Neoverse E1

The Neoverse E1 processor is a new class of highly efficient CPU designed specifically for throughput compute workloads.

Neoverse E1 block diagram

Getting started

The Arm Neoverse E1 CPU delivers best in class throughput efficiency. It incorporates a new simultaneous multithreading (SMT) microarchitecture design. With SMT, the processor can execute two threads concurrently resulting in better aggregate throughput performance.

The Neoverse E1 delivers 2.1x more compute performance, 2.7x more throughput performance and 2.4x better throughput efficiency compared to the Cortex-A53. The design is highly scalable to support throughput demands for next generation edge to core data transport.
