ANSYS R13 Lemans CPU Wall Clock Benchmark Results Before and After a Windows 7 64-bit SP1 Update
I was curious what sort of impact the Windows 7 SP1 upgrade would have on a new install of ANSYS R13. Would the Service Pack upgrade have a positive or negative impact on the ANSYS R13 and additionally the Lemans benchmarks? Here is what we found:
- Hardware test machine: Single socket 6 core AMD C32 running 2.6GHz, 8GB of RAM, 2 x 160GB Intel SSD drives in RAID0, Windows 7 Professional
- Benchmarks completed by Clinton Smith, Consulting Mechanical Engineer CFD and Thermal Analysis at PADT, Inc.
Results:
- The benchmark results appear approximately the same before and after the install of the Service Pack.
- No apparent issues or crashes with ANSYS R13 after installing the Windows 7 Service Pack 1 update
- Six core benchmarks and one core benchmarks are slightly faster after SP1 upgrade.
- Four core and two core benchmarks are slightly slower after SP1 upgrade:
