I ran an Intel MKL LINPACK test on an Intel Core i7-14700K processor and got a peak performance of 557 GFLOPS which seems quite unrealistic.

The 155 GFLOPS value for the 1000 size seems plausible, but 557 GFLOPS is too high. Does anybody have an idea how it could happen?
I used the following suite:

The test was started using the following command:
./runme_xeon64
