      Server Description

      A memory-optimized x86_64 platform featuring 1.5 TB of DDR5 RAM and 192 vCPUs for memory-intensive enterprise workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r7i.48xlarge is a memory-optimized server instance featuring 192 vCPUs and 96 physical Intel Xeon 8488C cores running at 3.2 GHz. It is equipped with 1536.0 GB of DDR5 memory operating at 5 GHz, but contains no local storage or GPUs. Operating on the Nitro hypervisor, the instance delivers top-tier multi-core CPU and memory bandwidth performance, placing in the top 10% for stress-ng multi-core and uncached memory read/write benchmarks. It supports advanced instruction sets like AVX-512 and Intel AMX, yielding strong results in cryptographic and database operations. With a baseline network bandwidth of 50 Gbps, this instance is suited for large-scale in-memory databases, memory-intensive data processing, and medium-to-large LLM inference workloads.

      Workload Profiles

      7.09Score
      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.
