With the launch of Snapdragon 865 and Snapdragon 765/765G SoCs, Qualcomm announced support for updateable GPU drivers via app store. Xiaomi became the first OEM to deliver driver update to Adreno 650 GPU present in its Mi 10, Mi 10 Pro, and Redmi K30 Pro. Now, following the footsteps of Qualcomm, ARM also announces similar support for its Mali GPUs.

GPU driver updates on Android has been hindered for years as it takes months for OEMs to push them via OTA update. To solve this problem, Qualcomm introduced updateable GPU drivers through smartphone manufacturer’s default app store like Google Play Store.

This way users can get access to new features from OpenGL or Vulkan API without waiting for OTA system updates from the manufacturers. Also, graphic performances and bug fixes can be easily maintained with this approach just like on PCs.

Thus, realizing the benefits of this move, ARM has also joined the bandwagon but did not reveal the GPUs that will support it. As XDA Developers points out, it could be initially supported by the newly announced Mali-G78 GPU, which debuted alongside Cortex-A78 CPU architecture.

Additionally, ARM also announced support for Android GPU Inspector for its upcoming GPUs, which is an open-source profiling tool that helps game developers to optimize graphic performance.

Samsung recently completed the post production for its upcoming 5nm chipset, Exynos 992. And now, reports from South Korea reveal that the mass production of the new 5G processor begins in August 2020 and will feature ARM’s latest Cortex-A78 cores and Mali G78 GPU.

The new cores and GPU technology is said to be more powerful and efficient than the previous generation’s Cortex-A77 cores and Mali-G77 GPU. ARM claimed that the new core generation will be 20 percent more energy efficient than its predecessors with a 25 percent bump in GPU performance as well. Unlike the Exynos 990, the Exynos 992 SoC is said to bring major upgrades over just minor improvements.

A notable improvement is the shift to the new 5nm fabrication process, which will be the company’s first. In comparison, Qualcomm’s current flagship mobile processor, the Snapdragon 865, uses a custom version of the ARM Cortex-A77 cores and Cortex-A55 for low power tasks. So we can expect the Exynos 992 SoC to rival the Snapdragon 865 Plus, which may launch later this year.

Samsung’s Galaxy Note 20 series may be the first handset to feature the Exynos 992 processor. In a financial report, the South Korean tech giant confirmed the launch of upcoming smartphones including the Galaxy Note 20. Although, the official announcement is still a while away, so stay tuned more updates.

During the 2020 TechDay event, ARM announced two new CPU microarchitectures — Cortex-A78 and Cortex-X1 CPU for flagship performance design. Along with that, the company has also introduced a new Mali-G78 GPU.

So, it’s safe to assume that the next-generation flagship smartphones getting launched in 2021 will have ARM Cortex-A78 CPU and Mali-G78 GPU. For those who are unaware, chipset makers like Qualcomm, Huawei, Samsung, etc. use designs created by ARM to make their own SoCs that powers all the smartphones.

ARM says that the newly announced Cortex-A78 CPU core design is “unquestionably our most efficient Cortex-A CPU ever designed for mobile.” It is claimed to offer a 20 percent increase in performance compared to last year’s Cortex-A77 design while staying within a 1-watt power budget.

The new Cortex-A78 pretty much continues Arm’s traditional design philosophy on balance between performance, power, and area (PPA). ARM has a track record of being able to provide competitive performance with low power consumption and small die areas.

The company has also introduced a new Cortex-A custom program. With this, its partners can create their own specialized Cortex CPU in conjunction with ARM for their specific purposes beyond the stock Cortex-A78. The first of those chips is the ARM Cortex-X1.

The ARM Cortex-X1 will offer up to a 30 percent peak performance improvements over the Cortex-A77. The “Cortex-X Custom Program” is an evolution of “Built on Arm Cortex Technology” program that enabled customers to collaborate early in the design phase of a new microarchitecture, and request customizations to the configurations, such as a larger ROB, differently tuned prefetchers, or interface customizations for better integrations.

Besides new CPU designs, the company has also introduced a pair of new mobile GPUs — Mali-G78 and Mali-G68. While the G78 GPU is aimed at flagship smartphones, the G68 is meant for offering similar performance at a more affordable price point.

The new Mali-G78 supports 24 cores, up from 16, and the company promises that it will enable up to 25 percent increase in graphics performance compared to last year’s Mali-G77. ARM has also announced a new Ethos-N78 neural processing unit (NPU) which is promised to offer up to 25 percent improved performance efficiency over the Ethos-N77.

The Mali-G68 is the company’s first GPU targeted at the “sub-premium” market. It retains the FMA, dependency tracking, and tiler improvements from the G78 and comes with Asynchronous Top Level clock speed control. However, this budget GPU only scales between one and six cores.
