Today Cavium. announced the second generation of their ARM Holdings CPU targeted at the enterprise server market. The new chip, the Thunder X2 is expected to be available in the second half of 2017 and appears to be one of the best design specs that has been disclosed. (There is this small matter of executing to the plan that is required.) It is the follow-on to their Thunder X CPU that began sampling early 2015 and was released for production later last year. Thunder X2 is a 14nm FinFET design fabricated by TSMC, and the company claims it will deliver 2 to 3 times the performance of Thunder X 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 Trustzone security and a variety of hardware accelerators. In fact, Cavium’s best opportunity to make an impact in the enterprise space is through these accelerators and a laser focus at providing undeniable value propositions.
