      Server Description

      A compute-optimized virtual server featuring dedicated Intel Xeon processors and a balanced memory profile for single-threaded workloads.

      Compute Optimized

      Amazon Web Services c5.xlarge is a compute-optimized instance featuring 4 dedicated vCPUs and 2 physical Intel Xeon 8124M cores running at 3.4 GHz on the Nitro hypervisor. Built on the x86_64 architecture, it includes 8.0 GB of DDR4 memory, providing a 1:2 vCPU-to-RAM ratio. The instance does not include local storage or GPUs, and operates with a 1 Gbps baseline network bandwidth. Benchmark data shows average single-core CPU and single-threaded compression performance, though multi-core execution, memory bandwidth, and database operations fall into weaker performance tiers. This configuration represents a cost-efficient option for dedicated compute tasks with low memory requirements. It is best suited for workloads such as lightweight web serving, text processing, and single-threaded batch processing.

      Workload Profiles

      0.253Score
      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.
