MacBook Pro GPU underclocked?

[lavem]

I just noticed this on The Register who in turn found it on MacBidouille

Apple appears to have underclocked the ATI Radeon Mobility X1600 graphics chip in its MacBook Pro laptop. According to one online report, the GPU's core runs 35 per cent slower than the clock speed recommended by ATI. The memory clock is 41 per cent below par.

Either it is a heat/noise issue or maybe they crippled the Windows driver to make OS X graphics performance look faster?

Apple do this in most hardware. My iMac G5 rev c is very underclocked.
