The Cortex-X3 and Cortex-A715 cores are the next flagship CPUs from ARM. The new cores come with a significant performance boost and will power premium Android phones in 2023. Continue reading to learn more about the Arm 2nd gen v9 CPUs.

Arm 2nd gen v9 CPUs Overview:

The Cortex-X3 builds on last year’s Armv9 architecture. Alongside this, the company has also introduced a new Cortex-A715 core and an improved Cortex-A510 core. 

Cortex-X3

To begin with the elephant in the house, the Cortex-X3 offers a 25% boost in performance over the current best Cortex-X2. It is also said to be more efficient, and capable of delivering the same level of performance while consuming less power.

Furthermore, Arm claims to deliver up to 34% higher single-threaded performance than the latest mainstream laptops. Android Authority compares it to the Intel Core i7-1260P, a power-hungry 28W CPU.

Cortex-X3 also improves upon DynamIQ Shared Unit (DSU-1010) platform and can now support up to 12 cores and 16MB of L3 cache. This allows for more scalability, allowing Arm CPUs to be adapted for everything from phones to high-end laptops.

Cortex-A715, Cortex-A510

The Cortex-A715 core, on the other hand, also brings a fair set of improvements; the most significant of which is the transition from 32-bit to 64-bit processors. This is Arm’s roadmap for fully transitioning to 64-bit, and we will see 64-bit only Android smartphones starting next year. It has a 20% higher energy efficiency than the last year’s Cortex-A710 cores. The performance increase is 5% and is said to match the performance of the Cortex-X1 CPU from 2020.

Arm has also upgraded the Cortex-A510 core for energy efficiency (5% more efficient than the previous generation). This should result in better battery life. 

Composition

With Arm releasing new CPUs, the 2023 flagship processor cluster will have Cortex-X3, Cortex-A715, and Cortex-A510 cores. Chipmakers (Qualcomm, MediaTek, and Samsung) may use 1+3+4 designs like the current flagship chips, or they can also go with 1+4+4 or 2+2+4 cluster designs.

Arm has announced its new flagship GPU called “Immortalis.” It is Arm’s first mobile GPU to come with hardware-based ray tracing. The GPU is targeted toward flagship Android users who are keen on gaming on their phones. In this article, we will be discussing the Intel Arm Immortalis GPU in more detail.

Arm Immortalis GPU Overview:

According to Arm, the new Immortalis-G715 GPU is designed for next-generation flagship smartphones. In addition, the company claims to offer a 15% improvement in performance with its new GPU.

Besides, Arm is raving about a two times improvement in architectural machine learning. Moreover, it should provide “ultimate mobile gaming and graphics experiences.”

Hardware-Based Ray Tracing

As mentioned, the Immortalis-G715 is the first Arm GPU to offer hardware-based Ray Tracing. According to Andy Craigen, the product management director of Arm, the main challenge of RT is high power usage.

However, per the Arm, the ray tracing on the Immortalis-G715 only uses 4 percent of the shader core area. The company also claims a 300 percent performance improvement via hardware acceleration.

Arm claims its partners and hardware are ready to utilize hardware ray tracing fully. The developer ecosystem, however, still needs to catch up.

Variable Ray Shading

With the announcement of Immortalis, Arm has also updated its Mali lineup of GPUs with the Mali-G715. In addition, it supports variable-rate shading, which allows for “significant energy savings and a performance boost.”

VRS lets the GPU focus the rendering on the parts that matter. So, for example, the foreground will have fine pixel granularity, whereas the background will render with coarse pixel granularity.

Arm Immortalis GPU Availability

The Immortalis GPU will be available in flagship smartphones in Q1 of 2023. Arm also shared a roadmap showing that they will follow up the Immortalis with a GPU dubbed “Titan” in 2023 and “Krake” in 2024.
