I am new to running the Linpack Benchmark in Windows 7 and have a few questions. I am running (2) Intel E5-2680 CPU in a Gigabyte GA-7PESH2 server. The test was originally run about 10 months ago using Linpack 10.3.11.019 for 65528 runs. At output I had the following:
CPU Frequency: 3.416 GHZ
I recently ran the same test after updating the BIOS and got the following:
CPU Frequency: 2.639 GHZ
I then downloaded the new Linpack version 11.0.5.009 and got the following (*note I was running the version as is with no changes, so I ran only 40000 equations)
CPU Frequency : 2.698
Can anyone help me understand or point me in the right direction as to why I am losing GFLOPS . Also is the difference between the two Linpack versions so great that I could have that big of a discrepancy? Thank You.
