Kirin 990 5G is a 64-bit high-performance mobile ARM LTE SoC designed by HiSilicon, introduced on September 6th 2019, first appearing in the Huawei Mate 30 Pro. Fabricated on TSMC's enhanced 7nm+ EUV process, the 990 5G incorporates two high frequency Cortex-A76 cores operating at 2.86 GHz along with two medium frequency Cortex-A76 cores operating at 2.36 GHz along with four Cortex-A55 cores operating at up to 1.95 GHz.
The 5G model of the Kirin 990 is one of the first SoC that fully integrates a 5G modem (Balong 5000) in the same silicon as the CPU and the GPU. The Kirin 990 5G includes a limited version of the Balong 5000 modem that supports Sub-6-GHz frequency but no mmWave (commonly used in the USA).
There will be a Kirin 990 4G Version, including the Balong 765 with 4G LTE (3GPP Rel. 14) in the SoC.
The Kirin 990 5G supports up to 2.3 Gbps download and up to 1.25 Gbps upload speed and supports LPDDR4X-4266 memory.

Overview
Introduced at the 2019 IFA, the Kirin 990 uses the same ARM cortex (Cortex A76 + Cortex A55) versions as its predecessor, the Kirin 980, but the clock frequencies have been increased thanks to TSMC's more advanced manufacturing method, the 7nm+ EUV node: The 990 features two high-performance big Cortex-A76 core operating at 2.86 GHz, 2 medium-performance big Cortex-A76 operating at 2.36 GHz, and four little Cortex-A55 cores operating at 1.95 GHz. Compared to the 980, the 990 5G features between 10% - 35% power efficiency due to the 2nd generation of 7nm process node. The 990 ballooned to over 50% more transistors from 6.9 billion in the 980 to 10.3 billion. The 990 incorporates an in-house developed DaVinci NPU dual-neural processor designed for AI acceleration.

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory. The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC. Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies. Note: All units are in kibibytes and mebibytes. |
