Tablet Computing Performance and Battery Life

image of ANSYS Mechanical running on a tabletIn the first part of this two-part post about tablet computing and running ANSYS Mechanical, I laid out the specs of each of the tablets I tested. Now I’ll take a deeper dive and compare their performance related to computation and battery life.

Tablet Computing Performance Study

When comparing the performance of these two tablets, I used a high-end workstation as a baseline for which to compare the results, since a majority of engineers still perform FEA simulations on workstations or servers. This workstation contains two Intel Xeon E5-2670 processors (2.93 GHz), 128 GB of RAM, and a 500 GB SSD; it runs the 64-bit version of Windows 7. I ran ANSYS simulations with two different equation solvers: sparse direct and PCG iterative. The sparse direct solver is computationally demanding and requires high compute rates for good performance. The PCG iterative solver works differently and requires high-memory bandwidth to achieve strong performance. Some interesting data came from these runs. Continue reading
