The first new ARM architecture in the past decade, ARMv9, was introduced in March this year. Today the company unveiled the first ARMv9-based CPU and GPU designs that will power the next wave of smartphones – especially flagships – arriving in 2022. The company is targeting not only smartphones but also laptops with its new CPU and GPU designs based on the ARMv9 architecture.
The most important product coming out of Arm’s Kitty today is the Cortex-X2 ‘Prime’ core, the successor to the Cortex-X1 introduced last year. The Cortex-X2 is part of the CXC program that allows OEMs to partner with Arm to develop a custom high-performance X-core for their devices. The goal is to increase single-thread performance by 30% in 2021 flagship Android phones with a Cortex-X1 chip inside. The company also advertises a 40% increase in performance compared to “mainstream 2020 laptops” while the L3 cache has increased to 16MB.
Arm’s big.LITTLE core design (performance cores + efficiency cores) has been in active service for some time. The next snake to carry the torch is that Cortex-A710 ‘large’ CPU core that replaces last year’s Cortext-A78 design. With the Cortex-A710 core, the company is promoting 30% more energy efficiency and a 10% increase in performance, as well as a two-fold increase in ML-based tasks. The new “big” core is expected to appear in a broad class of devices ranging from smartphones and laptops to smart TVs and other smart home devices.
And finally, we have the Cortex-A510 ‘LITTLE’ efficiency core, which is supposedly 20% faster, 35% more energy efficient, and three times better when it comes to machine learning and related tasks. It can be used in a variety of core cluster configurations for devices such as phones, XR wearables, and smart home devices, to name a few.
At its heart is the new DynamIQ Shared Unit-110, which opens the doors to multiple core cluster configurations and allows partners to design their own chips based on the exact performance profile they desire.
For example, a cluster of four Cortex-X2 and four Cortex-A710 cores would be ideal for high-end laptops. A tri-cluster design (1 + 3 + 4) is known to work for smartphones, while smart home devices can pack four ‘SMALL’ cores for undemanding computing scenarios. According to Arm, the DSU-110 offers 5 times the bandwidth, higher multiprocessor output, lower latency, and better scalability.
Arm is also introducing new graphics solutions. At the top of the food chain is the new flagship GPU Mali-G710 This is said to provide a 20% increase in performance when it comes to demanding tasks like gaming, 20% more energy efficiency, and 35% improvement on machine learning based tasks. The company wants to integrate its new flagship GPU into Chromebooks and high-end smartphones.
A slightly less powerful alternative to this would be the Mali-G610 GPU, which replaces the Mali-G68 graphics engine from last year. These “Sub premium” The solution borrows a lot of elements from its top siblings, but aims to deliver a smooth AAA gaming experience on upper-midrange smartphones.
in addition, With the Mali-G510 and Mali-G310, Arm is expanding its portfolio with some new mid-range and entry-level GPUs. Aside from boosting performance, these new offerings are also designed to be more energy efficient and have been designed with devices such as budget smartphones, AR and VR devices, and Chromebooks in mind, to name a few.
