◆ Cortex-A78
The Cortex-A78 has the same architecture as the Cortex-A77, which is the previous generation CPU. However, by optimizing its microarchitecture, it aims not only to improve performance, but also to improve efficiency in both power consumption and area size, Arm said.
With 1W output, the single-core performance of Cortec-A78 is 20% higher than that of Cortex-A77, power consumption is reduced by 50%, and energy efficiency is significantly improved. In addition, the 'DynamIQ cluster,' which combines four Cortex-A78 and four Cortex-A55, will improve performance by 20% over the cluster of four Cortex-A77 and four Cortex-A55.
In addition, the Cortex-A78 is extremely efficient per milliwatt by reducing the L1-I cache and L1-D cache, and it has high computing power even in mobile devices that require miniaturization such as folding smartphones. Can be demonstrated. Arm argues that it can support the support for 5G, which will become popular in 2020.
◆ Cortex-X1
Cortex-X1 was announced as part of the '
In addition, Cortex-X1 single-threaded integer arithmetic performance is improved by 22%. It also doubles the machine learning performance compared to the Cortex-A77.
◆ Mali-G78
The same Valhall architecture as the previous generation Mali-G77, the Mali-G78 supports up to 24 cores with 25% performance improvement. “We enable high-quality mobile gaming experiences, immersive entertainment experiences, and more complex games, video, cameras, and security features on mobile devices,” Arm said.
Compared to the previous generation, the Mali-G78 has improved drawing performance by up to 17% in 3D games that require complicated CG rendering such as smoke and trees, and about 15% in computing performance related to machine learning using GPU. I am. A low-priced GPU 'Mali-G68' for the middle range with up to 6 cores was also announced.
◆ Ethos-N78
Machine learning has come to be used in various fields such as image processing and augmented reality (AR) in smartphone applications. Although the machine learning workload itself can be executed by the CPU, the Ethos-N78 is an NPU specialized for machine learning separately from the CPU. The Ethos-N78 offers up to 30% higher area efficiency than the previous generation Ethos-N77, doubling peak performance, increasing performance efficiency by 25% and DRAM bandwidth efficiency by 40%. This will allow machine applications to perform more efficient machine learning-related operations in software applications while maintaining longer battery life, Arm said.
Kim Jun Suk, Vice President, SoC Design, Samsung Electronics, said, “Samsung and Arm have a strong technology partnership. The Cortex-X Custom program marks Arm in a new direction. Is excited about enabling innovation for the next-generation user experience in the Android ecosystem. '
`` Arm's new premium solution is a performance- and power-efficient platform that will enable Unity's many creators to make their everyday lives easier for everyone, '' said Ralph Houbert, Vice President of Research and Development at Unity. Will seamlessly deliver an immersive, next-generation network experience that will shape the network. '
