Ampere’s Altra 64-bit, 80-core processors deliver predictable performance, high scalability, and power efficiency. This device is single-threaded, runs at consistently high frequencies (up to 3.3 GHz), and is built with large low-latency private caches; a 64 kB L1 I-cache, 64 kB L1 D-cache, and a 1 MB L2 cache. Coherent mesh-based interconnect topology provides efficient bandwidth with 32 distributed home nodes and directory-based snoop filters to enable seamless connectivity between the cores. Supporting eight 2DPC, 72-bit DDR4-3200 channels, the Ampere Altra processor offers high bandwidth and memory capacity of up to 4 TB per socket. It also supports 128 lanes of high speed PCIe Gen4 and 8×72 ECC protected DDR4 3200 memory and comes in a 77.08 mm × 67.00 mm 4926-Pin Flip Chip Land Grid Array package.
The ADLINK COM-HPC server module (200 mm x 160 mm) utilises the Ampere Altra chip and has 768 GB DDR4 memory at 3200/2666 MT/s, 64 PCI express lanes, 4 USB 3.0/2.0 ports, and runs off 12 V / 5 Vsb power. The module supports the following operating systems: Windows PE, VMware ESXi-Arm Fling v1.8, Fedora Server 35, Ubuntu Server 20.04.3, FreeBSD 13.0-RELEASE, CentOS stream 9, and Debian 11.2, and can be used to evaluate Ampere’s technology in a computing application.
