Arm Roadmap 2023/2024: CPU cores, GPUs and interconnects are accelerating


As part of Total Compute Solutions 2022 (TCS22), Arm today has the new CPU cores Cortex-X3, Cortex-A715 and Cortex-A510 Refresh as well as the new GPUs Immortalis-G715, Mali -G715 and Mali-G615 introduced. The company's roadmap gives an initial outlook on developments for 2023 and 2024.

As part of the Client Tech Days in Austin, Arm gave a rough outlook on the developments to be expected in the area of ​​TCS in the coming years. The company is still working with code names and has not yet answered questions, but the roadmap shows where the journey will go.

CXC23 and Hunters follow X3 and A715

Following today's new products, Arm will again be launching a new Cortex-X core on the Cortex-X3 in the coming year with the TCS23, probably under the name Cortex-X4, which is currently still listed as the CXC23 in the roadmap. In addition to the largest prime core, there is also a new core for the new performance cores under the code name “Hunter” as the successor to the still current Cortex-A715. Hunter is to be replaced by “Chaberton” in 2024.

Hayes will replace the A510 after only two years

Both are expected developments that continue the previous course in Arms Roadmaps. Much more interesting, however, is the pace that the developers are setting in the area of ​​efficiency cores. On the Cortex-A510, which was only introduced in 2021 and its refresh for this year, a new efficiency core with the code name “Hayes” is to be presented after two years, which should be used for at least two years.

This is remarkable in that Arm has previously used a lower cadence for the efficiency cores (with the exception of the second model). The Cortex-A7 was introduced in 2011, the Cortex-A53 in 2012, the Cortex-A55 only in 2017 and four years later last year the Cortex-A510, which was only slightly revised for this year and bears the same name. In the TCS22 and TCS23, after only two years, the Cortex-A510 is to be used again with a new efficiency core.

Hayden follows DSU-110

In addition, a new DynamIQ Sharing Unit Cluster will be launched next year under the name “Hayden” and will replace the DSU-110, which was also only introduced last year. New for this year is a possible configuration of up to twelve cores (8 + 4 + 0) within the cluster.

MMU and interconnects remain first

For the third year in a row, the MMU-700 (Memory Management Unit), the CoreLink CI-700 Coherent Interconnect and the CoreLink NI-700 Network-on-Chip Interconnect, which were also presented with the TCS21, are to be used outside of the DSU. The MMU-700 should also continue to be used with the TCS24, but for the CI-700 and NI-700 an interconnect combined to form a solution is available with “Tower”.

Valhall GPU architecture is about to be replaced

In terms of graphics units, the end of the Valhall architecture has probably been reached with the Immortalis-G715, Mali-G715 and Mali-G615, which has been used for four GPU generations since the Mali-G77. This is indicated in particular by a second roadmap from Arm, which shows a break after Valhall. Arm's new graphics units are planned for 2023 and 2024, codenamed “Titan” and “Krake”. The future flagships with ray tracing should continue to run under the product name Immortalis, despite the new architecture, because otherwise they wouldn't be immortal.
