Performance Metrics

Analyze Test Configuration:

RAMspeed SMP 3.5.0

Type: Triad - Benchmark: Floating Point

OpenBenchmarking.org metrics for this test profile configuration based on 4,582 public results since 26 February 2011 with the latest data as of 8 May 2024.

Below is an overview of the generalized performance for components where there is sufficient statistically significant data based upon user-uploaded results. It is important to keep in mind particularly in the Linux/open-source space there can be vastly different OS configurations, with this overview intended to offer just general guidance as to the performance expectations.
