At the end of March 2021, Arm v9, the latest version of the ARM architecture used in smartphones around the world, was announced. Armv9 enables much faster machine learning through SVE2 technology and better hardware security through memory tagging extensions. The details of Armv9 are summarized in the following articles.

And this time, three new CPUs that adopted Armv9, 'Cortex-X2', 'Cortex-A710', and 'Cortex-A510' were announced. The Cortex-X2 is the successor to the Cortex-X1 , the Cortex-A710 is the Cortex-A78 , and the Cortex-A510 is the successor to the Cortex-A55. Performance is improved by 16% for Cortex-X2, 10% for Cortex-A710, and 35% for Cortex-A510 compared to the previous model.



And the machine learning performance is 3 times better for Cortex-A510, 4 times better for Cortex-A710, and 8 times better for Cortex-X2. Looking at the graph below, we can see that the machine learning performance of the Cortex-A510 is superior not only to the Cortex-A55 but also to the Cortex-A78.



Cortex-A55, the previous model of Cortex-A510, has been a standard processor for smartphones since 2018. The Cortex-A510 uses a smaller core than its predecessor, with 35% better performance and 20% more efficiency. According to Arm, the Cortex-A510 is stronger than the

Cortex-A57 and has performance close to that of the Cortex-A73.

Arm has been working on the development of a successor model to the Cortex-A55 that uses Arm v8. However, when the Android Authority contacted Arm, 'We were considering accelerating the release of the successor to the Cortex-A55 (based on Armv8), but instead switched to prioritizing the Cortex-A510 based on Armv9.' It seems that the answer was returned.

Cortex-A710, which is the successor model of Cortex-A78, is a CPU located in the middle range among Arm CPUs. It doesn't have as powerful computing power as the Cortex-X2, but it's a more efficient CPU. Compared to the previous model Cortex-A78, the performance is improved by 10%, but the efficiency is improved by 30%.



The flagship model Cortex-X2 is the successor to the Cortex-X1 used in SoCs such as Qualcomm's Snapdragon 888 and Samsung's Exynos 2100. The Cortex-X2 is said to have 16% better performance than the Cortex-X1, but there is no detailed mention of efficiency.



In addition, Arm has announced plans to completely remove 32-bit support from smartphone processors in 2023. Of the three processors announced today, the Cortex-A510 and Cortex-X2 support 64-bit, while the Cortex-A710 supports 32-bit.

In addition, Arm has also announced four new GPUs, the 'Mali-G710', 'Mali-G610', 'Mali-G510' and 'Mali-G310'.

The flagship model is the Mali-G710, which has 16 cores. Compared to the previous model '

Mali-G78 ', the number of cores has been reduced from 24 cores to 16 cores, but machine learning performance has improved by 20% and efficiency has improved by 35%.

The Mali-G610 is a GPU with almost the same performance as the Mali-G710, and the major difference is the number of shader cores. If there are 7 or more shader cores, it will be Mali-G710, and if it is less than that, it will be Mali-G610.

The Mali-G510 and Mali-G310 are cheaper entry-level GPUs, and are positioned as successors to the Mali-G57 and Mali-G31, respectively. The Mali-G510 is over 100% better in performance, 22% more efficient and more than 100% better in machine learning performance than the Mali-G57. On the other hand, the Mali-G310 has 6x better texturing performance and 4.5x better Vulkan performance than the Mali-G31. In addition, when Android Authority contacted Arm, it seems that there was a reply that 'Mali-G310 can be expected to improve performance by 100% compared to Mali-G31'.



All four new GPUs feature the Valhall architecture and Arm Fixed Rate Compression with lossless compression, which can save 60% bandwidth and improve performance by 80% for content such as games and videos. It is said that it will be.
