MBA 13" 2011 has much higher GB score in Windows

[mildj84ns]

My 2011 MacBook Air 13" has much higher Geekbench score in Windows then in OS X.
It scores around 6000 in OS X while the score in Windows is around 7000

This is my configuration:
i5-2557M
4 GB 1333 MHz
256 GB Samsung SSD
OSX 10.8.2 and Windows 7 dual boot

Is it because graphics memory? Since OS X uses only 384 MB while Windows uses 1600+ MB

It's a known issue with the Windows version of GB always results in higher numbers than the OS X or Linux versions of the software.

I call "bug".
