ARM announces its Cortex-X4, A720 and A520 cores for next-generation SoCs

ARM has presented its latest architecture Armv9.2 with a new generation of CPU and GPU cores that will give life to the next processors and SoCs based on the company’s architectures, such as those that give life to the vast majority of smartphones in the world. We have published a comprehensive article explaining what’s new in CPU core architecture, and another article on GPUs.

There will be three cores available: The Cortex-X4 which is crowned as the most powerful ARM core for the most demanding tasks such as gaming AAA titles, the Cortex-A720 for sustained multicore performance, and the Cortex-A520now with even more efficiency for more basic and background tasks.

These cores can be combined in different big.LITTE configurations, from SoCs with 1 Cortex-X4, 3 Cortex-A720 and 4 Cortex-A520 for example, up to exclusive configurations of up to 14 Cortex-X4 cores for laptops, and all the combinations that the manufacturers of SoCs with these architectures need. This is possible thanks to the DSU-120 that allows 32 MB of L3 cache and all kinds of combinations with up to 14 cores of different types.

They support LPDDR5 memories at 8,533 MHz and will be accompanied by the new fifth-generation GPUs, in addition to the CoreLink CI-700, NI-700 and MMU-700 interconnection systems.

The ARM Cortex-X4 they increase up to 24% the performance of the last generation Cortex-X3. with averages of 15% more performance. Its cache increases up to 2 MB per core.

The Cortex-A720 They have managed to increase performance and efficiency, in fact, at the same speed and conditions, it consumes the same as a Cortex-A715 with greater efficiency.

These cores are designed for tasks that require multi-core performance on a sustained basis, leaving the Cortex-X4 (in a typical SoC configuration for smartphones, 1+3+4 or similar configurations are usually used) as CPU for maximum performance single-thread tasks.

Finally, the Cortex-A520 They also adopt architecture Armv9.2 and now with more efficiency. In fact, elements such as one of the 3 ALUS that the A510 had to go to 2 ALUs have been removed, which saves energy, but that space is used to add more elements that compensate for the loss. In the end, we have 8% more performance under the same conditions as a Cortex-A510 (matching the two in frequency), but to maintain the same performance as an A510 it needs 22% less power.

Next to them, the Immortalis-G720, Mali-G720 and Mali-620 GPUs with the highest efficiency to date

In addition to the CPU cores, the next-generation SoCs will be accompanied by ARM’s new fifth-generation GPUs. Specifically, there will be three models, from the powerful Immortalis-G720 to Mali-G620, going through the Mali-G720all of them form the company’s most efficient and powerful generation of GPUs.

All of them share architecture and technologies, with support for Ray tracing, VRS or DVS, and the main difference is the number of cores.

Specific, the Immortalis-G720 will have a configuration with 10 to 16 cores depending on the chosen configuration. It will be the most powerful GPU of the three and will be geared towards higher-end devices.

It is followed by Mali-G720, a model that will arrive with configurations of 6, 7, 8 and up to 9 cores. Below we will find the Mali-G620with 5 cores or less.

These CPU and GPU cores will be part of the next generation of SoCs from major companies such as Qualcomm and its Snapdragon, MediaTek, Samsung and also other manufacturers that are based on ARM designs for all types of devices and ranges, although, without a doubt, Where they will have the greatest impact will be in the smartphone markets.
