Huawei reserves the Kirin 9050 Pro for its top Mate 90 models

The first sentence of Huawei's release identifies the LogicFolding Tau Chip as the Kirin 9050 Pro ^[1]. The spec section then puts the Tau chip "at the heart" of the Pro Max ^[2]. It names the 9050 Pro specifically for the Pro Max Premium Edition and the RS Ultimate Design ^[3]. The release does not say whether the Kirin 9035 or the Kirin 9030 is built with LogicFolding ^[4]. By the release's own definition of Tau, the slogan is confirmed for the top of the range and unconfirmed for everything below it.

Huawei says LogicFolding cuts critical-path latency and reaches 5 million signal transmission bonds and 125 TB/s of inter-die bandwidth ^[9]. Inter-die bandwidth only matters when a chip is split across more than one die. So the headline figures measure how the dies are connected to each other. The tooling explains the design. Yu said China's advanced chipmaking still relies on DUV lithography, and that Chinese manufacturers are still working towards EUV, which he called "valuable" ^[10]. According to the Economic Times, US restrictions have limited Huawei's access to cutting-edge chipmaking tools and forced it to find other ways to raise processor performance ^[11]. I think bonding several dies together is sound engineering under that limit.

Yu's own description of supply argues against a lineup with the same chip in every model. "Advanced semiconductor capacity remains very limited in China, and Huawei's Ascend AI chips also draw on that same capacity," Yu said ^[5]. "The capacity for smartphone chips remains tight, even though rising smartphone prices have curbed shipment volumes (for handsets)," he said ^[6]. In my view, putting the scarcest part in the highest-priced editions and older-numbered parts lower down is the right call for a vendor in that position.

The performance claims are 31% for the 9050 Pro, 20% for the 9035 and 27% for the 9030 ^[3][4]. Only the top-end figure has a reported baseline: the previous flagship generation, according to the Economic Times ^[8]. The standard model gains more than the Pro. That only makes sense if each chip is measured against a different predecessor, so the three numbers cannot be ranked against each other. For 31% to hold on another workload, Huawei's test would have to resemble that workload.

The Pro Max price rise is 25% on the predecessor's launch price of 7,999 yuan ^[17][18]. Yu said rising memory prices had added an average of $200 to the cost of each handset and were squeezing margins ^[14]. "We have to increase prices as well, yet at a slower pace," Yu said ^[15].
