CPU and System Topology
Server Description
An arm64-powered general-purpose instance delivering high multi-core density and strong memory bandwidth for parallelized workloads and caching layers.
Alibaba Cloud ecs.g6r.16xlarge is an arm64 general-purpose instance powered by a 64-core Ampere Altra processor clocked at 2.8 GHz, paired with 256 GB of RAM. Operating on a KVM hypervisor with dedicated CPU allocation, this server offers a balanced 4 GB of memory per core but lacks local storage and GPU accelerators. It features a 16 Gbps baseline network bandwidth. Performance benchmarks highlight strong multi-core capabilities, including a multi-threaded bzip3 decompression rate of 413.03 GB/sec and 82.33 million Redis SET operations per second, though single-core performance remains average. Additionally, it delivers a static web serving throughput of 33.73 GB/sec and handles medium-sized 7B LLM inference at 21.03 text generation tokens per second. The ARM-based architecture provides a cost-efficient profile for highly parallelized workloads, making this instance well-suited for multi-threaded applications, web serving, Redis caching, and containerized microservices.
