Hello,

I have benchmarked FPC 2.7.1 64-bit against the newest version
of tdm-gcc 64-bit and the FreePascal scimark2 benchmark is much better:


Here is the scimark2 results on my Quadcore Q6600:


FPC 2.7.1 64-bit gives:

Mininum running time = 2.00 seconds
Composite Score MFlops:   578.95
FFT             Mflops:   393.07    (N=1024)
SOR             Mflops:   717.27    (100 x 100)
MonteCarlo:     Mflops:   113.03
Sparse matmult  Mflops:   814.43    (N=1000, nz=5000)
LU              Mflops:   856.94    (M=100, N=100)


And tdm-gcc 64-bit gives:

Using       2.00 seconds min time per kenel.
Composite Score:          754.95
FFT             Mflops:   664.22    (N=1024)
SOR             Mflops:   720.90    (100 x 100)
MonteCarlo:     Mflops:   223.05
Sparse matmult  Mflops:   985.50    (N=1000, nz=5000)
LU              Mflops:  1181.08    (M=100, N=100)


So  if you have noticed on LU there a 38% difference in performance
and on Sparse matmult there is a 21% difference in performance
and on SOR it's the same performance
and on FFT there is 69% difference in performance.
and on the overall Composite Score there is only 30% difference in 
performance.


So i think that FPC 2.7.1 64-bit is much better and i think
FPC will get much better on performance in the future.

You can download FPC 2.7.1 64-bit from here:

FPC 2.7.1 64-bit is much better on scimark benchmark than Delphi XE 64-bit


Thank you,
