Among the chip designs unveiled today by Arm is the Immortalis-G715, a new high-end mobile GPU. It is scheduled to hit the market alongside mobile devices next year. According to Arm, the chip can outperform its previous high-end GPU by 15%.
Hardware-level support for ray-tracing methods is the performance-enhancing feature of the G715 highlighted by Immortalis. Ray tracing is a rendering technique that improves the graphical fidelity of video games. Since it requires large processing resources to run, this technology was previously only widely supported on desktop GPUs.
Arm’s previous flagship GPU also supported ray tracing. However, it only supported the technology at the software level, while the new Immortalis-G715 supports ray tracing enhancements at the hardware level. According to Arm, the improvements allow for a significant increase in performance.
“Ray tracing on the Immortalis-G715 requires only 4% of the shader core area, while delivering a performance boost of over 300% through hardware acceleration,” said Andy Craigen, Managing Director of arm products.
The Mali-G715, another new high-end mobile GPU, joins the Immortalis-G715 in the Immortalis-G715 family. The Mali-G715 supports variable rate shading, a rendering technology that can increase the frame rate of video games while improving power efficiency. According to Arm, the chip outperforms its predecessor in terms of performance and power efficiency by 15%.
CPU improvements
The Cortex-X3 is Arm’s new flagship mobile CPU, which can power both phones and laptops. When put into a smartphone or tablet, the CPU outperforms previous generation Arm chips by up to 25%. When powering a laptop, the Arm Cortex-X3 can run applications 34% faster.
The Arm Cortex-X3 is not a complete CPU, but rather a CPU core, which is the fundamental computing component in a processor that performs calculations. Mobile processors typically have multiple cores. Memory, for example, is one of the supporting components.
Arm is launching the DSU-110 technology along with its Cortex-X3 CPU design to aid the development of mobile processors. Chipmakers can use the technique to merge up to 12 Cortex-X3 cores into a single processor. The DSU-110 allows CPUs to be equipped with up to 16 megabytes of L3 cache, a kind of high-speed memory used by processors to store the data on which calculations are performed.
“Compared to the previous generation, the newly enhanced DSU-110 supports 50% more cores, along with the latest ISA capabilities,” Saurabh Pradhan, senior director of product management at Arm, stated in a blog post. “These enhancements increase flexibility for our partners and provide the resources needed to unleash the full potential of our CPUs to improve user experiences.”
Arm introduces the Cortex-A715, a new CPU design for mobile devices that require a balance between performance and battery savings. It consumes 20% less power than its predecessor, the Cortex-A710. The new chip also promises to improve performance by 5%.
Many mobile CPUs combine fast cores with slower, more efficient ones designed to maximize battery life. To maximize performance, compute-intensive programs run on high-speed cores. To save power, less demanding programs are installed in the most efficient region of the CPU.
Arm provides a custom semiconductor design that companies can use to make the low-power cores for a mobile CPU. The Cortex-A510 chip design debuted last year. Arm has announced an upgraded version of the Cortex-A510 with a 5% increase in power efficiency.
Arm’s latest CPUs include two cybersecurity features aimed at reducing the danger of cyber attacks. The first enhancement restricts the malware’s ability to access a device’s memory. Asymmetric MTE, the second new security feature, detects and rejects certain types of cyberattacks that aim to overwrite data on a device with malicious code.
“Asymmetric MTE provides greater flexibility in terms of speed, accuracy, and targeting of these security weaknesses,” Pradhan said. “This aids software development by enabling more robust applications, while also enabling a greater spread of MTE throughout the ecosystem.”
