We test a lot of software here at Puget Systems, and in most cases what we are looking for is what hardware lets a given program run the fastest – or in some cases, what is the most cost effective. If you can get 95% of the best possible performance for half the price that it would cost to get a full 100%, for example, that is often a compelling way to go. However, ANSYS Mechanical (and FLUENT) present a different challenge: how can you get the best performance within the limitations of the ANSYS licensing model?
Clock speeds on modern Intel processors are not straight-forward, a fact that is attested to by the several articles we have published on that topic in recent years. This can lead to confusion over what CPU to pick when configuring a new computer, especially for higher-end workstations and servers with high core count processors. I am hoping this blog post will shed a little light on that subject, and help readers be better able to select the right CPU for their needs.
