Just a couple of days ago, Huawei rolled out the Kirin 990 SoC. Designed by Huawei's HiSilicon unit and manufactured by TSMC using its 7nm+ EUV process, each chip contains 10.3 billion transistors and has an integrated 5G modem chip. The component will be powering the new Mate 30 line and the delay in releasing the foldable Mate X has allowed Huawei to stuff that device with its new chipset as well. Originally, the Kirin 980 SoC was designed into the niche device.
The Kirin 990 has eight CPU cores; four are powerful Cortex-A76 cores (with two running at a clock speed of 2.86GHz and the other two at 2.34GHz). And there are four Cortex-A55 cores with a clock speed of 1.9GHz for general housekeeping. The one question that many are asking is why Huawei didn't include ARM's latest and greatest Cortex-A77 core inside the Kirin 990. And when that question was asked of Richard Yu, CEO of Huawei's consumer group, he gave some interesting responses according to GizChina. And no, it has nothing to do with the U.S. supply chain ban.
The Huawei executive said that since the performance of the Kirin 990 is "beyond the user's needs," trading additional power in exchange for a shorter battery life is not worth it according to Yu. Even though ARM says that the Cortex-A77 provides a 20% boost in performance with no additional power consumption, Huawei's testing contradicts ARM's claims.

MediaTek Dimensity 1000 octa-core SoC promises 5G for the masses when it launches in 2020
The 5G SoC will support 90 Hz QHD displays, up to 16 GB of quad-channel LPDDR4x RAM, Wi-Fi 6, Bluetooth 5.1, hexa-core AI processor, download/upload speeds of up to 4.7/2.5 Gbps, and more with the promise of faster performance than the current Qualcomm Snapdragon 855.
While a handful of 5G smartphones are already available today, they are all prohibitively expensive. The Samsung Galaxy S10 5G, for example, currently retails for $1300 unlocked. MediaTek hopes to be the catalyst for 5G adoption next year by launching an all-in-one SoC solution that integrates an octa-core CPU, octa-core Mali-G77 MC9 GPU, hexa-core AI APU, and a 5G modem for more affordable smartphones.
Called the Dimensity 1000, the SoC will be the first in a series of SoCs with integrated support for 2G, 3G, 4G, and sub-6 GHz 5G networks. MediaTek is also claiming it to be the world's first SoC to support 5G dual-SIM for better worldwide appeal and versatility. While single-SIM smartphones are still prevalent in the U.S., most smartphones overseas tend to carry two SIM slots.
MediaTek's presentation shows that the SoC will support AOMedia Video 1 (AV1) hardware decoding at up to 4K60:
In addition to hardware video encoding and decoding at 4K 60FPS, the MediaTek Dimensity 1000 is the world's 1st mobile SoC with AV1 format support.

Huawei has sued the Federal Communications Commission over the agency's order that bans Huawei equipment in certain government-funded telecom projects.
[...] The FCC voted unanimously on November 22 to ban Huawei and ZTE equipment in projects paid for by the commission's Universal Service Fund (USF). The order will affect many small telecom providers that rely on the companies' network gear.
[...] "The US government has never presented real evidence to show that Huawei is a national security threat," Song said. "That's because this evidence does not exist. When pushed for facts, they respond that 'disclosing evidence might also undermine US national security.' This is complete nonsense."
[...] "We've built networks in places where other vendors would not go. They were too remote, or the terrain was difficult, or there just wasn't a big enough population," he said. "In the US, we sell equipment to 40 small wireless and wireline operators. They connect schools, hospitals, farms, homes, community colleges, and emergency services."
Hoftstra University law professor Julian Ku said that "even a small [Huawei] victory in the case, one that makes the FCC go and start the process over again, would be a huge victory for them," according to The New York Times. But it may be a difficult case for Huawei to win because US courts usually give federal agencies "a tremendous amount of deference," Ku said.
