> ThunderX2 is a 14nm FinFET design, and the company claims it will deliver 2 to 3 times the performance of ThunderX on select workloads with a higher performance to power ratio. Their plan for the X2 is to include 54 ARMv8.2 cores with a target frequency of 2.4 to 2.8 GHz and up to 3 GHz in turbo mode (versus their current 28nm, 48 core, 2.5GHz design), 32MB of what Cavium calls shared Last Level Cache (LLC), 6 DDR4 memory interfaces running at 3200MHz (1 DPC) or 2966MHz (2 DPC), multiple 10/25/40/100 Gb/s Ethernet (KR) interfaces, enhanced virtualization support (including IO), ARM Holdings Trustzone security and a variety of hardware accelerators.

Is ARM's TrustZone not the same as Intel's ME? At least I remember that AMD uses a ARM Core with TrustZone in it's x86 CPU's to basically achieve the same (or something similar) as Intel's Management Engine.

- jaen 10y agoTrustZone is basically the name for the ring -1/hypervisor access level for ARM CPUs, not a separate "engine" or product. It can be used to run and isolate code at a higher privilege level than an operating system eg. for DRM.
