Hello,

Here it is:

FreePascal 2.7.1 32-bit

Mininum running time = 2.00 seconds
Composite Score MFlops:   468.86
FFT             Mflops:   236.54    (N=1024)
SOR             Mflops:   712.89    (100 x 100)
MonteCarlo:     Mflops:    75.36
Sparse matmult  Mflops:   441.47    (N=1000, nz=5000)
LU              Mflops:   878.03    (M=100, N=100)


And Delphi XE4 32-bit

Mininum running time = 2.00 seconds
Composite Score MFlops:   396.12
FFT             Mflops:   233.56    (N=1024)
SOR             Mflops:   708.70    (100 x 100)
MonteCarlo:     Mflops:    75.34
Sparse matmult  Mflops:   243.81    (N=1000, nz=5000)
LU              Mflops:   719.16    (M=100, N=100)

So FreePascal 2.7.1 32-bit is in Composite Score 18% faster
than Delphi XE4 32-bit on the scimark2 benchmark.


And FreePascal 2.7.1 64-bit is in Composite Score 23% faster than
FreePascal 2.7.1 32-bit on then scimark2 benchmark.



Thank you,
Amine Moulay Ramdane.
