n my impression, the later ones are all supposed to be successors of the previous but within about the same chip area. The A55 is basically a refined A53 with support for DynamIQ. The point of the A510 was support for ARMv9 with SVE2, but it is wider also because people expect faster processors. To amortise the cost of the larger back-end it lost 32-bit support and there's an option to make a cluster of two share the same FP/SIMD/SVE unit and L2 cache.
- realjhol 3y agoThe A53 is a fantastic workhorse for all kinds of embedded workloads. I was worried bloat would creep into later models, while the tried and true A53 moves toward obsolescence. From what you're saying, it seems like they are trying not to get carried away with it.

- Findecanor 3y agoThe ARM Cortex-A520 was announced yesterday. Apparently ARM realised that the A510 was too big, and removed an ALU unit (back to two like the A55).
