Reviews of Huawei Mate 9

Review of Huawei Mate 9

                             Performances and responsiveness are important for any phone, but the essential for a flagship like the Mate 9. Making its debut inside the Mate 9’s aluminum chassis is HiSilicon’s new Kirin 960 SoC. The four ARM Cortex-A72 CPUs in the Mate 8’s Kirin 950 have been replaced by four of ARM’s latest Cortex-A73 CPUs. And The plus-one change in model number is deceptive, however, because there are some significant differences between the two cores. The A73 actually belongs to a different processor family, with its roots going back to the A17 rather than branching out from the A15/A57/A72 family tree. One of the obvious differences between the two different micro architectures is a reduction in decoder width: The A72 has a 3-wide decoder while the A73 is 2-wide. Despite what appears to be a reduction in capability on papers, ARM claims the A73 still offers better performances and efficiencies  such relative to A72 on the same process and frequency. Four Cortex-A53 cores complete the big.LITTLE CPU configurations.

The Mate 9’s CPU cores really reached higher peak frequencies than those in the Mate 8, but the differences are very small. The A53 cores get a negligible increase from 1.80GHz to 1.84GHz, while the A73 cores reach up to 2.36GHz versus the 2.3GHz for the Kirin 950’s A72 cores. It’s very interesting that Kirin 960’s A73 cores are clocked very lower than the Kirin 955’s 2.5GHz A72 cores, specially considering that ARM targets a peak frequency of 2.8GHz on 16nm means the Kirin 960 uses TSMC’s 16 FFC Fin FET process. With the Kirin 960, Hi-Silicon is more focused on reducing power consumptions , instead of chasing maximum CPU performances. that still based on the A73’s other advantages, particularly the improvements to the memory subsystem, the Kirin 960 really show a small performances gained relative to Kirin 950-955.

Between Mate 8 - Mate 9 

                    Perhaps the biggest criticisms of past Kirin SoCs were their seemingly under-powered GPUs. While Qualcomm pushed the performances and power envelope with its Adreno GPUs, and Samsung added eight or twelvecore configurations of ARM’s latest Mali GPUs to its Exynos SoCs, Hi-Silicon’s Kirin SoCs made due with more modest four core Mali configurations. Peak performance significantly trailed its peers, but Kirin’s lower power consumption limited the effects of thermal throttling. Ultimately, performance was very good enough for the majority of cases. The Mate 9’s Kirin 960 SoC marks a radical shift in HiSilicon’s GPU philosophy. Not only does it utilize ARM’s latest Mali-G71 GPU based on the all new Bifrost architecture, but it steps up to an eight core configuration running at an impressive 900MH the same peak frequency used by the Kirin 950 or 955’s much smaller GPU. The combination of additional cores and architectural improvements give the Mate 9 a significant peak performance advantage over the Mate 8’s Mali-T880 MP4 GPU, paving the way for new capabilities such as VR.

                The Mate 9 pairs its SoC with 4 GB of LP DDR 4 RAM, which is now standard for flagship phones. Internal storage is limited to 64 GB, unlike the Mate 8 that offered a choice between 32 GB, 64 GB, or 128 GB of NAND. Both the Mate 9 Pro for 128 GB and Mate 9 Porsche Design for 256 GB come with additional storage, and all three Mate 9 versions have a slot for a micro SD card to expand storage further.

                    Software features and configuration are also vitally important to performance. The Mate 9, like previous Huawei phones, included several enhancements to help apps launch faster and to keep the system feeling more responsives. Huawei’s EMUI uses the F2FS files-ystem and other optimizations to improve storage performances. There’s also Huawei’s Machine Learning algorithm that prioritizes system resources for CPU, memory, and storage to improve responsiveness and overall performance. This feature, which runs locally on the phone, monitors app usage, taking note of which apps are used at what times, and then anticipates the user’s needs, by preloading the predicted app, for example. Android already manages memory usage, evicting background apps to free up resources for active processes, but Huawei takes this further by closing memory-intensive background apps to ensure memory is available for prioritized apps. It also uses compression to increase the amount of data held in working memory.

It's briefly cover on connectivity options. It supports 802.11a/b/g/n/ac Wi-Fi for 2.4GHz and 5GHz, but only a single spatial stream enabling up to a 433Mbps PHY rate on a 80 MHz channel. Most flagship phones like HTC 10, LG G5, Motorola Moto Z or Moto Z Forced Droid, Samsung Galaxy S7, and iPhone 7 to name just a few thing offer dual spatial stream MU-MIMO, so the Mate 9 is a bit behind here. It does come with Bluetooth 4.2 LE, NFC, and even an IR blaster, though.

                         The Kirin 960 includes a brand new HiSilicon LTE UE Category 12-13 modem that achieves speeds of up to 600 Mbps on the downlink and 150 Mbps on the uplink to 2x20MHz carrier aggregation with 64-QAM. This new modem, which drops HiSilicon’s ‘Balong' branding, supports up to 8 data streams on the downlink using a combination of quad carrier aggregation 4x CA and 4x4 MIMO it's only for 2x CA. It also supports up to 256-QAM but not on all 8 streams. This gives it some flexibility in how it achieves its maximum throughput for 2x20MHz CA + 4x4 MIMO at 64-QAM or 4x20MHz CA + 2x2 MIMO at 64-QAM.

TD-CDMA 34 / 39 34 / 39

                         This modem gained another new capabilities: It now supports CDMA, which is important for carrier compatibility in China, and puts Hi-Silicon in the same group as Intel, Media-Tek, and Qualcomm for global network support. This modem represents a significant investment by Hi-Silicon, because it uses a completely new, custom design that does not use CEVA LTE IP like previous Balong modems. There are two different models of the Mate 9. The MHA-L09 model uses a single NanoSIM and does not support CDMA networks. The MHA-L29 model supports Dual SIM Dual Standby (DSDS), although one Nano SIM slot is shared with micro SD, so it can use either two NanoSIM cards or one NanoSIM and one microSD card. The second SIM supports 2G-3G operation using GSM (850-900-1800-1900 MHz),
