kirin 990, made using the latest 7 nanometre production process, is part of a carefully sequenced buildup to the September 19 international launch of the Mate 30 in Munich.
Yet, say Huawei sources, it is still not known whether the Mate 30 will be able to run services from Alphabet's Google after the blacklisting of the Chinese company by the US administration in May.
That ban sliced 5 percentage points off Huawei's market share in Europe.
The world's second biggest smartphone maker is looking to reclaim ground as the spread of ultra-fast 5G networks prompts an upgrade cycle among consumers who have been holding on to phones for longer.
Consumers will need new handsets to take advantage of the ultrafast download speeds promised by 5G.
The services in doubt include pre-installing the Google Play store and a suite of popular apps such as Google Maps that buyers would expect to be available from the moment they turn on their new phone and synch it with their profile.
Huawei's fallback option would be to run the devices on its home-grown Harmony operating system, although company officials and analysts say it is not yet ready for prime time.
The Kirin 990 packs more than 10 billion transistors and can support downlink speeds of up to 2.3 gigabits per second.
It has an adaptive receiver that enables it to switch between 4G and 5G where coverage of the faster technology is weak.
And, to save energy, it has a 'big core' to handle powerful computing tasks with the support of artificial intelligence, and a 'tiny core' for less demanding operation.
Huawei plans only to use the Kirin 990 in its own devices, meaning it lacks the marketing opportunities enjoyed by Qualcomm, whose chips already power the Samsung 5G phones, such as the Galaxy 10, already on the market.
Apple's recent settlement of a patent dispute with Qualcomm, and Intel's exit from the smartphone modem business also reflect the US chipmaker's muscle in a global market that is increasingly fragmenting due to the US-China trade tension.
