      Server Description

      A high-density compute instance featuring 128 vCPUs and 256 GB RAM, optimized for parallel processing and high-throughput network workloads.

      Compute Optimized

      Amazon Web Services c6a.32xlarge is an x86_64 compute-optimized instance powered by a 3.6 GHz AMD EPYC 7R13 processor. It features 128 vCPUs (64 physical cores), 256.0 GB of DDR4 memory, and a 50 Gbps baseline network speed, running on the Nitro hypervisor. The instance does not include local storage or GPU accelerators. In benchmarks, the c6a.32xlarge delivers top-tier multi-core CPU performance and memory bandwidth for cached reads, alongside strong cryptographic execution. Single-threaded tasks and text processing perform in the average tier. This hardware profile is qualitatively cost-effective for highly parallelized, compute-heavy workloads that rely on network-attached storage. It is suited for software compilation, ray tracing, static web serving, and database operations.

      Workload Profiles

      3.91Score
      Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
