Oracle Giving Away 4-Core 24 GB Memory Ampere Instances
I&#x27;ve run CoreMark PRO on one of those free Ampere 4-core + 24 GB RAM instances, running Oracle Linux 8.4. TL;DR: that free instance performs very very well.<p><pre><code>  WORKLOAD RESULTS TABLE

For comparison, this is the result on my laptop: Intel Core i7-10850H @ 2.70 GHz, with 32 GB RAM and RHEL 8.4 x86_64:<p><pre><code>  WORKLOAD RESULTS TABLE

So that free Ampere instance performs slightly better than my i7-10850H on single-core, and just 10% slower on multi-core (and that&#x27;s considering my i7-10850H has 6 cores, while the Ampere has only 4 cores!!!).
