      Server Description

      A memory-optimized x86 server featuring high-speed DDR5 RAM and advanced Intel matrix extensions for demanding enterprise database workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r7i.48xlarge is a memory-optimized server powered by Intel Xeon 8488C processors with 192 vCPUs and 1536.0 GB of DDR5 memory. Operating on the Nitro hypervisor, this x86_64 instance features a 3.2 GHz clock speed, 105 MB L3 cache, and advanced instruction sets like Intel AMX and AVX-512. It lacks local storage and GPUs, relying on a 50 Gbps baseline network bandwidth. Benchmarks place its multi-core CPU performance and memory bandwidth in the top 10%, with large-block reads reaching 454.59 GB/sec and Redis throughput hitting 183.87 million operations per second. The high memory-to-vCPU ratio makes it qualitatively cost-efficient for consolidating massive in-memory databases, though storage operations must utilize network-attached volumes. It is highly suited for enterprise database hosting, large-scale web serving, and memory-intensive data processing.

      Workload Profiles

      6.9Score
      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.
